Abstract:
1. A low-molecular-weight water-soluble elastin having a molecular weight of about 10,000 to 30,000 daltons, purified from a dissolved-elastin solubilizing liquid obtained by dissolving an insoluble elastin obtained from animal body tissue in an aqueous solution of one or more alkali compounds selected from the group consisting of sodium hydroxide, potassium hydroxide, calcium hydroxide, and barium hydroxide, 79% to 84% of the constituent amino acids of the elastin comprising proline, glycine, alanine, and valine, 2% to 3% comprising aspartic acid and glutamic acid, 0.7% to 1.3% comprising lysine, histidine, and arginine, and 0.2% to 0.4% comprising desmosine and isodesmosine.
