title: Determination of soluble antigens of Clostridium botulinum A by chemiluminescent--immunosorbent assay (CLISA).
abstract: The chemiluminescent--immunosorbent assay (CLISA) was adopted for Cl. botulinum A soluble toxic antigens determination. Luminol (ABEI) labelled botulinum antitoxin globulins showed a strongly positive specific immunochemiluminescent reactions with the native botulinum toxin preparations coupled (adsorbed) on polystyrene balls. The sensitivity of the reaction reached 20 DLM/ml (5,000 light impulses per 40 sec) in comparison with 2 X 10(6) DLM (57,000 impulses), control preparations (1,500 impulses) and the background (150-300 impulses). The results give a perspective further investigations with the CLISA for rapid indication of Cl. botulinum toxic antigens.
