||Collagen type I & III-185
||Native Porcine Collagen type I & III was extracted from washed dissected tissue into dilute acetic acid after pepsin treatment.
||Porcine tissue. 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
||Porcine collagens: type I – 45%, type III – 45%, type IV – 10%, type V below 1%. Non-collagen proteins below 0.5%
||Coating material for cell culture studies. May not be suitable for 3-D gel formation
||Shipping at ambient temperature. Storage of lyophilized protein 2 years at -20 centigrade. Storage of reconstituted protein 1 month at +4 centigrade
||Use 0.5 M acetic acid, pH 3.0. Dissolved collagen retains immunologic properties of native collagen. Structure of native collagen confirmed by ability to form microfibrils
