  • Vector backbone
    B52 (MLM3636 plasmid backbone modified to express 2 sgRNAs)
  • Backbone size (bp) 2633
  • Modifications to backbone
    The B52 plasmid is a derivative of the MLM3636 construct (Addgene #43860). B52 contains a second sgRNA-expressing cassette, which was PCR amplified from the plasmid eSpCas9 (1.1) (Addgene #71814) and cloned into the MLM3636 plasmid using the restriction enzymes HindIII and XhoI. The final B52 plasmid contains a ColE1 origin, an ampicillin resistance gene and two sgRNA expression cassettes with either BsmBI or BbsI sites for sgRNA cloning.
