Depositor Comments

shRNA for use as a negative control. Sequence of hairpin is:CCTAAGGTTAAGTCGCCCTCGCTCGAGCGAGGGCGACTTAACCTTAGG. For packaging, please use pCMV-dR8.2 dvpr (Addgene plasmid #8455) and pCMV-VSVG (Addgene plasmid #8454).

Please note that the 5' cloning site, AgeI, is typically destroyed during the shRNA cloning. Depending on the specific shRNA sequence, the site can occasionally be restored. AgeI is present in this plasmid.

Viral Quality Control

Titering Method:
  • Colony formation assay: A549 cells were transduced with serial dilutions of 1864-LV and treated with puromycin. Puromycin-resistant colonies were expanded for approximately 2 weeks, stained with crystal violet, and counted.
  • PCR confirmation of insert: PCR was carried out with primers targeting the hU6 and PGK promoters. The PCR product was visualized on an agarose gel for size confirmation, purified and the shRNA sequence was confirmed by Sanger sequencing.
