Rat Tail Tendon Collagen Type I, 5mg/ml is prepared by the method of Birkedal-Hansen through acetic acid extraction, sodium chloride precipitation, disodium hydrogen phosphate precipitation, and other steps. This product can be used to coat cell culture vessels and culture some cells that are difficult to adhere to in ordinary cell culture vessels. It can also be used to prepare three-dimensional glue to simulate a real growth environment and allow cells to grow in a three-dimensional environment.

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.

Human Collagen Type IV from Human Cell Culture from Ace Therapeutics is derived from human placenta.

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.

Collagen Type V is found in the placenta, amniotic membrane, and cornea. Human Collagen Type V from Ace Therapeutics is a purified collagen from adult human placenta tissue. This product can be used as a coating on tissue culture surfaces to study the effects of collagen on cell behavior.

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.

Mouse Collagen Type I, 1 mg from Ace Therapeutics is purified from 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.

Collagen Type IV is a common component of the basement membrane. Mouse Collagen Type IV from Ace Therapeutics is a purified collagen derived from murine engelbreth-holm-swarm (EHS) tumor, and the product can be used to regulate cell growth, differentiation, and tissue formation.

Collagens Type I-A is acid-soluble Type-I collagen derived from porcine tendon. This product can quickly form a gel and is suitable for 3D cell culture products. It has high gel strength and transparency and is easy to observe under the microscope.

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.
