The basal lamina contains Collagen Type IV, proteoglycans, and glycoproteins. Laminin is a high molecular weight (850 kDa) oligomer, consisting of three different chains (α, β, and γ) joined by disulfide bonds. The structure of laminins include two helical domains (I & II) at the COOH-terminal, a laminin IV domain, multiple EGF-like repeats, and a laminin globular domain (G), as well as an N-terminal domain VI. Domains IV and VI are the binding sites for collagen and heparan sulfate, respectively. Several isoforms have been identified for the genes of each chain. Laminin γ1 (laminin B2) contains 14 glycosylation sites and 12 cysteine repeat domains. The expression of the Laminin subunits is found in the basal lamina of tissues. Here, the protein interacts with other extracellular matrix components to mediate cell attachment, migration and organization during embryonic development.

Western blot image of human MDA-MB-231 cells (lanes 1-3). The blot was probed with mouse monoclonal anti-Laminin γ1 subunit (LM5971) at 1:500 (lane 1), 1:1000 (lane 2), and 1:2000 (lane 3).

Immunocytochemical labeling of laminin γ1 subunit in aldehyde fixed and NP-40 permeabilized human NCI-H446 lung carcinoma cells. The cells were labeled with mouse monoclonal anti-laminin γ1 subunit (LM5971). The antibody was detected using goat anti-mouse DyLight® 594.

Clone (M597) was generated from a recombinant protein containing amino acids in domain IV of human laminin γ1 subunit. This sequence is highly conserved in mouse and rat laminin γ1 subunits.
