Components
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
This product should be stored desiccated at -20°C, and will retain activity in these conditions for 3 years.
Preparation Note
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
An SDS polyacrylamide gel electrophoresis test run under reducing conditions consistent with basement membrane collagen yields three major bands.
Other Notes
El colágeno se clasifica en una serie de distintos tipos desde el punto de vista estructural y genético. Nosotros utilizamos la nomenclatura propuesta por Bornstein y Traub. Tenga cuidado de no confundir las designaciones de tipo Sigma con los tipos de clasificación de colágeno reconocidos
