Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate LAMA2 in samples. An antibody specific for LAMA2 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyLAMA2 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for LAMA2 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of LAMA2 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:Laminin, an extracellular protein, is a major component of the basement membrane. It is thought to mediate the attachment, migration, and organization of cells into tissues during embryonic development by interacting with other extracellular matrix components. It is composed of three subunits, alpha, beta, and gamma, which are bound to each other by disulfide bonds into a cross-shaped molecule.
Laminin subunit alpha-2 is the alpha 2 chain, which constitutes one of the subunits of laminin 2 (merosin) and laminin 4 (s-merosin). Mutations in this gene have been identified as the cause of congenital merosin-deficient muscular dystrophy. Two transcript variants encoding different proteins have been found for this gene.
