Alt-R S.p. Cas9 Nuclease Alt-R S.p. HiFi Cas9 Nuclease Alt-R S.p. Cas9 D10A Nickase Alt-R S.p. Cas9 H840A Nickase
Description Wild-type Cas9 with high genome editing potency that is simple to use and economical Cas9 variant with improved specificity based on reduced off-target effects, while preserving high on-target activity Cas9 variant with a mutation in the RuvC domain that disables cleavage of the non-target strand Cas9 variant with a mutation in the HNH domain that disables cleavage of the target strand
DNA cleavage Both strands Both strands Target strand Non-target strand
Suggested use First choice for most CRISPR genome editing projects Ideal for experiments sensitive to off-target events May be beneficial for homology-directed repair (HDR) experiments, but requires two suitable cutting sites within an optimal distance
Molecular weight 162,200 g/mol
Amount provided 100 μg or 500 μg
Concentration 10 mg/mL (62 μM) in 50% glycerol
Shipping conditions Dry ice
Storage conditions -20°C at stock concentration
Dilution Dilute in a medium (such as OptiMEM®) or Phosphate-buffered saline (PBS) before use

Minimize off-target edits with our HiFi Cas9 nuclease

Alt-R S.p. HiFi Cas9 Nuclease V3 facilitates near-WT editing potency while providing superior cutting specificity to reduce off-target editing.

Consistent, reliable CGMP manufacturing for therapeutic development

Expect the best from Aldevron’s ISO13485-certified manufacturing process. (A) Quality tests show no loss of purity or (B) protein activity when the Cas nuclease is stored under recommended conditions.
