When you order an shRNA lentivirus set, you receive 2 different knockdown-validated shRNAs against your gene of interest, plus

2 different scrambled shRNA controls

 

Only $1195

 

We are the only company providing this level of validation for their shRNA! 



High Transduction Efficiency

 

5×10^6 Transduction Units (TU)/mL for fluorescent (GFP or RFP) lentiviruses and 2×10^6 TU/mL for lentiviruses with luciferase

 

 

Easy Stable Cell Lines

 Example of lentiviral transduction efficiency for human FASN shRNA lentivirus with RFP reporter. HEK293FT cells (2×10^5, 24-well plate) were transduced with 20 μl of hFASN-sh-RFP-BSD lentiviral particles for 48-72 h (Catalog No. LSV-0012-2S).

Fluorescent and Luminescent Reporters

 Example of lentiviral transduction efficiency for Scrambled shRNA control lentivirus with GFP reporter. HEK293FT cells (2×10^5, 24-well plate) were transduced with 20 μl of Scr-sh-GFP-Puro lentiviral particles for 48-72 h (Catalog No. LSV-0024-1S).

Adherent or Floating Cells – Detect on Flow

Example of transduction efficiency on floating cells. Jurkat cells (2×10^6) were transduced with 20 µl of Scr-sh-GFP-Puro lentiviral particles and GFP was detected on flow 3 days later to determine transduction efficiency (left). Dotted line represents uninfected Jurkat cells. The cells were selected using puromycin (1 µg/ml) for 3 days and then measured again on flow (right). Transduced cells can also be isolated using FACS.


Key Advantages

  • 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.

 Innovative Knockdown Validation: Have Full Confidence in Your shRNA 

 

We use our proprietary fluorescence-based shRNA validation system to deliver superior shRNA products at competitive prices 

 

Example of our fluorescence validation assay for knockdown of mouse PD-L1 gene

  • Example of our fluorescence validation assay in action shown in the image to the right (below on mobile).
  • The shRNA construct contains a fluorescent reporter allowing the researcher to detect transduced cells by flow or isolate them with FACS.
  • Validation is performed in HEK cells by co-transfection with (1) the shRNA construct and (2) an expression construct for the gene of interest and a different fluorescent reporter, separated by P2A.
  • In the example image, GFP shows the cells that have taken up the shRNA construct, and RFP indicates translation of the target mRNA.
  • The assay shows that the shRNA is capable of at least 70% knockdown of mouse Pdl1.
  • With LipExoGen, all orders for custom shRNA lentivirus are knockdown validated like this.
  • When you order a set (Option 1), both shRNAs are validated to knockdown 70% or more in our assay. Compare that to your ordinary 3+1 deal. Scrambled control lentivirus is also included in the Option 1 price, and is made with a mix of 2 independent scrambled shRNA constructs for high scientific rigor.
  • Our proprietary validation process is faster and less expensive compared to qPCR which allows us to charge less for a superior service. 

Advantages of TetOn shRNA

  • Scientists are eager to advance their research projects on gene functions as quickly as possible while achieving their desired goals. Two fundamental steps are overexpressing and/or knocking out/down the target gene in specific cells. Traditional methods, such as transient transfection of gene ORF, siRNA, miRNA, or sgRNA, often fail to yield accurate results, especially when the gene exhibits minor differences. This is due to factors like transfection efficiency, genomic integration at different sites, and significant variations between targets and controls, which can obscure the truth.

    To address these issues, LipExoGen scientists have developed several strategies:

    1. Creation of lentiviral systems for ORF cDNA, shRNA, and sgRNA: These systems can generate high-titer transducing lentiviruses, surpassing the capabilities of nearly all currently tested lentiviral vectors. This approach aims to eliminate the variability in transient transfection efficiency and establish stable polyclonal pools for experiments within just seven days post-transduction.

    2. Development of TetON-ORF cDNA and TetON-shRNA systems: These systems enable more accurate functional analysis of genes by avoiding the differences in genomic integration seen in individual clones, and by eliminating the need for corresponding controls.

    3. Optimization of shRNA design: LipExoGen scientists have established the best criteria for designing shRNA, considering not only the sequence but also the loop structure. This leads to the creation of highly efficient shRNAs quickly, surpassing the limitations of current design rules.

    4. Creation of lentiviral vectors for ORF cDNA and shRNA: These vectors feature different tags, a variety of fluorescent and luminescent reporters, and multiple selection drugs, combined effectively for high expression levels that meet researchers’ needs.

    5. Development of compatible lentiviral vector systems: These systems have interchangeable cloning sites in every component or cassette, allowing for the most efficient, exchangeable, and rapid construction of plasmids to fulfill customer requirements.
