Validated SREBP1 shRNA Lentivirus: High-titer shRNA lentiviral particles specific for human/mouse sterol regulatory element binding protein 1 (SREBP1/SREBF1). The shRNA has been validated to meet or exceed 70% SREBP1 knockdown efficiency using a specific fluorescence-based method that is more rapid and reliable than qPCR. The shRNA lentivirus is ultra-purified and concentrated to high-titer by PEG precipitation and sucrose gradient centrifugation, and ideal for transducing difficult-to-transfect cells including thawed and/or primary cells. Order a shRNA lentivirus set and receive lentivirus produced from mix of 2 independent shRNAs validated to knockdown the target gene (>70%) plus control lentivirus produced from mix of 2 scrambled shRNA constructs.

Key Advantages:
- Same Cost For Custom Lentivirus – You can receive any combination of reporter (GFP/RFP/Luc/None) and selection marker (puromycin/blasticidin) for this product, without additional cost, by contacting us. To view our complete list of shRNA vectors, click here.
- Superior knockdown – LipExoGen Validated shRNA Lentiviruses are produced using the third generation system and feature novel, optimized shRNA vectors which express a 19-20 bp shRNA, fluorescent (GFP or RFP) or luminescent (luciferase) reporter, and drug-selection marker (puromycin or blasticidin). Taking advantage of a proprietary prediction algorithm developed in-house, validated shRNA constructs are capable of delivering 70% or more knockdown efficiency with less off-target effects compared to longer or mixed-sequence shRNA/siRNAs.
- Superior validation – All of our pre-made shRNA constructs are validated in-house using a specific fluorescence-based method that is more reliable than traditional qPCR. The validation process leverages bicistronic expression of the target mRNA and fluorescent reporter to confirm the efficacy of the shRNA. As knockdown validation can be readout using basic fluorescence microscopy, this low-cost, streamlined approach allows us to provide a superior-quality product at a price comparable or less than the average competitor.
- Superior accuracy – Polyclonal shRNA-transduced stable cells can be established within 10 days and used for downstream applications while preserving more properties of the parental cells. In this way, high-efficiency knockdown from our validated shRNA lentiviral particles can be advantageous over sgRNA CRISPR-Cas9 systems which select for single cell clones.
- Easily identify transduced cells – Validated shRNA constructs contain both fluorescent reporter and drug selection marker, allowing the flexibility to select transduced cells by puromycin/blasticidin or FACS sorting of GFP/RFP. Luciferase reporters are also available for detecting transduced cells in vitro or in vivo using luminescence-based techniques.
Product Data
Figure 1. Knockdown validation for SREBP1-sh1-GFP-Puro. HEK293FT cells were co-transfected with human SREBP1-RFP bicistronic expression plasmid (red) and plasmids for the indicated shRNAs (GFP, green). After 24-36 hours, fluorescent images of the living cells were acquired by fluorescence microscopy. GFP represents transfection of the shRNA construct, whereas RFP indicates translation of the target mRNA. Higher knockdown efficiencies may be possible in stably-transfected cells. Sr-sh, scrambled shRNA.
Figure 2. Knockdown validation for SREBP1-sh2-GFP-Puro. HEK293FT cells were co-transfected with human SREBP1-RFP bicistronic expression plasmid (red) and plasmids for the indicated shRNAs (GFP, green). After 24-36 hours, fluorescent images of the living cells were acquired by fluorescence microscopy. GFP represents transfection of the shRNA construct, whereas RFP indicates translation of the target mRNA. Higher knockdown efficiencies may be possible in stably-transfected cells. Our “set” contains sequences sh1 and sh2. Sr-sh, scrambled shRNA.

Entrez Gene Summary | “This gene encodes a basic helix-loop-helix-leucine zipper (bHLH-Zip) transcription factor that binds to the sterol regulatory element-1 (SRE1), which is a motif that is found in the promoter of the low density lipoprotein receptor gene and other genes involved in sterol biosynthesis. The encoded protein is synthesized as a precursor that is initially attached to the nuclear membrane and endoplasmic reticulum. Following cleavage, the mature protein translocates to the nucleus and activates transcription. This cleaveage is inhibited by sterols. This gene is located within the Smith-Magenis syndrome region on chromosome 17. Alternative promoter usage and splicing result in multiple transcript variants, including SREBP-1a and SREBP-1c, which correspond to RefSeq transcript variants 2 and 3, respectively.
