TARGATT™ Plasmids

The TARGATT™ plasmids are required to generate the donor plasmid that will be used with our TARGATT™ Transgenic kits and TARGATT™ “attP” mice for site-specific transgene integration in mice. Applied StemCell offers a number of plasmids with a unique combination of promoters and multiple cloning site to meet your special needs, and to ensure robust transgene expression:

TARGATT™ 2 (CAG + Poly A)

TARGATT™ 3 (no promoter + MCS)
TARGATT™ 6.1 (CAG-L4SL-MCS-PolyA)
TARGATT™ 7 (PGK-MCS-PolyA)
TARGATT™ 8 (PCA-MCS-PolyA)
TARGATT™ 9.1 (PCA-L4SL-MCS-PolyA)

Make your own TARGATT™ site-specific knock-in mouse model for inducible gene expression, gene overexpression, reporter gene insertion, knock-down by siRNA, humanized models and other applications.

Application Notes

Scheme for Gene Knock-in using a TARGATT™ Plasmid

Goal: To insert a GFP reporter gene into HCT116 cell line using the TARGATT™ 6.1 plasmid

One million HCT116 cells were transfected with 5 ug of TARGATT™ 6.1-GFP plasmid (CAG-L4SL-GFP), and with or without 2.5 ug Cre-expression plasmid using Neon® electroporation transfection system. In the presence of Cre recombinase expression, the LoxP-4stop-LoxP is deleted and GFP reporter is expressed. In absence of Cre-expression, the GFP expression is silenced by the 4 stop codons in LoxP-4stop-LoxP cassette.

FAQs

Does it matter which way we clone into AST-3043 TARGATT™ 3 (no promoter + MCS) plasmid? In other words, 5’-3’ relative to the first attB?
