Mouse IgG1 ELISA Kit

Immunoglobulin G (IgG) is the most prevalent protein found in the human serum. About 10–20% of plasma protein accounts for IgG. IgG1 is the major Ig isotype in murine serum. It resembles human IgG4 functionally. Murine immunoglobulin G1 (IgG1) is capable of blocking the complex formation of IgG2a, IgG2b, and IgG3 with C1q. C1q-mediated complement activation by IgG2a can be blocked by murine IgG1. Because of their likely inhibitory influence on both complement and classical Fcγ receptor (FcγR) activation, murine IgG1 may have the greatest inhibitory capacity toward all other IgG types. The antibody pair provided in this kit recognizes mouse IgG1.
