Description

In Vivo Grade Recombinant HyHEL-10 Mouse IgG2a Isotype Control Antibody

Catalog No.: PA007154.m2a

Background

Naturally synthesized and secreted by plasma B cells, the immunoglobulin G (IgG) antibodies are the most abundant antibody isotypes found in blood and extracellular fluid. There are four IgG subclasses (IgG1, IgG2, IgG3, and IgG4) in humans. IgG antibodies are large molecules of about 150 kDa composed of four peptide chains, two identical heavy chains of about 50 kDa and two identical light chains of about 25 kDa. The four peptides are arranged in a Y-shape tetramer by disulfide bonds formed between the two heavy chains and between a heavy chain and a light chain.
