Conformational Properties of the Neurotoxins and Cytotoxins Isolated from Elapid Snake Venoms
Critical Reviews in Biochemistry, 1983The review will critically assess the information available on the conformation of homologous neurotoxins and cytotoxins isolated from Elapid snakes. Particular attention will be given to the dynamics of the molecules in solution because there is the possibility that defined intramolecular rearrangements are involved at the sites of action.

Preliminary studies on small molecular toxic components of elapid venoms
Toxicon, 1969Abstract Venoms of certain elapid snakes ( Naja , Hemachatus , Ophiophagus , Bungarus , Dendroaspis and Pseudechis ) were dialyzed against distilled water for 48 hr. The dialysates were compared by chromatography and electrophoresis. Unlike viperid and crotalid venoms ( Vipera , Bitis , Crotalus and Bothrops ), elapid venoms are highly ...

Non-conventional toxins from Elapid venoms
Toxicon, 2003Non-conventional toxins constitute a poorly characterized class of three-finger toxins isolated exclusively from Elapidae venoms. These toxins are monomers of 62-68 amino acid residues and contain five disulfide bridges. However, unlike alpha/kappa-neurotoxins and kappa-neurotoxins which have the fifth disulfide bridge in their middle loop (loop II ...

Comparative studies on Egyptian elapid venoms
Zeitschrift für Ernährungswissenschaft, 1980The immunological properties of Naja haje from Western Desert, Naja haje of the Nile Delta, Naja nigricollis from Upper Egypt and Walternnesia aegyptia from Sinai Desert were compared using horse serum antivenin prepared from the Delta Naja haje venom. All elapid venoms showed very similar precipitin lines with immunodiffusion or immunoelectrophoresis ...

Species differences in susceptibility to elapid venoms
Toxicon, 1969Birds (pigeon, chick and Formosan sharp-tailed munia) are extremely susceptible to the lethal action of the venom of Bungarus multicinctus as compared with mammals. Comparison of the neuromuscular blocking activity of α- and β-bungarotoxin in chick's biventer cervicis muscle reveals that avian muscle is particularly susceptible to β- but not to α ...

Properties of some 3-nitrotyrosyl elapid venom cardiotoxins
International Journal of Biochemistry, 1987Nitration of the invariant Tyr-22 in Hemachatus haemachates cardiotoxin 12B did not greatly decrease lethality, and the haemolytic potency towards guinea-pig erythrocytes remained unchanged. This residue is thus non-essential for cardiotoxin to exert its biological action.

Identification and discrimination of snake venoms from Egyptian elapids
Toxicon, 2013The avidity to the corresponding antigens is often higher than to the cross-reactive antigens. This was demonstrated with the highly cross-reactive elapid Egyptian snake venoms Naja haje (Nh), Naja nigricollis (Nn) and Walterinnesia aegyptia (Wa), and used for the differentiation among the three species in a simple ELISA-based assay.

Further studies on the mass of venom injected by Elapid snakes
Toxicon, 1983Further experimental studies to determine the mass of venom injected by medically-significant Australian elapids are reported. The use of a modified enzyme immunoassay technique to measure venom injected during snake bite is presented. The feeding biting pattern of the Australian eastern brown snake (Pseudonaja textilis) is described.

Proteins toxic to arthropods in the venom of elapid snakes
Journal of Insect Physiology, 1975It has been found that the lethal action of elapid snake venoms to arthropods (fly larvae and isopods) is due to proteic factors differing from the toxins which are strongly and specifically active on mammals. This conclusion was based on the following: (1) Lack of any correlation between the toxic activity on larvae, isopods, and mice of ten elapid

A comparative study of the biological properties of Australian elapid venoms
Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 19901. The hemorrhagic, procoagulant, anticoagulant, protease, phosphodiesterase, alkaline phosphomonoesterase, L-amino acid oxidase, acetylcholinesterase, arginine ester hydrolase, phospholipase A, 5'-nucleotidase and hyaluronidase activities of 39 samples of venoms from 13 species (15 taxa) of Australian elapids were determined and the Sephadex G-75 gel ...
