General description

IgM antibodies are present as pentamers in the serum and are produced in response to antigens IgM, κ from murine myeloma is produced by TEPC 183 tumor line introduced subcutaneously in BALB/c mice.
IgM is a highly conserved antibody in vertebrates and is expressed early during immune response. It is secreted by peritoneal B cells.

Specificity

The TEPC 183 tumor line is pristine-induced plasmacytoma-originated and carried subcutaneously in BALB/c mice. The hapten binding specificity of the TEPC 183 line has not been determined. It specifically recognizes mouse IgM. Identity and purity of the immunoglobulin is established by immunoelectrophoresis.

Application

IgM, Kappa from murine myeloma has been used in:
  • sandwich enzyme linked immunosorbent assay (ELISA)
  • flow cytometry
  • dot-immunobinding assay

Biochem/physiol Actions

IgM plays a key role in the engulfing of apoptotic cells. A reduction in serum IgM levels leads to increased autoimmune response and higher risk for infections. IgM displays polyreactive and autoreactive functionality. It plays a key role in tissue homeostasis by mediating clearance of tissue based molecules. IgM has sites for N-linked glycosylation, with sugars namely, mannose, galactose, N-acetyl glucosamine and sialic acid. IgM linked agarose resins have been tested for efficient conjugate binding.

Physical form

Solution in 0.05 M Tris, 0.5 M sodium chloride, pH 8.0, containing 0.02% sodium azide
