General description

The gene LAMA2 (laminin-2) encodes a protein belonging to a large family of heterotrimeric glycoproteins called laminins. It contains a large globular C-terminal domain that binds to dystroglycan and integrin α7β1 cell receptor specific for myofibers. The amino terminal domain associates with other laminins during the formation of protein meshwork that is involved in the basal membrane supramolecular assembly. The gene is mapped to human chromosome 6q22.33.

Physical form

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


The epitope recognized by the antibody resides in the N-terminal portion of the α2 chain of laminin.

Preparation Note

Purified from the culture supernatant of hybridoma cells grown in a bioreactor.


Anti-Laminin-2 (α-2 Chain) antibody, Rat monoclonal has been used in immunofluorescence and immunohistochemistry.

Biochem/physiol Actions

Laminins are glycoproteins that function in extracellular matrix architecture, cell adhesion, differentiation, and neurite outgrowth. Mutations in the gene LAMA2 (laminin-2) leading to either partial deficiency or complete absence of laminin α2 have been associated with limb-girdle muscular dystrophy (LGMD), characterized by severe, early-onset congenital muscular dystrophy to mild, later childhood-onset limb-girdle type muscular dystrophy, hypotonia with muscle weakness at early infancy, poor spontaneous movements with contractures of the large joints, and weak cry along with respiratory dysfunction.
