gurukan and/or substrate for endotokishin measurement and measuring method

摘要

This invention peptide derivative for -gurukan or endotokishin measurement which makes high sensitometry possible and -gurukan which uses that and/or to designate the offer of endotokishin measuring method as topic, (1) the below-mentioned general formula [1]X-A₁ - Gly-Arg-A₂ - E - D [1]So the peptide derivative which is shown, (2) the above-mentioned peptide derivative is contained, the below-mentioned general formula which gurukan and/or the reagent for endotokishin measurement, (3) gurukan and/or reacts with the sample and the horseshoe crab blood corpuscle component and the above-mentioned peptide derivative which include endotokishin, as a result separates [2]H-A₂ - E - D [2]The unreacted substance and it separates measures, gurukan which becomes the horseshoe crab blood corpuscle component and the above-mentioned peptide derivative, gurukan which features that it does on the basis of the value and/or measuring method of endotokishin, (4) as the constitution component including and/or it regards the reagent kit for measurement of entodokishin.
