Molecular composition: [a1(III)]3 , native triple helix. Dissolved collagen retains the ability to form microfibrils, activate platelet aggregation and serve as a substrate for cell growth in culture
Collagen was extracted from washed, dissected tissue into dilute acetic acid after mild pepsin treatment. Collagen type III was purified using differential salt precipitation.
Contaminants: Contains >10% bovine collagen type I and >0.5% non-collagen proteins
Storage and Stability:
Lyophilized powder may be stored at 4 degrees C for short-term only. Reconstitute to nominal volume by adding 0.5M acetic acid and store at -20 degrees C. Stable for 12 months at -20 degrees C.
