Monoclonal anti-laminin antibody (mouse IgG1 isotype) is derived from the LAM-89 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from a mouse immunized with purified laminin from human placenta. Monoclonal anti-laminin antibody specifically recognizes laminin from human, feline and porcine origin. The antibody shows reactivity with laminin and specifically staining basal membrane of blood vessels, epithelium, nerve and muscle fiber. Monoclonal anti-laminin shows no reaction with collagen IV, fibronectin, vitronectin and chondroitin sulfate type A, B or C. Laminins are complexed extracellular glycoproteins which assemble the basal components of the basement membrane (BM). Each laminin is a heterotrimer (~850kDa) comprising of an α (~400kDa), β (~200kDa) and γ (~200kDa) chains all held together by disulfide bonds.
