ID Plasmid Purpose
60903pHRdSV40-dCas9-10xGCN4_v4-P2A-BFP Expressed a nuclease dead Cas9 tagged with 10 copies of the GCN4 peptide v4 and BFP. This plasmid is part of the SunTag system for gene activation
60904pHRdSV40-scFv-GCN4-sfGFP-VP64-GB1-NLSThe plasmid encodes a antibody that binds to the GCN4 peptide from the SunTag system, and is fused to a transcriptional activation domain VP64
60905pLV-sgCDKN1B#2 BFPA lentiviral plasmid that encodes both a sgRNA targeting CDKN1B and BFP
60906pHR-scFv-GCN4-sfGFP-GB1-NLS-dWPREThe plasmid encodes an antibody that binds to the GCN4 peptide from the SunTag system, and is fused to sfGFP and a NLS for imaging
60907pHR-scFv-GCN4-sfGFP-GB1-dWPREThe plasmid encodes an antibody that binds to the GCN4 peptide from the SunTag system, and is fused to sfGFP for imaging
