Monolith weak affinity chromatography for μg-protein-ligand interaction study

Ligand Affinity Chromatography

A simple method for the purification of staphylococcal enterotoxins A (SEA), B (SEB), and C2 (SEC2) from fermentor-grown cultures was developed. The toxins were purified by pseudo-affinity chromatography by using the triazine textile dye "Red A" and gave overall yields of 49% (SEA), 44% (SEB), and 53% (SEC2). The purified toxins were homogeneous when analyzed by sodium dodecyl sulfate-polyacryl...

Monolith immuno-affinity enrichment liquid chromatography tandem mass spectrometry for quantitative protein analysis of recombinant bovine somatotropin in serum

The use of recombinant bovine somatotropin (rbST) to enhance milk production is approved in several countries, but it is prohibited in the European Union. According to EU legislation, it is necessary to confirm positive screening results prior to enforcement. Although adequate screening assays are available nowadays, development of liquid chromatography tandem mass spectrometry (LC-MS/MS) confi...

evidence of human hemoglobin interaction and chorionic gonadotropin hormone: prospects for the use of hemoglobin as ligand in affinity chromatography for the purification of the hormone

the purification of biomolecules is a necessary step in many biochemical researches. in this regard, developments of convenient, specific and low cost methods of purification are of particular interest. given the human hemoglobin (hb) affinity toward some charged carbohydrates, interaction of this molecule with human chorionic gonadotropin (hcg) which is a glycoprotein hormone containing sialic...

Protein Purification by Affinity Chromatography

The preparation of a number of agarose and polyacrylamide bead derivatives useful in the purification of proteins by afhnity chromatography is described. These techniques permit (a) the attachment of ligands to the gel through extended hydrocarbon chains which place the ligand at varying distances from the gel matrix backbone; (b) the covalent attachment of ligands to agarose or polyacrylamide ...
