A unique, powerful approach for safer and more effective complex genetic engineering
The Pin-point™ system offers a uniquely powerful approach to safer and more effective complex genetic engineering for the development of cell and gene therapies.
Would you like the opportunity to use base editing in the development of next generation cell and gene therapies? The Pin-point base editing system provides the specificity and predictability of base editing combined with the safety benefits of avoiding introducing double strand DNA breaks.
With the Pin-point platform, there is potential for multiplex gene editing capabilities, as well as for combining multiplex knockout and knock-in edits in a single intervention, making it an attractive technology for both cell and gene therapies.
We offer Pin-point base editing reagents and services, as well as licensing to the underlying patents and patent applications, to provide broad access to base editing across the research and therapeutic market.
In one possible configuration of the Pin-point platform, a catalytically modified nickase Cas9 (nCas9) is directed to the target site by a single guide RNA (sgRNA) that includes an extended RNA aptamer scaffold. The RNA aptamer recruits the deaminase (here shown as a cytidine deaminase) via the aptamer binding protein domain.
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.
Key benefits of the Pin-point platform include:
- Predictable, precise, and efficient single and multi-gene editing
Base editing efficiently converts target bases, as opposed to generating complex insertions or deletions. This means the cell populations have more homogeneous, predictable, and precise single base change outcomes compared to traditional CRISPR-Cas9. Single base changes can still introduce stop codons or splice site disruptions that can result in protein knockouts. - Simultaneous knock-in and knockout in a single intervention
The Pin-point platform uniquely allows for site-specific targeted knock-in of donor template sequences. Read more about it here: Porreca et al. Molecular Therapy, 2024. - Modular control over editing window to help reach targets of interest
Different configurations of the platform have been shown to achieve precise editing of target bases within the base editing window, avoiding unwanted bystander editing effects. Easily screen through nuclease, deaminase, and gRNA combinations to identify the configuration that achieves the desired editing outcome by leveraging our in-house resources or within your own pipeline. - Improved safety profile compared to standard CRISPR-Cas9
The Pin-point platform has been demonstrated to result in reduced cytotoxicity, fewer off-targets, and lower risk of genomic aberrations compared to other gene editing methods. - Proven high editing efficiencies in T Cells, iPSCs, and HSPCs
We provide protocol guidelines for precise and efficient multiplex and single-plex editing in clinically relevant cell types. - Nuclease and deaminase flexibility to optimize the system for your application
Our universal platform is compatible with Type II and Type V nucleases as well as a variety of deaminase variants [Scientific poster: Development of the Pin-point platform: a versatile base editing technology with broad Cas enzyme and deaminase compatibility well suited for Cell and Gene Therapy, Perez-Duran et al, 2024]. This allows for clinical adoption of base editing with the nuclease and deaminase best suited to your unique needs.
By democratizing access to base editing, the Pin-point platform can help you to accelerate the development of novel treatments and potential cures for genetic disorders.
