Provided herein is a method of sample analysis. In certain embodiments, the method comprises: a) cross-linking protein of a cell using a first compound to produce a first cross-linked product comprising cross-linked protein, and RNA; b) contacting the first cross-linked product and a second compound under conditions by which an oligonucleotide portion of the second compound hybridizes to the RNA; c) activating a reaction the first and second compound, thereby covalently crosslinking the oligonucleotide to the cross-linked protein to produce a second cross-linked product; d) isolating the second cross-linked product using an affinity tag; and e) analyzing the isolated second cross-linked product. Compounds for performing the method are also provided.
