Disclosed herein are methods for performing assays, including general functional assays, on a biological cell. The methods can include contacting a biological cell with a test agent for a period of time; lysing the biological cell while the biological cell is disposed within a sequestration pen located within an enclosure of a microfluidic device; and allowing RNA molecules released from the lysed biological cell to be captured by capture oligonucleotides linked to a capture object disposed within the sequestration pen of the microfluidic device. Each capture oligonucleotide can include a priming sequence that binds a primer, and a capture sequence. Each cDNA transcribed from a captured RNA can have an oligonucleotide sequence complementary to the captured RNA molecule, with the complementary oligonucleotide sequence being covalently linked to one of the capture oligonucleotides of the capture object. |
