Componenti
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.
Avvertenza
This product should be stored desiccated at -20°C, and will retain activity in these conditions for 3 years.
Nota sulla preparazione
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.
Risultati analitici
An SDS polyacrylamide gel electrophoresis test run under reducing conditions consistent with basement membrane collagen yields three major bands.
Altre note
Il collagene è classificato in diversi tipi strutturalmente e geneticamente distinti. Sigma utilizza la nomenclatura proposta da Bornstein e Traub. Occorre prestare attenzione a non confondere le denominazioni delle tipologie Sigma con le classificazioni del collagene universalmente riconosciute.
