General description

Anti-Collagen Type IV antibody, Mouse monoclonal (mouse IgG1 isotype) is derived from the col-94 hybridoma, produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mouse immunized with human collagen Type IV. Collagen Type IV (also known as COL4A) is a key component of the basement membranes (BM), which is found at the basal surface of epithelial and endothelial cells and is essential for tissue strength and polarity. Type IV Collagens are encoded by three pairs of paralogous genes (COL4A1 through COL4A6).

Immunogen

human collagen Type IV

Application

Anti-Collagen Type IV antibody, Mouse monoclonal has been used in immunohistochemistry and dot-blotting.

Biochem/physiol Actions

Collagen Type IV represents a physical barrier against cell invasion. Proteolysis/degradation of Collagen Type IV is essential for cell migration and cancer cells invasion through the ECM into the interstitial tissues.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Heterotrimers composed of collagen type IV alpha 1 (COL4A1) and alpha 2 (COL4A2) constitute one of the most abundant components of nearly all basement membranes. Accordingly, mutations in COL4A1 or COL4A2 are pleiotropic and contribute to a broad spectrum of

In this study, we extracted prostate cell-specific gene sets (metagenes) to define the epithelial differentiation status of prostate cancers and, using a deconvolution-based strategy, interrogated thousands of primary and metastatic tumors in public gene profiling datasets. We identified a subgroup
