>>Has anyone done research on Heteradon Nasicus?

Hi mate

We did have a look at Heterodon nasicus venom. Go to the publication section of my webpage and the papers are in there (specifically the alpha-colubritoxin and Colubroidea LC/MS papers). I've put the link to the Colubroidea LC/MS paper below.

Cheers
