GeneHero™ Cas9 Nuclease
Powered by BiozRecombinant Streptococcus pyogenes Cas9 nuclease, purified from E. coli, is a great choice for genome editing applications in vitro or in vivo. Available in two versions, containing nuclear localization sequence (NLS), and either with or without a C-terminal 6× His-tag, at a concentration of 1 mg/ml. For optimal activity, use with GeneCopoeia’s CRISPR-Fectin™ Transfection Reagent.
All Cas9 nucleases are dissolved in storage buffer at 1 mg/ml.
GeneHero™ Cas9 Nuclease In Action
GeneHero™ Cas9 Nuclease (GE001 and GE003) in vitro cleavage of target DNA fragments and comparison with competitor’s Cas9 protein.
Figure 1. HUWE DNA fragments were used as template. Three different sgRNA targeting the HUWE gene were designed and pre-incubated with Cas9 proteins respectively for the cleavage assay. Cleaved DNA bands are indicated by red marks. Ct, uncut HUWE DNA fragment control.
Figure 2. Cas9 protein in vitro cleavage assay. HUWE DNA fragments were used as a template. The sgRNA targeting the HUWE gene was pre-incubated with Cas9 protein for the cleavage assay. The GeneHero™ Cas9 Nuclease (lane 3-5) and IDT Alt-R® Cas9 nuclease (lane 6-8) were serially diluted from 250 ng, 100 ng to 50 ng per reaction. Cleaved DNA bands are indicated by red arrows. Lane 1, assay with Cas9 only; lane 2, assay with sgRNA only.
Figure 3. GeneHero™ Cas9 Nuclease genome modification in HEK293 cell line. Cas9 nuclease was co-transfected with synthetic sgRNA into the HEK293 cells using CRISPR-Fectin™ Transfection Reagent. Three different sgRNAs targeting the HUWE gene were designed and transfected with Cas9 protein respectively. The HUWE fragments were amplified from genomic DNA and subjected to the T7 endonuclease I assay. Cleaved DNA bands are indicated by red arrows.
