Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human COL3A1 protein.
Background
The Extracellular Matrix (ECM) is a complex network of macromolecules that provides structural tissue support to cells in the basement membrane and interstitial matrix. It is composed of many molecules including proteins, glycoproteins, proteoglycans, and polysaccharides (1,2). One of the major proteins that comprises the ECM, and the human body, is collagen. Collagens are a large family of proteins. They are trimeric molecules comprised of three alpha polypeptide chains that form a triple helix structure that is characteristic of all collagens (3). The large family of collagens is divided into three subgroups: fibrillar collagens, non-fibril forming collagens, and fibril-associated collagens. These subgroups differ in their structure and supramolecular assembly (3).
COL3A1 (Collagen 3 alpha 1) is a major fibrillar collagen comprised of three identical alpha-1 chains. It is present in most soft tissues along with COL1A1, and is particularly high in tissues exhibiting elastic properties, such as the cardiac arterial wall and skin (4). Heterozygous mutations in the COL3A1 gene that cause missense mutation of a critical glycine residue in the triple helical domain of the alpha-1 chain result in vascular Ehlers-Danlos syndrome (vEDS). This mutation interferes with the ability of the alpha-1 chain to form collagen fibrils and thus disrupts macromolecular assembly of collagen fibers. vEDS is a severe and life-threatening disease as patients have a propensity for rupture of large arteries (4).
Increased amounts of type III COL3A1 are found in many fibrotic conditions, such as lung, liver, kidney fibrosis, and systemic sclerosis (5,6).

Species Reactivity
Species reactivity is determined by testing in at least one approved application (e.g., western blot).
Western Blot Buffer
IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
