Immunological detection method

摘要

The present invention relates to an antibody which reacts specifically with the binding proteins for Bacillus thuringiensis delta endotoxins and the derivatives thereof. It furthermore relates to an anti-idiotype antibody which reacts specifically with the binding proteins for B. thuringiensis delta endotoxins and the derivatives thereof. The present invention further relates to an assay kit which contains an antibody according to the invention. The invention additionally relates to a method for isolating a B. thuringiensis delta endotoxin; to the resulting B. thuringiensis delta endotoxin; to a method for the identification of a B. thuringiensis delta endotoxin which recognises a binding protein; to the resulting B. thuringiensis delta endotoxin; to a method for determining the amount of binding protein present and to a method for reducing the potential for development of resistance in the control of pests. The present invention further relates to the use of antibodies and assay kits according to the invention in the analysis of the immunological cross-reactivity of toxin binding proteins to determine their degree of relationship and to determine the availability and accessibility of a binding protein for the appropriate toxin in various insects. The present invention furthermore embraces the use of the antibodies according to the invention for the analysis of resistances which are attributable to the absence of the binding protein or of the binding sites.
