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.

Rat Collagen I, Low Viscosity from Ace Therapeutics is a purified stromal extracellular matrix protein from rat tail tendons. This product is provided at a standard concentration that is lower in viscosity, making it easier to work with.

Goat Collagen Type I, 10 mg from Ace Therapeutics is purified from goat tissue. 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 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 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.

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

Bovine Collagen Type III, 10 mg from Ace Therapeutics is purified from bovine (calf ) skin. 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.

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.

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.

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.
