Abstract (en)

[origin: FR2762394A1] The invention concerns a method for isolating a target biological material contained in a sample, consisting in the following steps: providing a capture phase, in microparticulate or linear form, consisting of at least a first particulate or linear polymer, with apparent hydrophile character and first complexing groups, the latter being bound by co-ordination to a first transition metal, which is itself bound to a first biological entity capable of specifically recognising the target biological material; contacting said target biological material with at least the capture phase; and detecting the capture phase-target biological material complex, optionally with a detection phase, in microparticulate or linear form, and consisting of at least a second particulate or linear polymer, with apparent hydrophile character and second complexing groups, the latter being bound by co-ordination to a second transition metal, which is itself bound to a second biological entity capable of specifically recognising the target biological material, and a marker.
