Bovine collagen type I and III protein purified from calf skin


Bovine (calf) skin. Collagen was extracted from washed dissected tissue into dilute acetic acid after pepsin treatment. Collagen type I and III was purified by using differential salt precipitation


Bovine collagen type I 45%, bovine collagen type III 45%, bovine collagen other types <10%, non-collagen proteins <0.5%


Lyophilized, salt-free


Partial pepsin digestion in acidic conditions and differential salt precipitation


Coating material for cell culture studies. May not be suitable for 3-D gel formation


Use 0.5 M acetic acid, pH 2.5. Dissolved collagen retains immunologic properties of native collagen. Structure of native collagen confirmed by ability to form microfibrils


Shipping at ambient temperature. Storage of lyophilized protein 2 years at -20°C. Storage of reconstituted protein 1 month at +4°C. Do not freeze reconstituted collagen
