Protein A is a highly stable surface receptor which is capable of binding the Fc portion of immunoglobulins, especially IgGs, from a large number of species. Each protein A molecule can bind 2 molecules of IgG, allowing the formation of a precipitate. Protein A may be coupled to a wide variety…

The total protein is determined using the Biuret procedure, with bovine albumin as the standard. Each vial is overfilled by approximately 10 percent so that a minimum of 20 mg of rat IgG is obtained upon reconstitution. Rat IgG is purified from pooled rat serum using multi-step procedures…

Product is the lyophilized powder of human hemoglobin and buffer salts. Human hemoglobin is purified from human red blood cells using multi-step procedures which may include salt fractionation, gel filtration, ion-exchange chromatography and immunoabsorption. The product is dialyzed into 0.01M…

The total protein is determined using the Biuret procedure, with bovine albumin as the standard. Each vial is overfilled by approximately 10 percent so that a minimum of 20 mg of mouse IgG is obtained upon reconstitution. Mouse IgG is purified from pooled mouse serum using multi-step…

All blood products should be treated as potentially infectious. The total protein is determined using the Biuret procedure, with bovine albumin as the standard. Each vial is overfilled by approximately 10 percent so that a minimum of 20 mg of monkey IgG is obtained upon reconstitution. Monkey…

Protein A is a recombinant Fc-binding protein from Staphylococcus aureus, Cowan strain-1 gene. The product is a carboxy truncated material containing 301 amino acid residues. The non-binding regions have been removed to minimize potenial steric interference. Protein A may be conjugated with…
