Selective enzyme purification by affinity chromatography.
The purification of proteins by conventional procedures is frequently laborious and incomplete, and the yields are often low. Enzyme isolation based on a highly specific biological property-strong reversible association with specific substrates or inhibitors-has received only limited attention.‘-’ In affinity chromatography, the enzyme to be purified is passed through a column containing a cros...
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 کاملAffinity chromatography with an immobilized RNA enzyme.
M1 RNA, the catalytic subunit of Escherichia coli RNase P, has been covalently linked at its 3' terminus to agarose beads. Unlike M1 RNA, which is active in solution in the absence of the protein component (C5) of RNase P, the RNA linked to the beads is active only in the presence of C5 protein. Affinity chromatography of crude extracts of E. coli on a column prepared from the beads to which th...
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 ...
