详细信息:Collagen type IV is the major structural element of basal membranes. Human collagen type IV is a native triple helix. Collagen was extracted from washed dissected tissue into dilute acetic acid after mild pepsin treatment. The Collagen type IV was purified by using differential salt precipitation. Purity and retention of native helical structure was controlled by SDS-PAGE and by reaction with anti-collagen type specific monoclonal antibodies. Molecular weight: 300kDa;Human Collagen Type IV
