Collagen alpha-2(VI) chain

For Research Use Only. Not for use in diagnostic procedures.

Polyclonal

Rabbit

Recognizes endogenous levels of Collagen 6 alpha 2 protein.

The antibody was purified by immunogen affinity chromatography.

Liquid in 0.42% Potassium phosphate, 0.87% Sodium chloride, pH 7.3, 30% glycerol, and 0.01% sodium azide.

Shipped at 4 degree C. Upon delivery aliquot and store at -20 degree C for one year. Avoid freeze/thaw cycles.

Small volumes of anti-COL6A2 antibody vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

Rabbit polyclonal antibody to Collagen 6 alpha 2

Western Blot (WB), Immunohistochemistry (IHC), Immunofluorescence (IF), Immunocytochemistry (ICC), Immunoprecipitation (IP)

WB (1/500 - 1/1000), IH (1/100 - 1/200), IF/ICC (1/100 - 1/500), IP (1/10 - 1/100)

Western blot analysis of Collagen 6 alpha 2 expression in HepG2 (A), HT29 (B) whole cell lysates.

Immunohistochemical analysis of Collagen 6 alpha 2 staining in human lung cancer formalin fixed paraffin embedded tissue section. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0). The section was then incubated with the antibody at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

Immunofluorescent analysis of Collagen 6 alpha 2 staining in HT29 cells. Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with the primary antibody in 3% BSA-PBS and incubated overnight at 4 °C in a humidified chamber. Cells were washed with PBST and incubated with a DyLight 594-conjugated secondary antibody (red) in PBS at room temperature in the dark. DAPI was used to stain the cell nuclei (blue).

Collagen alpha-2(VI) chain

CO6A2_HUMAN

This gene encodes one of the three alpha chains of type VI collagen, a beaded filament collagen found in most connective tissues. The product of this gene contains several domains similar to von Willebrand Factor type A domains. These domains have been shown to bind extracellular matrix proteins, an interaction that explains the importance of this collagen in organizing matrix components. Mutations in this gene are associated with Bethlem myopathy and Ullrich scleroatonic muscular dystrophy. Three transcript variants have been identified for this gene. [provided by RefSeq, Jul 2008]

COL6A2: Collagen VI acts as a cell-binding protein. Defects in COL6A2 are a cause of Bethlem myopathy (BM). BM is a rare autosomal dominant proximal myopathy characterized by early childhood onset (complete penetrance by the age of 5) and joint contractures most frequently affecting the elbows and ankles. Defects in COL6A2 are a cause of Ullrich congenital muscular dystrophy (UCMD); also known as Ullrich scleroatonic muscular dystrophy. UCMD is an autosomal recessive congenital myopathy characterized by muscle weakness and multiple joint contractures, generally noted at birth or early infancy. The clinical course is more severe than in Bethlem myopathy. Defects in COL6A2 are the cause of myosclerosis autosomal recessive (MYOSAR); also known as myosclerotic myopathy or congenital myosclerosis of Lowenthal. A condition characterized by chronic inflammation of skeletal muscle with hyperplasia of the interstitial connective tissue. The clinical picture includes slender muscles with firm 'woody' consistency and restriction of movement of many joints because of muscle contractures. Belongs to the type VI collagen family. 3 isoforms of the human protein are produced by alternative splicing.
