SBI HR100PA-1 Basic HR Target

Knock-in any expression cassette to a specific genomic location with this basic HR targeting vector

Overview

Get precise genomic integration of your expression cassette

Use the PrecisionX^TM Basic HR Targeting Vector for Gene Knock-In/Out (MCS1-LoxP-MCS2-MCS3-pA-LoxP-MCS4) to insert any expression cassette into a specific location of the genome for both gene knock-ins—i.e. to express a gene-of-interest from a specific location such as the AAVS1 Safe Harbor Site—and gene knock-outs—i.e. to knock-out a gene by inserting specific sequences such as a GFP reporter cassette.

The Basic HR Targeting Vector for Gene Knock-In/Out (MCS1-LoxP-MCS2-MCS3-pA-LoxP-MCS4) features four different MCSs—clone your homology arms into MCS1 and MCS4, your expression cassette into MCS3, and any additional sequences such as small RNAs that don’t need a polyA tail into MCS2—as well as two LoxP sites that can be used to remove the expression cassette after it is no longer needed (learn more about Cre-LoxP excision here).

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.
