Storage

Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/mL BSA, 50% glycerol, and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibody.

Specificity / Sensitivity

COL2A1 (E8S2S) Rabbit mAb recognizes endogenous levels of total COL2A1 protein. This antibody detects a non-specific 62 kDa band with unknown origin.

Human

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ala194 of human COL2A1 protein.

Background

COL2A1 (α1 type II collagen) is a fibril-forming collagen encoded by the gene COL2A1 (1,2). The protein forms homotrimeric type II collagen and is the main extracellular component in hyaline cartilage extracellular matrix (ECM), nucleus pulposus of intervertebral discus, vitreous humor of the eye, and inner ear structure (3). Type II collagen plays a fundamental role in maintaining cartilage formation, differentiation, and growth (4-6). Mutations of COL2A1 cause impairment of ECM deposition and signaling, which contribute to various forms of tissue dysplasia and pathologies such as Stickler syndrome and chondrosarcoma (3,7,8). At the ECM, COL2A1 interacts with integrins such as integrin β1 and growth factors such as IL1β, IL6, IL8, and others, which activate intracellular signaling pathways, including SMAD1, and MAP kinases p38, JNK, and ERK (9-12).

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.
