They are usually colourless crystalline solids at room temperature with relatively high melting points for molecules of their relative molecular mass and usually highly or moderately soluble in water. (docbrown.info)
In the second type of C7 deficiency, the quantity of C7 is diminished and the protein exhibits an altered isoelectric point. (lu.se)
S(0)s determined using SAXS and SLS for the different MAbs are then compared, based on the individual isoelectric point and net charge distribution over the surface for each MAb, to gain a deeper understanding of how these parameters affect protein-protein interactions at high concentrations. (lu.se)
HiRIEF fractions with the most acidic isoelectric points are enriched in multiply phosphorylated peptides, which represent 18% of all the phospho-peptides detected in the pH range 2.5-3.7. (scilifelab.se)
Enzyme1
Seven kinds of enzymes with various isoelectric points (pI) were immobilized on the Fe2O3/ HA composite particles in buffered solution adjusted at pH = 7.40 or pH = 10.0, 36.5 °C. Effects of the enzyme pI and the solution pH on the immobilization were investigated. (elsevierpure.com)
This was symbolically termed torsade de pointes, or "twisting of the point" about the isoelectric axis, because it reminded the authors of the torsade de pointes movement in ballet. (medscape.com)
The third simple way of These limits are even more relevant assessing the ventricular axis consists of the when considering that the diagnosis of location of the most isoelectric limb lead1. (bvsalud.org)
Particles3
Then sonication (200 kHz or 28 kHz) was applied to adjust pH to the isoelectric points and separated particles from solutions by still-standing and spontaneous precipitation. (nih.gov)
The sonication of green tuff and andesite suspensions at 200 kHz changed the pH to the isoelectric zone despite the pH buffering effect of eluted alkali earth metals, and successfully precipitated the particles. (nih.gov)
On the contrary, the sonication of these suspensions at 28 kHz failed to adjust pH to the isoelectric zone, and the particles did not precipitate. (nih.gov)
Acids1
DNA recovery from agarose gel: As a result of this enzymatic degradation the viscosity and gelling ability of the native low melting point agarose is eliminated liberating the nucleic acids. (worthington-biochem.com)
The isoelectric point (IEP) of ZrB2 was ~4.5, which was close to the previously reported values of ~4.7. (mis-asia.com)
Close to the isoelectric point of 6, IFNα-2a forms insoluble aggregates which can be prevented by adding salt. (lu.se)
Positive1
3. Positive findings in a cerebrospinal fluid (CSF) specimen (isoelectric focusing evidence of oligoclonal bands and/or elevated immunoglobulin (Ig) G index) [If a recent CSF sample or results from a previous CSF test from each patient is not available, this data will be considered missing information]. (who.int)
The isoelectric point (pI, pH(I), IEP), is the pH at which a molecule carries no net electrical charge or is electrically neutral in the statistical mean. (wikipedia.org)
Determining relative protein expression levels by conventional two-dimensional electrophoresis requires isoelectric focusing, SDS-polyacrylamide gel electrophoresis, staining, fixing, densitometry, and careful matching of the same spots on two or more gels. (biomedcentral.com)
Isoelectric point of protein moves out to acid direction in presence of NaCl, isoelectric point of protein moves out to alkaline direction in presence of KCl. (ifmo.ru)
Density1
Important discrepancies in isoelectric points (pI) of beta-lactamases were observed depending on the experimental procedure used for their determination: isoelectric focusing (IEF) in sucrose density gradients or analytical IEF in thin-layer polyacrylamide gels (PA). (nih.gov)
Proteomics1
Proteomics of BPs reaches a point where the information gained over the last decade, and the one that has to be acquired, should be transferred into transfusion science. (medscape.com)
Surface1
The surface charge of amphibole minerals in potable water was negative and, in common with most other silicate minerals, the isoelectric point of amphibole asbestos fibers is in the ph range 4 to 6. (cdc.gov)
