Super Knock-in Cocktail

Super Knock-in Cocktail

Substance mix that transiently maximizes HDR efficiency and prevents off-target editing.
The Super Knock-in Cocktail is a specialized formulation designed to transiently enhance HDR efficiency during genome editing up to 93%. This mix significantly boosts the precise insertion of desired genetic sequences while minimizing unwanted off-target edits. This results in improved editing accuracy, higher success rates, and safer outcomes for genome editing experiments across diverse biotech applications.

Key features

Higher proportion of precise edits

Promotes a precise repair pathway, increasing the proportion of cells carrying the intended genomic modification.

Prevents off-target effects

Drastically reduces off-target editing, reaching 0% even in regions prone to off-target events.

Increased knock-in efficiency

Achieves a 5.4-fold median increase in precise knock-in efficiency compared to standard editing across 30 targets.

Simple workflow integration

Integrated by directly adding to CRISPR reagents and cell culture media, with no additional handling steps or protocol changes required.

Frequently asked questions

No. Our products are for research purposes only and are not approved for diagnostic or therapeutic applications.

The Super UniGuide works efficiently across all cell types. The Super Knock-in and Edit Selector Cocktail are currently optimized for human cells only. Mouse versions of both are in development and we expect them in a few months. Get in touch at crispr@clearcutbiolabs.com if you’d like to be notified when they’re ready for testing.
 If you work in another species, we’d like to hear from you. We’re keen to extend these products beyond human and mouse, and knowing which organisms labs actually need helps us decide what to develop next.

All CCBio products work with RNP editing using Cas9, HiFi-Cas9 and Cas9 nickase (D10A). The Super Knock-in Cocktail and Edit Selector Cocktail also support Cas12a; the Super UniGuide is a tracrRNA and so does not apply to Cas12a.
 Guides can be a crRNA:tracrRNA duplex or a fused sgRNA, delivered by electroporation or lipofection. The Super UniGuide is not compatible with sgRNA.
 The Edit Selector Cocktail enriches the proportion of edited cells by performing a second Cas9 edit after any knock-in, base or prime edit that alters the gRNA recognition site.

Yes. All three can be used separately or together, depending on what’s limiting your experiment.
