Anti-LAM5 antibodies enable researchers to detect and measure the LAM5 antigen in biological samples. This target is a reported synonym of the LAMB3 gene, which encodes laminin subunit beta 3. This protein is known to function in brown fat cell differentiation and cell adhesion, among other biological roles. The human version of LAM5 has a canonical amino acid length of 1172 residues and a protein mass of 129.6 kilodaltons. It is reported to be localized in the extracellular matrix and is secreted of cells and notably expressed in many tissues, such as the breast, tonsil, and appendix. Other names for this target antigen include AI1A, BM600-125KDA, and JEB1A.
