20°C for an hour is fine for using larger (1mL of bacterial culture, plasmid) amounts of DNA The DNA pellet will not always be visible depending on how much DNA you are precipitating. So always take care in loading your samples in the centrifuge to remember the direction they are facing. The DNA pellet will be on the part of the tube facing the outside of the centrifuge. This protocol will precipitate all nucleic acids, not just DNA. If you do not want RNA in your sample, one of the many ways to deal with it is to simply resuspend in TE + RNAse at the last step and leave it at room temperature for 15mins-1hr. ...
Hi Sigrid, if you just want to concentrate the protein in the solution you could also try it by using a SpeedVac.

The affinity of metal chelates for amino acids, such as histidine, is widely used in purifying proteins, most notably through six-histidine `tails. We have found that metal affinity interactions can also be applied to separation of single-stranded nucleic acids through interactions involving exposed purines. Here we describe a metal affinity precipitation method to resolve RNA from linear and plasmid DNA. A copper-charged copolymer of N-isopropyl acrylamide (NIPAM) and vinyl imidazole (VI) is used to purify plasmid from an alkaline lysate of E. coli. The NIPAM units confer reversible solubility on the copolymer while the imidazole chelates metal ions in a manner accessible to interaction with soluble ligands. RNA was separated from the plasmid by precipitation along with the polymer in the presence of 800 mM NaCl. Bound RNA could be recovered by elution with imidazole and separated from copolymer by a second precipitation step. RNA binding showed a strong dependence on temperature and on the ...

We designed a polyethylene glycol precipitation method for detecting retroviral gp70-anti-gp70 immune complexes (gp70 IC) in the circulation of mice. To determine the genetic contribution of NZB and NZW strains to the spontaneous occurrence of circulating gp70 IC in NZB X NZW (B/W)F1 hybrids, we measured these IC in female NZB, NZW, (NZB X NZW)F1 (B/W F1), B/W F1 X NZW backcross, and B/W F1 X NZB backcross mice. The highest amounts of gp70 IC were found in B/W F1 and the lowest in NZW mice, and the order of the average serum levels was B/W F1, B/W F1 X NZB, B/W F1 X NZW, NZB, and NZW. Genetic analyses suggested that two major dominant genes, one from NZB and the other from NZW, are involved in the formation of these gp70 IC. A single dominant gene of NZB strain determines the formation of these IC, and the magnitude is to a great degree modified (intensified) by the NZW gene. In addition, statistical analyses of data obtained in the studies of B/W F1 X NZW backcrosses suggested the presence of ...

PY - 1994/12. Y1 - 1994/12. N2 - The secondary structure content of microparticulate insulin powders produced by the supercritical antisolvent (SAS) precipitation technique was investigated via Raman spectroscopy. Precipitate samples were generated at 25 and 35 °C processing temperatures. Both precipitate samples gave amide I band spectra that were shifted roughly +10 cm−1 relative to the commercial powder. The corresponding secondary structure estimates had significantly increased β‐sheet contents with concomitant decreases in α‐helix contents relative to the commercial protein; the sum of β‐turn and random coil content remained essentially unchanged. The magnitude of the perturbation was slightly greater for the 35 °C sample. Dissolution of the commercial powder and precipitates in 0.01 M ...

Scale deposition is inhibited with a new scale inhibitor precipitation squeeze method wherein inhibitor solution is injected at a higher first pH into a subsurface brine producing formation. Thereafter, the solution is subjected to a fluid or substance which lowers the higher first pH of the scale inhibitor solution to a lower second pH, thereby causing precipitation of scale inhibitor in the formation. The scale inhibitor is characterized by the fact that the scale inhibitor exhibits a significant solubility decrease between the higher first pH and the lower second pH. The method of this invention, therefore, is based on decreasing the pH the scale inhibitor solution to deposit the scale inhibitor and does not use prior art divalent cation precipitation methods to precipitate inhibitors. This invention lessens the chances of formation damage or plugging. The preferred scale inhibitors are the amine phosphonates of a given general structure. The most preferred scale inhibitors are ethylenediaminetetra

The ultimate, indivisible unit of matter. It is distinguished from the corpuscle, also the ultimate, indivisible unit of matter, by a closer resemblance to the atom, also the ultimate, indivisible unit of matter. Three great scientific theories of the structure of the universe are the molecular, the corpuscular and the atomic. A fourth affirms, with Haeckel, the condensation of precipitation of matter from ether -- whose existence is proved by the condensation of precipitation. The present trend of scientific thought is toward the theory of ions. The ion differs from the molecule, the corpuscle and the atom in that it is an ion. A fifth theory is held by idiots, but it is doubtful if they know any more about the matter than the others ...

Microbial induced carbonate precipitation (MICP) is a common occurrence of geochemistry influences in many fields, such as biological, geographical, and engineering systems. However, the processes that control interactions between carbonate biomineralization and biofilm properties are poorly understood. We develop a method for real time, in situ and nondestructive imaging with confocal scanning microscopy. This method provides a possible way to observe biomineralization process and the morphology of biomineralized deposits within biofilms. We use this method to show calcite biominerals produced by Pseudomonas aeruginosa biofilms which extremely change biofilm structures. The distribution of calcite precipitation produced in situ biomineralization is highly heterogeneous in biofilms and also to occur primarily on the bottom of biofilms. It is distinct from those usual expectations that mineral started to precipitate from surface of biofilm. Our results reveal that biomineralization plays a comprehensive

Heavy metals precipitation The principle technology to remove metals pollutants from wastewater is by chemical precipitation. Chemical precipitation includes two secondary removal mechanisms, coprecipitation and adsorption . Precipitation processes are characterized by the solubility of the metal to be removed. They are generally designed to precipitate trace metals to their solubility limits and obtain additional removal by coprecipitation and adsorption during the precipitation reaction.

A comprehensive review and extension of the theoretical bases for the measurement of the characteristics of rain and snow with vertically pointing Doppler radar are presented. The drop size distribution in rain can be computed from the Doppler spectrum, provided that the updraft can be estimated, but difficulties are involved in the case of snow. Doppler spectra and their moments are computed for rain by using various power law relations of fall speed υ versus particle diameter D and an exponential fit to the actual fall speed data. In the former case, there is no sharp upper bound to the spectra and all the spectral moments increase with rainfall rate R without limit; in the latter case, there is a sharp upper bound of the spectra corresponding to the limiting terminal velocity of raindrops, and the spectral moments approach an asymptote. Accordingly, the power laws are useful approximations over only limited ranges of precipitation rate. A comparison of theoretical and experimental mean ...
A number of purification techniques such as adsorption, centrifugation, chromatography, extraction, distillation, filtration, precipitation etc. to name a few, are commonly used for the purification. However, due to a constant need of purification of even more complex crude mixtures, be it reaction mixtures, various proteins and DNA from cell extracts or medicinal compounds and fragrances from plant extracts, scientists needed to consistently develop new and improved techniques of purification. One such great advancement in the field of chromatography was the development of affinity chromatography. It revolutionized the field of bioseparations technology, and the dream of single stage purification of complex biological substrates such as proteins, enzymes, co-enzymes, DNA, RNA etc. was realized. Development of various precipitation techniques involving phase tags, acid-base induced precipitation, host-guest interactions, chemoselective precipitation etc. further simplified purification procedures for
Construction of clones and HEK transfection.α0 (cSlo1, GenBank numberU23821) was cloned by homology screening of a chick cochlear cDNA library (Jiang et al., 1997). Chimeric splice variant clones were constructed by inserting exon-present RT-PCR products into the α0 cDNA by ligation of the restricted products. Final sequence of each chimeric construct was confirmed using primers upstream of the added exons. Plasmids for expression in the mammalian HEK293 cell line were created by packaging the full-length cDNA clone into pcDNA 3.1 (Invitrogen, Carlsbad, CA). Before recording, cells were propagated in DMEM (Life Technologies, Gaithersburg, MD) supplemented with 10% fetal bovine serum (Life Technologies). Cells were transfected using calcium phosphate precipitation. The mixture included green fluorescent protein (GFP) cDNA (pGreenLantern, Life Technologies) to label transfected cells. Recordings were made 24-48 hr after transfection.. The quail β subunit of the slo protein (GenBank accession ...

Inconel© 625 is a Nickel-base superalloy used in aerospace industry as turbine shrouds, spray bars, hydraulic tubing, armoring and thrust reversers systems [1]. One reason of its use is its high mechanical properties at high temperature. Inconel© 625 is strengthened by precipitation of γ″ phase, tetragonal Ni 3 Nb [1]. Since dislocations can influence precipitation [2], the precipitation of γ″ in Inconel© 625 was studied in samples submitted to cold straining to induce different dislocation contents before precipitation heat treatment.

The sensitivity of warm- and mixed-phase orographic precipitation to the aerosol background with simultaneous changes in the abundance of cloud condensation nuclei and ice nucleating particles is explored in an idealized, two-dimensional modeling study. The concept of precipitation susceptibility dlnP/dlnN, where P is the precipitation mixing ratio and N the cloud droplet number, is adapted for orographic clouds. Precipitation susceptibility is found to be low because perturbations to different precipitation formation pathways compensate each other. For mixed-phase conditions, this in particular means a redistribution between warm and cold pathways. The compensating behavior is described as a consequence of a balance equation for the cloud water along parcel trajectories that constrains the total precipitation formation to match the drying from condensation and vapor deposition on ice-phase hydrometeors caused by the mountain flow. For an aerosol-independent condensation rate (saturation ...

Precipitation is usually classified as convective or stratiform. Convective precipitation is normally associated with cumulus and cumulonimbus clouds within which a significant vertical velocity keeps the cloud droplets inside the cloud, enhancing their growth until the vertical currents are not able to counteract the force of gravity any longer and precipitation is produced. Stratiform precipitation is produced mainly by nimbostratus and sometimes by stratocumulus/altocumulus. In these clouds the vertical velocity is lower than inside the convective clouds, and it cannot prevent cloud droplets from falling earlier. The result is a smaller raindrop in these clouds (Houze, 1993).. Drop Size Distribution (DSD) at ground level will depend, among other parameters, on the type of precipitation. It is known that DSD varies both spatially and temporally (Ulbrich, 1983), not only within a specific storm type but also across differing storm types and climatic regimes. It can be characterized by three ...

A mathematical model characterizing the operation of the benzene stripping columns in the In-Tank Precipitation (ITP) process has been developed. The model was verified using operations data of two stripping columns, and the model predicted reasonable, conservative values of the height of a transfer unit (HTU) and outlet solute concentrations. The model was applied to predict general operating efficiency of the ITP strippers, and predictions indicate that the stripping columns will be able to satisfy benzene removal requirements. 12 refs ...
