title: A simple haemolytic method for quantitation of the delta endotoxin of Bacillus thuringiensis subsp. israelensis from crude samples.
abstract: A simple haemolytic assay method for quantitative estimation of the delta endotoxin of Bacillus thuringiensis subsp. israelensis from a crude preparation has been developed. The method has several advantages over mosquito-larvicidal methods of assay as it is inexpensive, highly sensitive and easier to run and can be used for performing a reasonably large number of assays rapidly with high precision and with a coefficient of variation that does not exceed 1.96%.
