Collagen type I (CI) protein, purified from rat tail tendon.



Type I collagen is the most abundant collagen and is found in connective tissues including tendon, ligament, dermis and blood vessel. It is the major component and the primary determinant of tensile strength of the extracelluar matrix (ECM). It 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, collagen I can self-assemble into a 3-D superamolecular gel in vitro, making it an ideal biological scaffold to promote more in vivo-like cellular morphology and function.

Rat collagen type I - 90%

Rat collagen type III - 10%

Other collagens - below 1%

Non-collagen proteins - below 0.5%


Form: 20 mg lyophilized, salt-free


Purification: Partial pepsin digestion in acidic conditions and differential salt precipitation.


Reconstitution: Use 0.5 M acetic acid, pH 2.5. Dissolved collagen retains immunologic properties of native collagen. Structure of native collagen confirmed by ability to form microfibrils.


Storage: Collagen dissolved in acetic acid is stable at 4 °C for 1 month. Lyophilized collagen long term storage (2 years) at -20°C or lower.
