Purification of porcine enterokinase by affinity chromatography.
A method is described for the purification of porcine enterokinase by affinity chromatography with p-aminobenzamidine as the ligand. Purification was completed by immunoadsorption with antisera raised to components binding non-biologically to the gel. The final enterokinase preparation was 2.3 times more active than the most active preparation previously described.
متن کاملPurification by Affinity Chromatography
The glycine receptor of rat spinal cord was solubilized with the nonionic detergent Triton X-100 and subsequently purified by affinity chromatography on aminostrychnine-agarose and wheat germ agglutininSepharose. An overall purification of 1950-fold was achieved. Polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulfate and mercaptoethano1 revealed three glycine receptor-asso...
متن کاملPurification and specificity of porcine enterokinase.
Enterokinase (enteropeptidase, EC 3.4.4.8) has been purified from porcine duodenal extracts by chromatography on DEAE-cellulose, carboxymethyl cellulose, Sephadex G-100, and Sephadex G-200. The final product was found to be homogeneous by a number of tests. Its specific activity against trypsinogen (nanomoles of trypsinogen activated per 30 min per mg) was 6550, which represented a 650-fold pur...
متن کاملProtein 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 ...
