Patent ID: 8795967

Claim:
A system for decoding the position of one or more bioactive agents on an array, comprising: an array comprising a plurality of bioactive agents randomly distributed at sites of said array, wherein each of a plurality of said sites further comprises at least a first and a second identifier binding ligand (IBL), wherein said first IBL and said second IBL each comprise different nucleic acid sequences; a first decoder binding ligand (DBL) adapted to bind to the first IBL, wherein binding of the first DBL with the first IBL comprises a detectable signal indicative of the location of the first IBL; a second DBL adapted to bind to the second IBL, wherein binding of the second DBL with the second IBL comprises a detectable signal indicative of the location of the second IBL; and wherein the location of the first and second IBLs is indicative of the position of one or more bioactive agents on said array.
