Abstract: A blasting cartridge comprising an elongated sleeve extending along an axis A and having a first end and a second end; the first end has a first sleeve closure with an opening for holding a detonator; the second end has a second sleeve closure; a space is provided between the first sleeve closure and the second sleeve closure for holding a blasting explosive; wherein the second end is provided with a connector means for releasably connecting the second end of the cartridge with a first end of an adjacent cartridge and comprising a firing pin means for impinging upon a detonator in the first end of the adjacent cartridge when the blasting explosive is detonated by actuation of the detonator in the first end of the cartridge.

Abstract: A method for detecting the presence or concentration of an analyte in a sample, wherein: a) the sample is contacted with an immobilized first binding reagent which is capable of binding the analyte if present in the sample; b) the sample is contacted with a second binding reagent which comprises a fusion protein having a reporter domain and a binding domain, and which is capable of binding the analyte if present in the sample, the first and second binding reagents being capable of binding the analyte simultaneously if present in the sample, such that said second binding reagent becomes immobilized through the analyte bound to the first binding reagent; and detecting whether the second binding reagent has become immobilized to thereby detect the presence or concentration of said analyte.
