Performed a half reaction (total volume = 3uL), using 1uL of purified PCR product. Incubated at RT for 20mins and then placed reaction on ice. Transformed chemically competent TOP 10 cells (Invitrogen) and heat shocked at 42C for 30s. Added 250uL of RT S.O.C. medium and incubated at 37C, 200RPM. Plated cells on pre-warmed Kan50+X-Gal plates (plates from 20110726; X-Gal added ~30mins before plating cells). Incubated plates O/N, 37C. Results: Good number of white colonies (>30). Will screen each colony with both qPCR primer sets to see if we can differentiate between the two COX/PGS isoforms in these clones.
