OriGene offers pre-made lentiviral shRNA plasmid kits containing 4 sequence-verified expression cassettes that target your gene of interest. Each lentiviral cassette contains three major functional elements: shRNA, a puromycin selection marker & a tGFP reporter. With a guaranteed knockdown of ≥70%, these kits and our ready-to-use lenti-shRNA particles are a great option for studying long-term gene knockdown.

pGFP-C-shLenti vector

  • Third generation Lentivector
  • Chloramphenicol marker for bacterial selection
  • Three major functional elements within the 5’LTR and 3’LTR. All of them can be packaged to viral particles and transduced to many cell lines.

The shRNA expression cassette

  • 29mer hairpin with a 7bp loop.
  • U6 driven expression
  • A Pol III termination sequence (TTTTTT) immediately downstream of the hairpin.
  • The gene-specific shRNA cassette is sequence-verified to ensure its match to the target gene.
