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 ...

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 ...

A comparative study of the homology of certain enzymes in elapid venoms
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1971Abstract 1. 1. Similar electrophoretic mobilities for esterases with identical substrate specificities have been shown for the venoms of several closely related elapidae. 2. 2. Two lactate dehydrogenase isozymes were shown for most Naja venoms with the slower migrating band (at alkaline pH's) showing constant mobility for all Naja species

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 ...

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

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 ...

Immunological and histochemical identity of esterases and other antigens in elapid venoms
Toxicon, 1972Abstract Antibodies were prepared by hyperimmunizing rabbits with Naja naja, Bungarus fasciatus, Agkistrodon piscivorus and Apis mellifera (honeybee) venoms. By using immuno-electrophoresis, Ouchterlony technique and histochemical reactions, the identity of certain antigenic components and esterases in several elapid venoms has been demonstrated.

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.
