Patent ID: 7553621

Claim:
A method of analyzing a support for at least one biological reaction, comprising: (a) bringing a support into contact with at least one first liquid sample comprising at least one group of identical biological recognition molecules so as to attach the recognition molecules to the support at the level of a recognition zone, such that the support is functionalized; b) bringing the functionalized support into contact with at least one second liquid sample comprising at least one labeled target biological molecule so as to attach the labeled target to the recognition molecules; (c) producing a first image of the support after the attachment of the labeled target showing detection spots; (d) separating the labeled target from the recognition molecules to which the labeled target is specifically attached; (e) producing a second image of the support after the separation in (d) showing detection spots; and (f) analyzing the first and second images to determine the specific attachments between the recognition molecules and labeled target by identifying true-positive and false-positive results by subtracting the detection spots present in the second image from the detection spots present in the first image.
