Anti-LAMB4 antibodies are used in the immunodetection of the protein laminin subunit beta 4. In humans, the canonical protein has a reported length of 1761 amino acid residues and a mass of 193.5 kDa. Its subcellular localization is in the extracellular matrix and is secreted. Up to 3 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. LAMB4 is known to be involved with cell adhesion. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include laminin beta-1-related protein. LAMB4 gene orthologs have been reported in the mouse, frog and chicken species. ELISA, Western Blot, Immunocytochemistry, and Immunohistochemistry are common applications for LAMB4 antibodies.
