Componentes

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.

Atenção

This product should be stored desiccated at -20°C, and will retain activity in these conditions for 3 years.

Nota de preparo

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.

Nota de análise

An SDS polyacrylamide gel electrophoresis test run under reducing conditions consistent with basement membrane collagen yields three major bands.

Outras notas

O colágeno é classificado em diversos tipos estrutural e geneticamente distintos. Usamos a nomenclatura proposta por Bornstein e Traub. Tome cuidado para não confundir as designações de tipos da Sigma com tipos de classificação de colágenos reconhecidos.
