METHODS FOR PREPARING HYBRID SUBSTRATES COMPRISING DNA AND ANTIBODIES AND USES THEREOF

摘要

The invention provides substrates that have antibodies and aptamers bound thereto. The invention also provides methods of detecting target analytes in a sample comprising detecting binding of a target analyte to capture probes on a substrate, wherein some of the capture probes comprise antibodies and other capture probes comprise aptamers, and all of the capture probes are bound to the substrate. In addition, the invention provides substrates that have capture probes and capture oligonucleotides bound thereto, wherein the capture oligonucleotides can hybridize to DNA barcodes. The invention also provides methods of detecting target analytes in a sample comprising contacting the sample with a substrate that has capture probes and capture oligonucleotides bound thereto.
