[MOPC 104E]
These myeloma proteins are purified from ascites by a combination of salt precipitation, ion exchange and bioaffinity chromatography. Purified proteins are dialyzed into 0.02M Tris, 0.14M sodium chloride, pH 8.1. Product is adjusted to 1.0 mg/ml, filtered, vialed, and stored frozen at -70°C. Product is shipped on dry ice.

Lyophilized Clarified mouse myeloma ascites IgG2b (j) MOPC 195.

[MOPC 21]
Ascites fluid, collected from Balb/c mice which carry plasmacytomas subcutaneously, are clarified by centrifugation and filtration. It is dialyzed, adjusted to yield at least 5 mg of immunoglobulin, then vialed and lyophilized. Clarified ascites are tested for immunoglobulin by immunoelectrophoresis using antisera specific for the particular type and isotype. Approximately 10% of the total protein is immunoglobulin (including trace levels of the host's immunoglobulins), 80% is albumin, and 10% is complement and other proteins.

Lyophilized rat IgG with buffer salts.

Purified rat IgG may be used as a reference antigen, standard, blocking agent, or coating protein in a variety of immunoassays including ELISA, dot immunobinding, western immunoblotting, immunodiffusion, and immunoelectrophoresis. Other applications include starting materials for the preparation of immunogens and solid phase immunoadsorbents. Rat IgG was used as isotype control in flow cytometry and injected into mice to induce tolerance against rat IgG.

Lyophilized rabbit IgG F(ab')2 with buffer salts.

Lyophilized rabbit IgG with buffer salts. Rabbit IgG is purified from pooled rabbit serum using multi-step procedures which may include salt fractionation, gel filtration, ion-exchange chromatography and immunoabsorption.
