Contaminants: <2% collagen type I, <1% collagen type III, <2% collagen type IV and <0.5% non-collagen proteins.
Molecular composition: (a1(V))2 a2(V), native triple helix. Purity and retention of native helical structure was monitored by SDS-PAGE, ORD measurement, and by reaction with anti-collagen type-specific monoclonal antibodies.
Storage and Stability:May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 6 months after receipt at -20°C. 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.
