L1000 Standard Operating Procedure May 2014 Connectivity Map Platform The Broad Institute
Overview
Protocol: Transcript Capture and Ligation Mediated Amplification In reverse transcription, mRNA transcripts from whole cell lysate or purified RNA are isolated by capturing the polyA tail of the transcript on the surface of a polyT coated turbocapture plate. Then the reverse transcriptase enzyme is used to build a cDNA complement to this polyT tail. Upstream and downstream probes containing gene specific, LUA “barcode” tags, and universal primer sequences are then added to the mix. The probes anneal and ligate to the gene specific region of the transcript. Finally, universal biotinylated primers are added to the mix and PCR amplified. The final product is biotinylated, barcoded PCR amplicon of 104-nt length.
Transcript Capture (CAP) Purpose
Immobilize mRNA from lysed cells onto the walls of the Turbocapture plate, by providing a dT coated surface which binds the poly-A tail of each mRNA transcript. RELATED PROTOCOL This step requires materials produced via the related protocol Cell Based Assay. Alternately, mRNA acquired by some other method can be used.
IMPORTANT Prepare materials and assets in pre-PCR and RNAse-free environment.

TIP:Take a second pass through the bead plate to recover as many beads as possible.
7. Add TE with recovered beads to Falcon tube.
