The canine aortic elastin is purified by the method of Starcher et al. (3) in which contaminating proteins are removed by mild extraction conditions. This method minimizes peptide bond cleavage. Thhis elastin is insoluble.
The purity of the elastin is based upon the percent insoluble residue that remains after digestion with porcine elastase. Canine Aortic Elastin, EPC No. SC55 contains less than 0.08% insoluble residue after elastolysis.
