Pin-point Base Editing Reagents

Accelerate therapeutic development with Revvity's Pin-point™ base editing reagents.

The modular Pin-point base editing platform combines engineered guide RNA, nickase Cas9, and a deaminase enzyme to deliver precise single-nucleotide edits in sensitive cell types, including T cells and iPSCs, without double-strand breaks. The system's modularity allows customizable configurations for both adenine (ABE) and cytosine (CBE) base editing.

With validated performance in T cells, iPSCs, and HSPCs, the Pin-point base editing platform delivers improved safety over standard CRISPR-Cas9 with multiplex editing capabilities.

Pin-point base editing reagents are available for research use only and are not for diagnostic use or direct administration into humans or animals. The Pin-point™ base editing platform technology is available for clinical or diagnostic study and commercialization under a commercial license from Revvity.

Pin-point base editing technology

Revvity's Pin-point base editing technology is a flexible, three-part system that uses an engineered guide RNA to bring all the pieces of the editing machinery together on-target in the genome.

A nickase Cas9 (nCas9) is guided to a specific DNA sequence by a modified guide RNA (gRNA). This gRNA includes an aptamer "handle", which acts like a docking site to recruit the editing enzyme (such as an ABE or CBE deaminase) via a matching binding protein.

By placing the recruitment function on the gRNA rather than permanently attaching the enzyme to Cas9, the system allows for greater flexibility. This means you can mix and match components, fine-tune activity, and even recruit multiple functions at once for more advanced genome engineering applications such as CAR-T cells generation.

System components

  1. Guide RNA (gRNA) with built-in aptamer "handle"
  2. Nickase Cas9 (nCas9) for target DNA recognition and strand nicking
  3. Effector protein (e.g., ABE or CBE deaminase) fused to an aptamer-binding protein for recruitment
The guide RNA directs the modified Cas9 to the precise location on the targeted DNA
The guide RNA directs the modified Cas9 to the precise location on the targeted DNA
Modified Cas9 nicks a single strand of the targeted DNA
Modified Cas9 nicks a single strand of the targeted DNA
The recruited deaminase performs the base edit on the opposite strand
The recruited deaminase performs the base edit on the opposite strand

Revvity's Pin-point base editing platform

The modular Pin-point base editing system facilitates highly efficient and precise nucleotide conversion with the potential for multiplex gene editing capabilities. The modularity of the system means we can offer a customizable, off-the-shelf system for base editing.

Reagents for the Pin-point base editing platform are now available in both Adenine base editing (ABE) and Cytosine base editing (CBE) configurations. View the product pages for more details.
