General description

Laminin is a ubiquitous non-collagenous connective tissue glycoprotein that is a major constituent of basement membranes. Laminins are extracellular matrix proteins. The LAMA1 (laminin subunit α 1) gene is mapped to human chromosome 18p11. The antibody is isolated from antiserum by immunospecific methods of purification. Antigen specific isolation removes essentially all rabbit serum proteins, including immunoglobulins that do not specifically bind to laminin.

Specificity

Specificity of the anti-laminin antibodies is determined by indirect immunofluorescent labeling of formalin-fixed, paraffin-embedded human or animal tissue sections, and by dot blot immunoassay. By indirect immunofluorescence the antibody demonstrates specific basement membrane staining of enzymatically unmasked human and animal tissue. In the dot blot immunoassay the rabbit anti-laminin antibody reacts with laminin but not with fibronectin, vitronectin, collagen IV, or chondroitin sulfate types A, B, and C. The affinity isolated antibody to laminin will react with laminin of human, mammal, avian, reptilian, and amphibian sources.

Immunogen

Laminin isolated from the basement membrane of Englebreth Holm-Swarm (EHS) mouse sarcoma.

Application

Anti-Laminin antibody has been used in immunohistochemical staining and immunohistochemistry.
Rabbit Anti-Laminin antibody may be used in immunohistochemistry for marking blood vessel walls in different species, classification of various disease processes involving basement membranes, identification of the origin of human tumors and their classification, and for distinguishing between non-invasive and invasive lesions. The antibody may be used to monitor levels of laminin in biological fluids and for experimental production of basement membrane lesions in vivo.
A working dilution of at least 1:1,000 was determined by a dot blot immunoassay using laminin at 50 ng per dot.
A working dilution of at least 1:25 was determined by indirect immunohistology using formalin-fixed, paraffin-embedded human and animal tissues.

Biochem/physiol Actions

LAMA1 (laminin subunit α 1) is involved in several diseases like cancer, infections, inflammatory diseases and autoimmune disorders. Mutations in LAMA1 result in cerebellar dysplasia and cysts with and without retinal dystrophy. LAMA1 is also essential in the assembly of basement membrane and early growth of embryo.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 1% BSA and 15 mM sodium azide.

Storage and Stability

For continuous use, store at 2-8 °C for up to one month. For extended storage, the solution may be frozen in working aliquots. Repeated freezing and thawing, or storage in "frost-free" freezers, is not recommended. If slight turbidity occurs upon prolonged storage, clarify by centrifugation before use.
