Merck, SAB3700041-2ML, Anti-Bovine IgM (μ-chain specific) antibody produced in rabbit

General description
Antibody format: Antiserum
During the B-cell development, IgM (immunoglobulin M) is the first expressed antibody. It is present as a monomer on the surface of naive B cells. Antigenic stimulation and upon maturation, the monomeric IgM units (190kDa), are linked by disulfide bonds to form a pentameric immunoglobulin structure. It also but rarely forms a hexameric structure. The pentameric IgM is linked by a disulfide bond, a polypeptide chain and a J-chain. The μ -chain consists of five domains- VH, Cμ1, Cμ2, Cμ3 and Cμ4.
Immunogen
Bovine IgM mu heavy chain
Biochem/physiol Actions
The J-chain of the multimeric IgM (immunoglobulin M) structure is responsible for secretion at the mucosal surfaces. The pentameric form of IgM, has a greater affinity towards antigens (with multiple repeating epitopes) compared to the monomers. IgM pentamer enables better opsonization of antigens for destruction and fixing complement.
This product was prepared from monospecific antiserum by a delipidation and defibrination. Assay by immunoelectrophoresis resulted in a single precipitin arc against Bovine IgM and Bovine Serum. No reaction was observed against Bovine IgG F(ab′)2 or Bovine IgG F(c).
