Purified Mouse IgG, 20 mg
Purified from pooled mouse serum. 99% purity. No trace of IgA, IgM or non-immunoglobulin serum proteins

IgG2B (Kappa) MPOC 195, mouse myeloma, purified, 1 mg
Mouse IgG2b (j) is purified from clarified mouse MOPC 195 ascites using multi-step procedures which may include salt fractionation, gel filtration, ion-exchange chromatography, affinity chromatography and immunoabsorption. The product is dialyzed into 0.02 M Tris, 0.15 M sodium chloride, pH 8.1, filtered through a 0.22 µm filter and vialed.

IgG, rat, 100 mg
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.

Proline Specific Endopeptidase (From Flavobacterium Meningosepticum), 50 U
Proline Specific Endopeptidase specifically cleaves peptide bonds on the carboxy side of proline residues. Much slower hydrolysis is observed on the carboxy side of alanine residues. This enzyme is very close, in its properties, to a post-proline cleaving enzyme. The substrates have been found to have the general structure Y-Pro-X, where Y is a peptide or N-protected amino acid and X may be an amino acid, peptide, amide or ester.
