Prepared from Human Skin Elastin, EPC No. GH421, by the method of Mecham and Lange (33). In the method, human skin elastin is extracted two times for 60 minutes at 37°C with 1 M NaOH in 80% ethanol. The second extraction supernatant is neutralized with HC103, clarified by centrifugation, dialyzed and lyophilized.
Human skin ETNA-elastin is a salt-free, water soluble powder.
Molecular Weight Range: 150 Kd to 60 Kd.
