Table 1 Distribution of 576 ESTs sequenced from S. c. edwardsii venom gland in toxin and toxin-like transcript, cellular protein, mitochondrial and hypothetical sequence clusters.

From: The venom gland transcriptome of the Desert Massasauga Rattlesnake (Sistrurus catenatus edwardsii): towards an understanding of venom composition among advanced snakes (Superfamily Colubroidea)
