The Naja Kaouthia venom is a member of the snake three-finger toxin family in the subfamily type II alpha-neurotoxin. The lethal dose (LD50) of α-cobratoxin is 0,1 mg/kg by intravenous injection into mice15. The toxin occurs as a monomer but can form a homodimer or heterodimers with cytotoxins 1,2, and 3 through disulfide linkage.
Mortality rate for Naja atra is between 15 and 20%, 5–10% for N. nigricollis, [33] 50% for N. nivea, [30] 20–25% for N. naja, [34] In cases where victims of cobra bites are medically treated using normal treatment protocol for elapid type envenomation, differences in prognosis depend on the cobra species involved. The vast majority of ...

Cardiotoxin III (CTX III, also known as cytotoxin 3) is a sixty amino-acid polypeptide toxin from the Taiwan cobra Naja atra. CTX III is highly basic and hydrophobic protein. [1] It is an example of a group of snake cardio/cytotoxins (InterPro: IPR003572), which are made up of shorter snake venom three-finger toxins. Over 50 different cytotoxin ...
