基本信息
| EC number【EC 号】 | 232-697-4 |
| MDL number | MFCD00130825 |
| NACRES | NA.32 |
| Components【组分】 | All collagen molecules are composed of three polypeptide chains arranged in a triple helical conformation, with a primary structure that is mostly a repeating motif with glycine in every third position and proline or 4-hydroxyproline frequently preceding the glycine residue. |
| Caution【注意】 | This product should be stored desiccated at -20℃, and will retain activity in these conditions for 3 years. |
| Preparation Note【制备说明】 | This product was prepared by a modification of the pepsin extraction and salt fractionation method of Niyibizi, C., et al., J. Biol. Chem., 259, 14170 (1984). It is an acid soluble collagen that can be dissolved in water with acetic acid added to pH 3.0 (5 mg/mL), yielding an opalescent, colorless solution. |
| Analysis Note【分析说明】 | An SDS polyacrylamide gel electrophoresis test run under reducing conditions consistent with basement membrane collagen yields three major bands. |
| Other Notes【其他说明】 | 胶原蛋白被分为许多种结构和遗传性不同的类型。 我们使用 Bornstein和Traub提出的系统命名法。 小心不要混淆Sigma命名系统和通用的胶原蛋白分类类型。 |
