  • Cas-tone- H3 inserts into MV12 (MV11-GFP)


Cas-tone Project

  • STAGE 1 - pcDNA-dCas9-VP64 vector re-design
    • DONE - Knock-out VP64 from C-terminus - replace AscI-VP64:HA:STOP-EcoRI-XbaI with AscI-HA:STOP-XbaI dsOligo
    • DONE - Knock-out FLAG from N-terminus - replace SpeI-CMV:3xFLAG:NLS-SacII with PCR-amplified (SpeI)/XbaI-CMV-SpeI-NotI-SacII; use reverse primer to add SacII
  • STAGE 2 - Histone parts
    • DONE - Order primers (annotated in Benchling)
    • DONE PCR-amplify histone parts as XbaI-Kozak-histone part-a-NotI. Note: Do no use Kozak BioBrick, since this will add extra amino acids onto conserved histone N-terminal tail. Instead, use the Kozak-like seq. from the Addgene plasmid, +3 extra Kozak bases (included in primer)
  • STAGE 3 - Cas-fusion
    • Insert Kozak-histone parts (X/N) into dCas9 plasmid "MV12" (S/N)
  • STAGE 4 - gRNA
    • Put pre-existing gRNA (from luc experiment) into pSPgRNA
