PBHR100A-1 SBI PiggyBac Ge

Without a trace—make seamless gene edits with no residual footprint—includes dual GFP/puromycin selection and on-target enrichment with TK selection

Overview

Seamless gene editing

Use the PiggyBac Gene Editing HR Targeting Vector (MCS1-5’PB TR-EF1α-GFP-T2A-Puro-T2A-hsvTK-pA-3′ PB TR-MCS2) to get seamless gene editing—leave no trace of vector sequences behind.

This special HR Donor works with the Excision-only PiggyBac Transposase instead of the Cre-LoxP system. Simply proceed with your CRISPR/Cas9 gene editing as usual—clone your homology arms into MCS1 and MCS2, use dual GFP and puromycin selection to find integrants, and enrich for on-target events using negative thymidine kinase (TK) selection (Figure 1).

 

Why use an HR targeting vector?

Even though gene knock-outs can result from DSBs caused by Cas9 alone, SBI recommends the use of HR targeting vectors (also called HR donor vectors) for more efficient and precise mutation. HR donors can supply elements for positive or negative selection ensuring easier identification of successful mutation events. In addition, HR donors can include up to 6-8 kb of open reading frame for gene knock-ins or tagging, and, when small mutations are included in either 5’ or 3’ homology arms, can make specific, targeted gene edits.
