The optimum conditions for the selective removal of elastin from connective tissues are described. The process, elastolysis, consists of incubating small samples of connective tissue in buffered saline at ph=8.6 containing 300 microgram/me of a 50-50% mixture of elastase with trypsin inhibitor, for 5-6 hours at room temperature. This process, complimented with other processes for selective removal of lipids, or mucopolysaccharides, or collagen, enables one to examine the contribution of the various components of the connective tissue to its mechanical function. The elastolysis was tested with aortic, valvular and tendon tissues from human, bovine and canine species and it was found that in tensile stress experiments, collagen was unaffected while the low-stress contribution of elastin disappeared.
