Abstract

The venoms from two species of rock rattlesnakes and an intergrade population were studied. Differences were noted in SDS-PAGE and RP-HPLC profiles and only the venom from the intergrade population showed low procoagulant activity. Also, a Crotoxin-like neurotoxic PLA2 was identified in the venom of C. l. klauberi, the most toxic of the analyzed venoms. This is the first report of such a toxin in C. l. klauberi from Aguascalientes, Mexico.
