One-step purification of murine IgM and human alpha 2-macroglobulin by affinity chromatography on immobilized snowdrop bulb lectin.
A new mannose-specific plant lectin (GNA) isolated from the snowdrop bulb was immobilized on Sepharose 4B and employed for the purification of certain glycoproteins with high-mannose type glycan chains. Murine IgM bound tightly to this column and was eluted with 0.1 M methyl alpha-D-mannoside whereas bovine and murine IgG were not bound. When a murine hybridoma serum containing IgM monoclonal a...
متن کاملEvaluation and comparison of affinity chromatography and precipitation– based methods on purification of recombinant streptokinase
Background: Increase of protein purity is a serious challenge in the production of recombinant therapeutic proteins. For this purpose, several strategies have been employed to purify the target protein, among which the affinity chromatography-based purification methods and tagged proteins such as Ni-NTA are common and but costly. Therefore column-free purification techniques, such as using elas...
متن کاملSingle step purification of ovine luteinizing hormone by affinity chromatography.
Affinity chromatography has been applied to the problem of specifically removing luteinizing hormone from sera used to supplement tissue culture media. Horse or fetal calf sera, passed through a column of an anti-luteinizing hormone immunoglobulin fraction linked covalently to agarose, were specifically depleted in their content of luteinizing hormone as seen by radioimmunoassay and by their ef...
متن کاملPurification of egg yolk immunoglobulins. A two-step procedure using hydrophobic interaction chromatography and gel filtration.
A two-step chromatographic procedure was developed for the isolation and purification of hen IgY antibodies from egg yolk. The antibodies were completely separated from vitellin and lipids by hydrophobic interaction chromatography followed by gel filtration. Almost no residual yolk proteins, no immunoglobulin aggregates, and no antibody fragments could be detected in the final extract. Moreover...
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...
