These BM-40 ELISA kits are immunodetection tools for measuring the levels of BM-40 in biological samples. BM-40 is an alias of the human SPARC gene, which encodes the protein, secreted protein acidic and cysteine rich. Notably, BM-40 is known to play a role in the regulation of angiogenesis, among other functions. The SPARC protein is described to be 303 amino acid residues in length and 34.6 kilodaltons in mass. Its subcellular localization is in the extracellular matrix and is secreted. This protein is known to be glycosylated. Other names for this target antigen include OI17.
