Collagen Core

The Center of Excellence for Diseases of Connective Tissues maintains a core facility for the large-scale purification of collagen, and the production of alpha chains and CB peptides for research in autoimmunity. Tissues used as a source of cartilage are obtained exclusively from meat packing industry by-products.

Presently, these collagens are available from our core service at prices competitive with commercial entities providing this grade of product.

If you are interested in further information regarding pricing and availability
of collagen from our core service, please contact David Brand.
