Method for the identification and/or the quantification of a target compound obtained from a biological sample upon chips
First Claim
1. A method for an identification and/or the quantification of a target compound obtained from a sample, preferably a biological sample, comprising the steps of:
- (a) putting into contact the target compound with a capture molecule in order to allow a specific binding between said target compound with a capture molecule, said capture molecule being fixed upon a surface of a solid support according to an array comprising a density of at least 20 discrete regions per cm2, each of said discrete regions being fixed with one species of capture molecules;
(b) performing a reaction leading to a metallic precipitate formed at the location of said binding;
(c) determining the possible presence of precipitate(s) in discrete region(s); and
(d) correlating the presence and/or the formation of the precipitate(s) at the discrete region(s) with the identification and/or a quantification of said target compound.

Abstract
The present invention is related to a method for the identification and/or the quantification of a target compound obtained from a sample, preferably a biological sample, comprising the steps of putting into contact the target compound with a capture molecule in order in order to allow a specific binding between said target compound with a capture molecule, said capture molecule being fixed upon a surface of a solid support according to an array comprising a density of at least 20 discrete regions per cm2, each of said discrete regions being fixed with one species of capture molecules, performing a reaction leading to a precipitate formed at the location of said binding, determining the possible presence of precipitate(s) in discrete region(s), and correlating the presence of the precipitate(s) at the discrete region(s) with the identification and/or a quantification of said target compound.

23. A diagnostic and/or quantification apparatus of a target compound obtained from a sample comprising:
-
(a) a solid support with an array surface comprising at least 4 discrete regions per cm2/surface, each of said region being fixed with one species of capture molecule corresponding to a target compound;
(b) a detection and/or quantification device of a metallic precipitate upon the surface of said solid support and resulting in a binding of said target compound upon a corresponding capture molecule;
(c) possibly a reading device of information(s) recorded upon said solid support;
(d) a computer programmed to;
(1) possibly recognize the discrete regions bearing capture molecules, (2) collect the results obtained from said detection and/or quantification device, possibly comparing with the information(s) obtained from said reading device; and
(3) carry out a detection and/or quantification of said target compound(s). - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
