Abstract

The invention relates to compositions and methods for multiplex decoding of microsphere array sensors.

Claims

1. A method of decoding an array, said method comprising:

a) providing an array comprising sites, said sites having a bioactive agent and a combination of different identifier binding ligands (IBLs) randomly distributed thereon;

b) adding a first decoder binding ligand (DBL) to the array, wherein the first DBL binds to an IBL in said combination;

c) identifying the position of the IBL that binds to the first DBL;

d) adding a second DBL to the array, wherein the second DBL binds to another IBL in said combination;

e) identifying the position of the IBL that binds to the second DBL; and

f) decoding the position of said bioactive agent on said array based on the position on the array of the IBLs that bind the first and the second DBLs.

2. The method of claim 1, wherein said combination of IBLs and said first and second DBLs each comprise nucleic acid.

3. The method of claim 2, wherein said nucleic acid is selected from the group consisting of DNA and RNA.

4. The method of claim 2, wherein said nucleic acid is single stranded.

5. The method of claim 4, wherein said nucleic acids are oligonucleotides of about 8 to about 40 basepairs in length.

6. The method of claim 1, wherein said sites comprise at least 10 IBLs.

7. The method of claim 1, wherein said first and second DBLs comprise a fluorophore.

8. The method of claim 1, wherein said array comprises glass or plastic.

9. The method of claim 1, wherein said array comprises a fiber optic bundle.

10. The method of claim 1, wherein said array comprises a flat planar surface.

11. The method of claim 10, wherein said flat planar surface comprises one or more depressions.
