Backbone

  • Vector backbone
    lentiCRISPRv2 blast (Addgene #98293)
  • Backbone manufacturer
    Brett Stringer from Feng Zhang plasmid lentiCRISPR v2 (Addgene plasmid #52961)
  • Backbone size (bp) 10437
  • Modifications to backbone
    The first of the two MluI restriction sites of lentiCRISPR v2 (Addgene plasmid #52961) was mutated (to create lentiCRISPRv2 puro, Addgene plasmid #98290) to allow the subcloning of alternative P2A-antibiotic resistance cassettes between the BamHI and remaining MluI restriction site (see lentiCRISPRv2 hygro, Addgene plasmid #98291; lentiCRISPRv2 neo, Addgene plasmid #98292; and lentiCRISPRv2 blast, Addgene plasmid #98293). The Cas9-P2A-blast cassette of lentiCRISPRv2 blast (Addgene plasmid #98293) was removed by XbaI/MluI digestion and the blasticidin resistance gene sequence was cloned in its place between the XbaI and MluI restriction sites downstream of the EF-1alpha core promoter (see also lentiGuide puro, Addgene plasmid #104990; lentiGuide hygo, Addgene plasmid #104991; and lentiGuide neo, Addgene plasmid #104992).
  • Vector type
    Mammalian Expression, Lentiviral, CRISPR
  • Selectable markers
    Blasticidin

Growth in Bacteria

  • Bacterial Resistance(s)
    Ampicillin
  • Growth Temperature
    37°C

  • Growth instructions
    Single colonies of transformed STBL3 or STBL4 cells cultured in 5 ml of LB broth containing 100 micrograms/ml ampicillin for 20 hours at 37C, 200 rpm give good yields for plasmid minipreps.
  • Copy number
    High Copy

Resource Information

  • Supplemental Documents

    The blasticidin resistance gene sequence was amplified by PCR from pcDNA™6/TR (Invitrogen)
  • Terms and Licenses

Depositor Comments

This 3rd generation lentiviral plasmid expresses a S. pyogenes CRISPR chimeric RNA element with a customizable sgRNA from a U6 promoter and blasticidin resistance gene from an EF-1a core promoter.
This plasmid does NOT contain Cas9. It should be used in conjunction with lentiCas9 puro, lentiCas9 hygro or lentiCas9 neo or with cell lines expressing Cas9.
After cloning a double-stranded oligonucleotide specifying a gRNA between the two BsmBI restriction sites, use hU6-F (5'-GAGGGCCTATTTCCCATGATT-3') or LKO.1 5’(5'- GACTATCATATGCTTACCGT-3') to sequence the chimeric RNA element.
Instruction for gRNA double-stranded oligonucleotide design and cloning can be found in the Zhang lab protocol, https://media.addgene.org/data/plasmids/52/52961/52961-attachment_B3xTwla0bkYD.pdf
