Comparative venomics of Naja naja from Indian and Sri Lanka have been carried out.
Differences in venom protein compositions representing intra-specific variations have been documented.
The neurotoxin/cytotoxin contents of the venoms explained well the clinical symptoms produced by these venoms.
Antivenomics study of an Indian antivenom showed lower binding affinity against the Sri Lankan cobra venom proteins.
The lower antibody binding affinity explained the poor efficacy of the Indian antivenom against Sri Lankan cobra envenoming.
