Human IgM, Fc5u Native Protein Summary

A full-length protein corresponding to Human IgM, Fc5u.

Source: Human Serum

Human IgM (myeloma) Fc5u fragment has been prepared from Human IgM myeloma protein by digestion with trypsin followed by column chromatography. Purity was assessed by SDS-PAGE and HPLC to be greater than 95%. A single precipitin arc was observed against anti-human IgM Fc5u and anti-human serum when assayed by immuno-electrophoresis at a concentration of 20 mg/ml. No reaction was observed against anti-Trypsin, anti-human IgG F(ab')2, anti-human IgG F(c), anti-human Kappa or anti-human Lambda.

Human IgM (myeloma) FC5U fragment consists of only the u (mu) chain of the Fc fragment. Immunoglobulin M is the largest antibody isotype and the first to be secrected against an initial exposure to antigen. IgM is predominantly produced in the spleen. IgM is formed from covalently linking 5 immunoglobulins together. Due to this large size, IgM is typically isolated to the serum.
