Gene Information

General description

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.

Specificity

Monoclonal Anti-Laminin antibody specifically recognizes Laminin from human, feline and porcine origin.

Immunogen

purified Laminin from human Placenta

Application

Monoclonal Anti-Laminin is recommended to use in various immunochemical assays, including immunohistochemistry, immunoblotting (~850 kDa), immunofluorescence, Enzyme linked immunosorbent assay (ELISA) and electron microscopy.

Biochem/physiol Actions

Laminins contribute to the structure of the extracellular matrix (ECM). It also plays a major role in the regulation of variety of cellular processes, such as the rates of cell proliferation, differentiation, adhesion, migration, cell shaping, phenotype stability and resistance to apoptosis. Laminin polymers forms supramolecular network with collagen IV polymers through heparan sulfate proteoglycan and by nidogen (entactin) and plays an important role in the basement membrane (BM) stability. In mouse, mutations in the gene is associated with the development of muscular dystrophy.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Storage and Stability

Store at –20°C. For continuous use, store at 2–8°C for up to one month. For extended storage, freeze in working aliquots. Repeated freezing and thawing is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilution samples should be discarded if not used within 12 hours.
