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." class="big_lightbox" target="_blank">
HAF016). A specific band was detected for Laminin a4 at approximately 200-220 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1." class="big_lightbox" target="_blank">
CCM017) , using Sheep Anti-Human Laminin a4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7340) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Sheep IgG Secondary Antibody (red; Catalog # NL010) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm and cell surfaces. View our protocol for Fluorescent ICC Staining of Cells on Coverslips." class="big_lightbox" target="_blank">
VC006). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to Golgi apparatus.

7340-A4) supports adhesion in the HT1080 human fibrosarcoma cell line in a dose-dependent manner (orange line), as measured by Calcein AM. Adhesion elicited by Recombinant Human Laminin a4 (5 µg/mL) is neutralized (green line) by increasing concentrations of Sheep Anti-Human Laminin a4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7340). The ND50 is typically 1.5-7.5 µg/mL." class="big_lightbox" target="_blank">
Laminins are essential and abundant structural non-collagenous glycoproteins localizing to basement membranes. Basement membranes (cellassociated extracellular matrices (ECMs)) are polymers of laminins with stabilizing type IV collagen networks, nidogen, and several proteoglycans.Basement membranes are found under epithelial layers, around the endothelium of blood vessels, and surrounding muscle, peripheral nerve, and fat cells. Formation of basement membranes influences cell proliferation, phenotype, migration, gene expression, and tissue architecture. Each laminin is a heterotrimer of alpha, beta, and gamma chain subunits that undergoes cell-secretion and incorporation into the ECM. Laminins can self-assemble, bind to other matrix macromolecules, and have unique and shared cell interactions mediated by integrins, dystroglycan, and cognate laminin receptors. The human laminin alpha-4 gene maps to chromosome 6q21 and is expressed in adult heart, lung, ovary, small and large intestines, liver, and placenta.
