The common rabbit IgG isotype has a molecular weight of 150 KD, with two heavy chains (about 50 KD each) and two light chains (about 25 KD each) under the non-reducing condition. Under the reducing condition, the molecular weights are 50 and 25 kD for …Jan 1, 2013 · MAb-A is a recombinant IgG1 subtype humanized monoclonal antibody produced in CHO cells. Common antibody high molecular weight size variants include dimer, trimer, and tetramer. MAb-A lots produced from different clones and production scales all contain an unusual SEC peak that elutes between MAb-A monomer and dimer. Antibody molecules consist of two identical heavy chains and two identical light chains, which consequently give the antibody two antigen-binding sites.
A single antibody molecule contains either κ light chains or λ light chains, but never both. Each heavy chain has a molecular weight of ~50,000 daltons and consists of a constant and variable region.Jul 29, 2017 · Structure and origin. All currently clinically used therapeutic antibodies are immunoglobulin G (IgG) monoclonal antibodies (mAbs)1 and possess the same basic structure (Figure 1): 1): they are large heterodimeric protein molecules with a molecular weight of ∼150 kDa and are composed of four polypeptide chains, two identical heavy chains (50 kDa), and two light chains (25 kDa). Nov 1, 2013 · Molecular weight determination. The molecular weight (MW) of species present in a mAb-X reference standard and samples enriched in the shoulder or monomer species of mAb-X was determined by SE-HPLC with MALS (Table 1). The average MW of the monomer was 152.0 kDa, which is 3.6% above the theoretical MW of 146.7 kDa. ….
