Description
Cas9 Nuclease, derived from wild-type Streptococcus pyogenes, is an RNA-guided endonuclease capable of specifically cleaving double-stranded DNA (it can also cleave single-stranded DNA or RNA in the presence of DNA PAM). The Cas9 cleavage site is located within the target sequence, three bases away from the PAM (NGG) region. This product, through codon optimization and nuclear localization signal (NLS) design, is recombinantly expressed in Escherichia coli, exhibiting high editing efficiency.
Product Features:
- Optimized Core Positioning Signal: Enhanced NLS (Nuclear Localization Signal) for improved editing efficiency.
- Consistent Editing Efficiency: Consistent high editing efficiency both in vitro and in vivo.
- His Tag: His tag provides flexibility in fusion protein detection methods.
- High Purity: Purity exceeding 95%.
- High Concentration: Suitable for standard editing conditions and adaptable for optimizing editing conditions in challenging scenarios such as primary or embryonic cells, microinjection, or screening multiple gRNA sequences simultaneously.

Precautions
- To prevent RNase contamination, maintain a clean experimental area, wear clean gloves and masks during operation, and use RNase-free consumables such as pipette tips and centrifuge tubes.
- Avoid repeated freeze-thaw cycles. After initial dissolution, it is recommended to aliquot and store according to usage.
- For your safety and health, wear lab coats and disposable gloves during operation.
