Abstract

Two phospholipases A2 of mol. wt 14,500 (P1) and 14,400 (P2) and pI 9.2 and 7.4 respectively were isolated from Crotalus scutulatus scutulatus venom. The two isoenzymes cross-reacted immunologically with phospholipase A2 from C. adamanteus and C, atrox, but not with Mojave toxin, excluding them as the basic subunit of the Mojave toxin complex. C. s. scutulatus venoms from Arizona had two common bands recognized by anti-P2 which were absent in most C. s. scutulatus venoms from Texas, suggesting two genetically different populations east and west of the Continental Divide.
