Application
Bovine γ-globulin has been used as an immunological challenge in studies of mechanisms of immunotolerance.4
Bovine γ-globulins were used to study the constituents and pH changes in protein rich hyaluronan solution which affect the biological properties of artificial articular joints.1 It is also used to determine immunoglobulin G in bovine colostrum and milk using direct biosensor SPR-immunoassay.2
General description
Plasma protein fraction rich in antibodies
Packaging
1, 5, 10, 25, 100 g in poly bottle
Preparation Note
Prepared from Cohn Fraction II, III
Biochem/physiol Actions
The γ-G globulins of bovine serum are categorized by anion exchange chromatography, immunoelectrophoresis, zone electrophoresis, ultracentrifugation, and analysis of the products of papain digestion. They have properties similar to analogous components of human serum. This was determined by the methods such as: gel filtration, immunoelectrophoresis, anion exchange chromatography, ultracentrifugation, and reduction with mercaptoethanol. Fast and slow γ-G globulins were classified on the basis of differences in electrophoretic migration rates, chromatographic elution positions, and biological activities (complement fixation). Bovine γ-A was conditionally found in immunoelectrophoretic analyses of serum and chromatographic fractions.3
