Abstract: The present invention relates to the technical sector of the polymerisation of acrylic acid and its salts, more particularly in solution, more particularly by controlled radical method, the use of the corresponding organo-sulphurated transfer agents, the acrylic acid polymers thus obtained, having a very low polydispersity PD (or very low polymolecularity index IP, which is an equivalent term), and their applications in industry.

Abstract: 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 recognizing 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.
