The mouse 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 mouse tail, dissolved in 0.02M HAc solution, and the purity is greater than 90% as determined by SDS-PAGE, and it is sterile.

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 I from Ace Therapeutics is a purified stromal extracellular matrix protein from fetal bovine extensor tendons and is pepsin-treated to remove telopeptides. This product promotes cell adhesion for cell and tissue culture.

Rat Collagen Type I (Atelocollagen) from Ace Therapeutics is purified from the rat 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.

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.

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. Note: This product can quickly gel at RT when the pH is neutral. Keep the temperature as low as possible during the operation.

Rat Tail Collagen Type I, High Concentration, Sterile, Filtered, from Ace Therapeutics is a highly concentration, purified collagen derived from the rat tail. This product is more suitable for 3D cell culture due to the high concentration improves matrix stiffness and support integrity.

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.

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.
