Collagen Type III is found in a variety of conjunctival tissues, including human skin, and the cornea. Human Collagen Type III from Ace Therapeutics is a purified collagen derived from adult human placenta tissue, and the product can be used as a coating on tissue culture surfaces to promote cell adhesion and regulate cell behavior.

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.

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 a sterile solution dissolved in 6mM HAc, with a concentration of 5mg/ml. Each batch of products passes cell culture testing (including three-dimensional space culture) to ensure quality reliability. Note: Please keep the entire operation at a low temperature on ice because rat tail collagen I at room temperature can quickly form a gel.

Bovine Collagen Type I from Ace Therapeutics is a purified collagen derived from bovine tissue. The native collagen sequence contained in the preparation is missing or shortened since this product has been treated with pepsin.

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.

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.

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.

Rat Tail Collagen I, 3 mg/mL from Ace Therapeutics is derived from rat tail, which can be prepared as a clear gel to provide a 3D matrix or surface coating on tissue culture plates as a substrate for culturing primary cells such as keratinocytes and hepatocytes.

Collagen from Human Placenta is used to induce differentiation of endothelial cells and rat pluripotent cells. This product is a lyophilized powder that can be reconstituted at 1 mg/mL in sterile 0.5 M acetic acid, PBS, or water.

Bovine Collagen Type I and III, 10 mg from Ace Therapeutics is purified from calf skin. 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.
