NIST8671 is intended for research use. It is not intended for animal or human consumption, clinical testing or therapeutic use.

Application

NISTmAb, Humanized IgG1_k Monoclonal Antibody has been used as a standard for testing de novo sequencing algorithm on bottom-up mass spectrometry.

Biochem/physiol Actions

NISTmAb, Humanized IgG1_k Monoclonal Antibody is a recombinant antibody expressed in murine suspension culture. It is a homodimer with two identical light chains and two identical heavy chains linked through inter- and intra- chain disulfide bonds with a molecular weight of 150 kDa. The protein possesses low abundance post-translational modifications including methionine oxidation, deamidation, and glycation. The molecule also has N-terminal pyroglutamination, C-terminal lysine clipping, and glycosylation of the heavy chains.

General description
