pRNATin-H12/Retro 载体

pRNATin-H1.2/Retro siRNA expression vector is compatible with Clontech Retro-X Expression System. It uses an inducible H1 promoter for siRNA expression. The promoter contains the tetracycline operator (TetO1). As a competitor, tetracycline or doxycycline can bind this operator to remove the blockade of tetracycline repressor (TetR) from H1 promoter and induce the transcription of siRNA.

The vector also carries a neomycin resistance gene for establishing stable transfection cell line and a cGFP marker for tracking transfection efficiency, both genes are under the control of SV40 promoter. The vector uses CMV enhancer/promoter joined MSV 5’LTR (CMV/MSV 5'LTR) and MSV 3'LTR for viral transcription and packaging.
