商品描述
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.
PureCol-S 胶原蛋白作为一种标准品在试验中使用是必要的成分。PureCol-S胶原蛋白的标准是约97%的I型胶原蛋白,其余的为III型胶原蛋白,它具有很高的单体含量可以用于测试凝胶渗透色谱。本片的浓度约为3 mg/ml,浓度为双缩脲蛋白测定法验证。每个批次的具体浓度会写于产品的COA上随货发出。PureCol-S是溶于0.01N盐酸的端胶原蛋白,因此它的PH值约为2。PureCol®-S是一种理想的,使用在控制测试和检验程序的胶原蛋白标准品,它是无菌过滤的,可随时使用。
