Collagen IV alpha 1 Antibody (577238) [Unconjugated]

Collagen IV a1 was detected in immersion fixed T98G human glioblastoma cell line using Mouse Anti-Human Collagen IV alpha 1 Monoclonal Antibody (Catalog # MAB6308) 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 perinuclear areas and cytoplasm. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Background

COL4A1 (collagen IV alpha 1) is a 185 kDa member of the type IV collagen family.  It is a secreted glycoprotein that is expressed by multiple cell types, including fibroblasts, keratinocytes and endothelial cells.  Two COL4A1 molecules interact with a 170 kDa alpha 2 chain to form a collagen IV triple helix.  This helix further interacts with other helices to generate covalent oligomers that form a scaffold in the basement membrane.  Mature human COL4A1 is 1642 amino acids (aa) in length.  It has an N-terminal “7S” proregion (aa 28-172), a central collagenous domain that contains multiple Gly-based repeats (aa 173-1440), and a C-terminal domain that is proteolytically cleaved to generate a 25-28 kDa NC1 globular segment that has potent antiangiogenic activity (aa 1441-1669).  Multiple splice forms exist.  One shows a deletion of aa 499-849, a second shows a seven aa substitution for aa 513-1669, and a third shows a seven aa substitution for aa 958-1669.  Over aa 1441-1669, human COL4A1 is 97% aa identical to mouse COL4A1.
