US Patent 8481698 Parallel proximity ligation event analysis

The present invention describes compositions and methods showing that the spatial proximity of intracellular components may be related to their ability to cooperate in intracellular biochemical reactions. In some embodiments, the present invention contemplates a variety of nucleic acid barcoded binding partners capable of determining the spatial proximity of intracellular components as determined by ligation of their respective nucleotide barcodes. As such, an intracellular component contact map may be constructed to fingerprint specific physiological and/or pharmacological intracellular conditions.
