Porcine collagen type I and III purified from porcine tendons


Source

Porcine tendons. 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


Purity

Porcine collagens: type I and III 95%, other collagen types below 1%. Non-collagen proteins below 0.5%


Format

Lyophilized, salt-free


Purification

Partial pepsin digestion in acidic conditions and differential salt precipitation


Applications

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

Pig cell migration assay (1)


Reconstitution

Use acetic acid, pH 2.5 in concentration from 0.02 to 0.5M. Dissolved collagen retains immunologic properties of native collagen. Structure of native collagen confirmed by ability to form microfibrils


Storage

Shipping at ambient temperature. Storage of lyophilized protein at -20°C. Storage of reconstituted protein 1 month at +4°C
