An enzyme immunoassay for isotyping mouse monoclonal antibodies.

A rapid, simply performed and relatively inexpensive enzyme immunoassay for isotyping mouse monoclonal antibodies is described, based on the urease/urea system. Because of the high sensitivity (less than 0.1 microgram/ml of immunoglobulin can be detected in cell culture medium) no treatment of the hybridoma supernatant sample is required prior to assay, and the isotype of a mouse immunoglobulin can be determined in about thirty minutes.

Rationalisation of first-aid measures for elapid snakebite.

The plasma of monkeys envenomated with tiger snake (Notechis scutatus) venom was monitored by radioimmunoassay for both crude venom and a neurotoxin. When the injected limb was immobilised and a pressure of 55 mm Hg applied to the injection site, only very low levels of circulating venom or neurotoxin were detectable. In practical terms, venom movement can be effectively delayed for long periods by the application of a firm crepe bandage to the length of the bitten limb combined with immobilisation by a splint. Pressure alone or immobilisation alone did not delay venom movement.

Three instructive cases of tiger snake (Notechis scutatus) envenomation--and how a radioimmunoassay proved the diagnosis.

Three unusual cases are described, in which, in separate incidents, young snake bite victims were found comatose. Tiger snake vemon was detected by radioimmunoassay in the urine and serum, and in one case on the clothing of these children. Gross myoglobinuria was present in all cases. The three cases demonstrate clearly the myolytic potential of tiger snake venom if specific treatment (administration of antivenom) is delayed. Extreme elevation of serum enzyme levels was found in the two victims who survived. Evidence was obtained that the major neurotoxin of tiger snake venom is absorbed at least partly via the lymphatics and that some is excreted in the urine.
