The rat tail collagen I provided by Ace Therapeutics is prepared according to the Birkedal-Hansen method through acetic acid extraction, sodium chloride precipitation, and disodium hydrogen phosphate precipitation. This product is derived from a rat tail, dissolved in 0.02M HAc solution, and the purity is greater than 90% as determined by SDS-PAGE, and it is sterile.

Human Collagen Type III, 0.1 mg from Ace Therapeutics is purified from human cartilage. Type III collagen is the second most abundant collagen in tissues and is found most commonly in tissues exhibiting elastic properties such as skin, lungs, intestinal walls, and walls of blood vessels, which resembles other fibrillar collagens in structure and function. Type III collagen together with type I collagen are the main constituents of the interstitial matrix.

3-D Culture Matrix Collagen I from Ace Therapeutics is purified from rat tail tendon with high concentrations. This product is capable of polymerizing to form hydrogels and is a purified matrix ECM protein specifically designed and developed for 3D culture.

Collagens Type I-P is pepsin-solubilized Type-I collagen derived from pig skin. This product is suitable for coating.

Mouse Collagen Type I (Atelocollagen) from Ace Therapeutics is purified from the mouse tail tendon. Type I collagen is found in connective tissues and is the major component of tensile strength of the extracellular matrix (ECM). The product is widely used as a thin layer on tissue-culture surfaces to enhance the attachment and proliferation of a variety of cells including endothelial cells, fibroblasts, hepatocytes, epithelial cells, etc. In addition, the product can self-assemble into a 3-D supramolecular gel in vitro as an ideal biological scaffold.

Collagens Type I-P is pepsin-solubilized Type-I collagen derived from pig tendon. The product has low viscosity, making it easy to handle and form gels.

Soluble Collagen TypeⅠ from Ace Therapeutics is purified fromBovine achilles tendon by the Birkedal-Hansen method.

Collagen Type IV from Human Cell Culture from Ace Therapeutics is derived from human fibroblasts and epithelial cells in a co-culture system, which creates an in vitro ECM (extracellular matrix) and serves as an excellent biological scaffold for three-dimensional cell culture.

Mouse Collagen Type I and III, 5 mg from Ace Therapeutics is purified from rom tail tendons of the mouse. Type I collagen is the most abundant collagen and is found in connective tissues including tendons, ligaments, dermis, and blood vessels. Type III collagen is the second most abundant collagen in tissues and is found most commonly in tissues exhibiting elastic properties such as skin, lungs, intestinal walls, and walls of blood vessels, which resembles other fibrillar collagens in structure and function.

Collagens Type IV is derived from bovine tissue treated with pepsin. This product does not gel and needs to be mixed with collagen type I-A.
