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 I, 0.1 mg from Ace Therapeutics is purified from human placenta. 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.

Porcine Collagen Type I and III, 10 mg from Ace Therapeutics is purified from pig’s tissue. 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.

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.

Rat Collagen Type I and III, 10 mg from Ace Therapeutics is purified from rat tissue. 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.

Bovine Collagen Type V (Atelocollagen), 1 mg from Ace Therapeutics is purified from bovine placenta.

Human Collagen Type I from Ace Therapeutics is a purified collagen derived from adult human placenta tissue, and this product can be used as a thin layer on tissue culture surfaces to enhance cell adhesion and valorization.

Collagen Type VI is a multi-domain ECM. Its heterotrimeric chains pack into a microfibrillar network through tetramerization and tail-end linkage. Human Collagen Type VI from Ace Therapeutics is a purified collagen from adult placenta tissue. This product is usually used for coating and can also be added to cell culture fluid.

Rat Tail Tendon Collagen Type I from Ace Therapeutics is purified from rat tail by the Birkedal-Hansen method. This product can form a three-dimensional glue with a certain strength when the concentration is above 1mg/mL and the pH is around 7.

Human Collagen Type IV, 0.1mg from Ace Therapeutics is purified from human cartilage.
