Anti-LadA antibodies enable researchers to detect and measure the LadA antigen in biological samples. This target is a reported synonym of the LAD1 gene, which encodes ladinin 1. The human version of LadA has a canonical amino acid length of 517 residues and a protein mass of 57.1 kilodaltons. It is reported to be localized in the extracellular matrix and is secreted of cells and widely expressed in many tissue types.
