Laminin alpha 4 in Mouse Embryo. Laminin alpha 4 was detected in immersion fixed frozen sections of mouse embryo (13 d.p.c.) using Goat Anti-Mouse Laminin alpha 4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3837) at 3 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to membranes in blood vessels in CNS. View our protocol for Chromogenic IHC Staining of Frozen Tissue Sections.

Background: Laminin alpha 4
Laminins are heterotrimeric glycoproteins and are major components of the basement membrane. Each laminin is comprised of a single alpha, beta, and gamma chain that heterotrimerize via their coiled-coil domains to form a large cruciform-shaped molecule. Mature Laminin alpha 4 is a subunit of Laminin 411, Laminin 421, and Laminin 423. Mature Laminin alpha 4 is a 1792 amino acid (aa) residue protein that has a Laminin N-terminal domain, four Laminin EGF-like domains, the coiled-coil domain, and five C‑terminal tandem Laminin G-like domains. The G-like domains contain binding sites for integrin, heparin, and dystroglycan. Within the region used as immunogen, mouse Laminin alpha 4 shows 91% and 97% aa sequence identity with human and rat Laminin alpha 4, respectively.
