Laminin alpha 4 Antibody [Unconjugated]

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

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.

Limitations

Summary

• Application: Other
• Sample Tested: P12 20µm mouse brain frozen sections
• Species: Mouse
• Lot: YLCO120022

Comments

• Comments: A lot of standardisation may be required for the antibody to work.
  good fixation of the tissue may help. for adult tissues, they need to be perfused well in order to achieve good results.
