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 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.

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.

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.

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.

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.

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

Porcine Gelatine from Ace Therapeutics is a purified gelatin matrix from porcine tissue. The product can enhance the adsorption of various normal cells and transfected cells.

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.

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