METHOD FOR ISOLATING A TARGET BIOLOGICAL MATERIAL, CAPTURE PHASE, DETECTING PHASE AND REAGENT CONTAINING THEM

摘要

The invention concerns a method for isolating a target biological material contained in a sample, which consists in providing a capture phase comprising an organic molecule having at least a reactive function and at least a protein material capable of recognising or binding, specifically and directly or indirectly, with the target biological material, said protein material having a specific covalent binding site with the organic molecule reactive function, consisting of at least a tag comprising at least six contiguous lysine, or lysine derivative residues; the method consists in contacting said target biological material with at least the capture phase; and detecting the target biological material fixed on the capture phase: The invention also concerns the capture and detection phases, and a reagent containing them.
