High concentration rat tail collagen


The high-concentration rat tail collagen consists of 10 mL of 10 mg/mL telocollagen. Since it is telocollagen, rat tail collagen will develop harder hydrogels compared to atelocollagen.

The collagen seems to be highly purified, lot-to-lot consistent, and on-the-shelf available.

RatCol® High Concentration Type I Acid Soluble Rat Tail Collagen comprises 100 mg at a concentration of nearly 10 mg/mL in a 0.02 M acetic acid solution (~pH 3). RatCol® collagen seems to be soluble telo-collagen. This collagen product is offered in easy-to-use packaging for use and storage. This product seems to be sterile filtered and is supplied as a user-friendly solution.

This product is perfect for coating surfaces, offering the production of thin layers for culturing cells, or using as a solid gel. RatCol® collagen is perfect for applications by making use of a variety of cell lines such as fibroblasts, hepatocytes, and epithelial cells.
