eng] The ion-exchange chromatography is a technique used to separate the milk whey proteins ß-Lactoglobulin A and B. These proteins are very important to obtain different products for the food industry. From these proteins, amounts of important compounds for the biotechnology industry can be obtained, so it is important to separate them correctly and with the most purity possible. The installation to make this separation is a continuous system made up four ionexchange columns. First of all, it is necessary characterized the columns that will be used. The porosity (¿) and the capacity (¿) of the columns are the two first parameters that should be calculated. To obtain these parameters is not necessary work with the proteins; they are calculated using solutions of salt (Sodium Nitrate) and eluent made up this salt, buffer (Bis Tris Propane) and Hydrochloric acid. The installation used is made up four pumps, columns and the UV Sensor. With this, the concentration of the solutions that are driven ...

A retention model is derived for inorganic cations eluted from cation-exchange columns with eluents containing a single competing cation and a complexing ligand. This model is evaluated using divalent solute cations and a low-capacity fixed-site cation-exchange column, and good agreement is obtained between theoretical and experimental results both for simple cation exchange and also when complexation effects are present. Sodium ions added to the eluent during pH adjustment were found to contribute significantly to the elution of solute cations and should be included in all calculations using the retention model. Retention characteristics were also studied for an ion-interaction chromatographic system using a C18 column, octanesulfonic acid as the ion-interaction reagent, and oxalate as the complexing ligand in the eluent. Experimental data for this system did not show close agreement with the ion-exchange retention model. Discrepancies are attributed to variations in the ion-exchange capacity ...

The pI (iso-electric point) is the pH at which the protein (or other molecule), overall has a net zero charge. As @Chris points out, the buffer you are using will change the pH the protein finds itself in. This will change the charge of the protein. In ion exchange chromatography, there are charged chemical groups on the resin and these can cause a protein to be retained on the resin if the protein is complementary (opposite charged) to the resin.. So if you have a protein with a pI of 5 say, it would neutral with the presence of excess H+. This implies that the protein has an overall negative charge. A cationic resin would tend to retain this protein in a pH 7 buffer. I hope that makes sense. In most cases, ion exchange chromatography is used when most of the protein is separated out and there are a few proteins (maybe a couple of hundred) mixed together. It can get tricky if you see that the protein is mixed in with something that is also negatively charged. In that case you might change the ...

A commercially available 4.6 mm id×50 mm polymethacrylate-based monolithic strong anion exchange column (ProSwiftTM SAX-1S) designed for the separation of proteins has been successfully used to separate small inorganic anions in the presence of a seawater sample matrix. Using a hydroxide eluent with suppressed conductivity detection the ion exchange capacity of this column declined over time; however, using KCl as the eluent, the column performance was stable with a capacity of 530 {micro}equiv. for nitrate. The optimum conditions for the separation of iodate, bromate, nitrite, bromide and nitrate were assessed by constructing van Deemter plots using 1.00 and 0.100 M KCl. Efficiencies of up to 26 700 plates/m were recorded using 1.00 M KCl, at a flow rate of 0.20 mL/min but iodate was not baseline resolved from the void peak. By reducing the concentration of the eluent to 0.100 M, efficiencies of up to 39 900 plates/m could be obtained at 0.35 mL/min. By employing a linear gradient ranging from ...
Pyrogenic organic matter (PyOM), the incomplete combustion product of organic materials, is considered stable in soils and represents a potentially important terrestrial sink for atmospheric carbon dioxide. One well-established method of measuring PyOM in the environment is as benzene polycarboxylic acids (BPCAs), a compound-specific method, which allows both qualitative and quantitative estimation of PyOM. Until now, stable isotope measurement of PyOM carbon involved measurement of the trimethylsilyl (TMS) or methyl (Me) polycarboxylic acid derivatives by gas chromatography-combustion-isotope ratio mass spectrometry (GC-C-IRMS). However, BPCA derivatives can contain as much as 150% derivative carbon, necessitating post-analysis correction for the accurate measurement of δ13 C values, leading to increased measurement error. Here, we describe a method for δ13 C isotope ratio measurement and quantification of BPCAs from soil-derived PyOM, based on ion-exchange chromatography (IEC-IRMS). The ...

Hydrophobic Interaction Chromatography is a separation technique that uses the properties of hydrophobicity to separate proteins from one another. In this type of chromatography, hydrophobic groups such as phenyl, octyl, or butyl, are attached to the stationary column. Proteins that pass through the column that have hydrophobic amino acid side chains on their surfaces are able to interact with and bind to the hydrophobic groups on the column. HIC separations are often designed using the opposite conditions of those used in ion exchange chromatography. In this separation, a buffer with a high ionic strength, usually ammonium sulfate, is initially applied to the column. The salt in the buffer reduces the solvation of sample solutes thus as solvation decreases, hydrophobic regions that become exposed are adsorbed by the medium. ...

Isolated neutrophils from healthy donors were used for the isolation of four highly purified forms of myeloperoxidase as determined by spectral (A430/A280 ratio 0.80-0.87) and enzyme-activity measurements. Although the myeloperoxidases exhibited different elution profiles on cation-exchange chromatography, gel filtration indicated similar relative molecular masses. When these forms were assayed for peroxidase and peroxidase-oxidase activities with several substrates, they all exhibited virtually the same specific activities. These results suggest that possible functional differences between the enzymes may be related to differences in their sites of action rather than to differences in enzyme activity. Myeloperoxidase from a patient with chronic myeloid leukaemia also revealed a similar heterogeneity on cation-exchange chromatography. However, this myeloperoxidase contained in addition one form with a lower and one form with a higher relative molecular mass, as indicated by gel-filtration ...
The isolation method is optimized for cultures grown in LB media; other rich media may require increased volumes of Suspension-, Lysis-, and Neutralization Buffer, and an additional wash step. The isolation procedure is suitable for all plasmid sizes; lysates of larger constructs (up to 100 kb) should be cleared by filtration to avoid shearing.. The yield of plasmid DNA preparations is dependent on several parameters, e.g., quality of the bacterial culture growth, amount of used culture suspension for the preparation, plasmid type used etc. As a rule of thumb the typical yield of a high copy number plasmid is about 3 - 5 µg of DNA per ml of original bacterial culture (pUC, pTZ, pGEM in common host strains like XL-1 blue, HB101, JM 109). The typical yield of low copy number plasmids is about 0.2 - 1 µg of DNA per ml of original bacterial culture.. The Genopure kits are supplied with folded filters to eliminate the time-consuming centrifugation step after the alkaline lysis. In approximately 2 ...

In order for pharmaceuticals to be safe, they must be clean of pollutants. Carbon dioxide can be used to make the purification process more environmentally friendly, which may seem paradoxical since carbon dioxide is usually associated with a negative climate impact. However, if carbon dioxide is recovered from other existing processes and if the use of environmentally hazardous organic solvents is reduced, large gains can be made both economically and environmentally.
The charge on the protein affects its behavior in ion exchange chromatography. Proteins contain many ionizable groups on the side chains of their amino acids including their amino - and carboxyl - termini. These include basic groups on the side chains of lysine, arginine and histidine and acidic groups on the side chains or glutamate, aspartate, cysteine and tyrosine. The pH of the solution, the pK of the side chain and the side chains environment influence the charge on each side chain. The relationship between pH, pK and charge for individual amino acids can be described by the Henderson-Hasselbalch equation, which is described in detail elsewhere: In general terms, as the pH of a solution increases, deprotonation of the acidic and basic groups on proteins occur, so that carboxyl groups are converted to carboxylate anions (R-COOH to R-COO-) and ammonium groups are converted to amino groups (R-NH3+ to R-NH2). In proteins the isoelectric point (pI) is defined as the pH at which a protein has no ...
