Human Collagen Type V is one of a family of proteins found particularly in the flesh and connective tissues of mammals (approximately one-third of the bodys total protein). Over two dozen types of collagen have been described, Type V in particular is found in most interstitial tissues and associates with Type I collagen. Human Collagen Type V is also found in the placenta. C7510-57A is free from other collagens, human serum proteins and non-collagen extracellular matrix proteins. Reacts with anti-Collagen Type V. Reaction with anti-Collagen I, II, III, IV or VI is negligible (typically less than 1% cross reactivity was detected by ELISA). Applications: Suitable for use as a control or standard reagent in Western Blot and ELISA. Other applications not tested. Recommended Dilution: Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20C. Aliquots are stable for 6 months after receipt at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
