Ig Light Chain (human) Rabbit Monoclonal Antibody

Immunoglobulins are members of the glycoprotein superfamily that play a central role in the adaptive immune response.{28520} They are produced by B cells and later secreted by plasma cells as antibodies.{55225} Immunoglobulins are composed of two heavy chains of approximately 50 kDa each and two light chains of approximately 25 kDa each.{28520} The heavy chains are linked together by disulfide bonds to form an Fc region and also combine with the light chains to form the Fab region, which mediate receptor and antigen binding, respectively.{55171} Mammalian immunoglobulins contain either Ig? or Ig? light chains, each of which are composed of a constant and variable domain.{28687} The ratio of Ig? to Ig? light-chain containing antibodies varies between species, with ratios of 20:1, 2:1, and 1:20 in mice, humans, and cattle, respectively. Ig? and Ig? free light chains (FLCs) are produced during immunoglobulin synthesis, and accumulation of these FLCs is associated with various disorders, including light-chain deposition disease, multiple myeloma, rheumatoid arthritis, diabetic nephropathy, and systemic lupus erythematosus (SLE).{55225,55232,53885} Cayman's Ig Light Chain (human) Rabbit Monoclonal Antibody (Clone RM129) be used for ELISA, flow cytometry (FC), immunocytochemistry (ICC), and immunohistochemistry (IHC) applications. The antibody recognizes both the Ig? and Ig? light chains from human samples.
