Product Description PureCol ® -S collagen is provided as a standard for use in assays where ultra-pure collagen is required. PureCol ® -S collagen standard is approximately 97% Type I collagen with the remainder being comprised of Type III collagen. It contains a high monomer content as measured by gel permeation chromatography. This product is supplied at approximately a 3 mg/ml concentration. The concentration is confirmed by Biuret protein determination assay. The concentration for each specific lot is provided on a Certificate of Analysis that is available with the purchase of each product. PureCol®-S is soluble atelo-collagen in 0.01 N HCI, therefore, the pH is approximately 2.0. PureCol ® -S is ideal for using as a collagen standard in controlled testing and assay procedures. PureCol ® -S is sterile filtered and is supplied as a ready to use solution.
