摘要:
The invention relates to a device for presenting peptides or proteins which can be used as a polypeptide chip for miniaturized detection of molecules which structurally or functionally complement said polypeptides. Said device consists of a flat support where polypeptides are covalently bound. The link between the polypeptides and the support results from the formation of a semicarbazone link. The semicarbazone link is a specific result of the reaction between polypeptides having an aldehyde or ketone function; and a support functionalized by semicarbazide groupings. The invention also relates to a method for preparing the supports and attaching the polypeptides to these supports in addition to the use of said devices thus obtained as polypeptide chips .
