Detection of Human Laminin alpha 3/Laminin‑5 by Western Blot.
Western blot shows lysates of human lung tissue. PVDF Membrane was probed with 2 µg/mL of Mouse Anti-Human Laminin alpha 3/
Laminin‑5 Monoclonal Antibody (Catalog # MAB21441) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for Laminin alpha 3/Laminin‑5 at approximately 190 kDa (as indicated). This experiment was conducted under non-reducing conditions and using Immunoblot Buffer Group 1.
Laminin alpha 3/Laminin‑5 in NHEK Human Cell Line. Laminin alpha 3/Laminin‑5 was detected in immersion fixed NHEK human normal epidermal keratinocytes treated with 10ng/mL Recombinant Human TGF-beta 1 (Catalog # 240-B) for 24 hours using Mouse Anti-Human Laminin alpha 3/Laminin‑5 Monoclonal Antibody (Catalog # MAB21441) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to the perinuclear space. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Background: Laminin alpha 3/Laminin-5
Laminins are heterotrimeric, noncollagenous glycoproteins composed of alpha, beta, and gamma chains. Through interactions with integrins, dystroglycan and other receptors, laminins contribute to cell differentiation, cell shape and migration, and maintenance of tissue phenotypes and survival. Laminin alpha 3/Laminin-5, also known as epiligrin, includes alpha 3, beta 3, and gamma 2 subunits. It is abundant in transitional epithelium, stratified squamous epithelia, lung mucosa and other epithelial glands and contributes to initiation and maintenance of epithelial cell anchorage to the underlying connective tissue. Within aa 21‑1713 of the alpha 3 subunit, human and mouse share 77% amino acid sequence identity.
