Super UniGuide

Super UniGuide

Achieves higher cleavage efficiencies and allows editing of difficult targets.
Our improved guide RNA backbone offers increased cleavage efficiency, enabling efficient editing of virtually any target, including challenging ones. With a modified sequence and vast chemical modifications, it ensures consistently strong performance and works across all cell types. Supplied as a universal tracrRNA, it seamlessly pairs with crRNA from any gRNA supplier of your choice.

Key features

Enables editing of difficult targets

The improved tracrRNA sequence enhances CRISPR activity, allowing cleavage at challenging or previously uneditable targets.

Higher cleavage-driven editing efficiency

Delivers higher editing efficiency through improved cleavage, achieving up to 1000-fold with a mean increase of 7.4-fold across different targets.

Simple workflow integration

Used as a direct replacement for standard tracrRNA, requiring no protocol changes or additional optimization steps.

This kit is available for testing

Try our solutions in your lab and assess their impact on your editing outcomes. Early testers get hands-on access before launch and direct support from our team.

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.
