OmicsLink™ shRNA Clone Collections

20% off shRNA



OmicsLink shRNA clone collections include lentiviral and non-viral vector-based shRNA constructs against genome-wide human, mouse and rat genes. shRNA of varying lengths (19 to 29 bases) were designed using a proprietary algorithm to make shRNA expression constructs that have high knockdown efficiency with minimal off-target effect.

Guaranteed shRNA knockdown

A set of four expression constructs is offered against every target gene with the guarantee that at least one of the four will have a knockdown effect of 70% or more on corresponding gene expression as determined by qRT-PCR, otherwise the constructs will be replaced one time free of charge. For more about our guaranteed shRNA knockdown, refer to warranty and cancellation policy here.

All cell types covered

Lentiviral and non-viral vector options allow transfection or transduction of shRNA into difficult-to-transfect cells as well as more conventional cell lines.

Multiple delivery formats

shRNAs are delivered as 4 individual constructs of 5 µg purified plasmid. Lentiviral particles for shRNA are also available as a custom service. Request a quote for custom shRNA lentivirus production service here.

Markers and reporters

Vectors with mCherry or eGFP reporter genes for monitoring transfection or transduction efficiencies. Stable cell selection with puromycin marker.

Fully sequenced expression cassettes

Expression cassettes of all shRNA clones are fully sequenced including the promoter, sense and antisense target sequences, hairpin, terminator, and other linker sequences.


Lentiviral and non-viral expression vector-based shRNA clones

Single gene down-regulation — The knocking down (KD) effect of the shRNA clones for a single gene can be studied and compared with that of a scrambled nucleotide control clone which is included for free with every shRNA clone order.

Pathway analysis — Genes have been grouped into various signal transduction, metabolic, and disease pathways and associations, as well as gene families and groups. By arraying the shRNA clones of known pathway(s) in 96 or 384 well plates, the role for a group of genes can be studied in a pathway. Large collections of shRNA clones against the human kinome are available, and can be grouped according to the functionality of each kinase.

Validation studies — The OmicsLink™ expression ready ORF cDNA clones together with the same ORF clones that contain silent mutations in shRNA target sequence regions can be used for shRNA validation studies and gene/protein functional rescue studies for genes/proteins targeted by corresponding shRNA.

Measurement of knockdown (KD) effect by vector-based shRNA clones


qRT-PCR — Targeting of the corresponding mRNA by a shRNA expression cassette leads to cleavage and degradation of the mRNA and possible subsequent reduction of protein expression. qRT-PCR is recommended as the first step in measuring KD effect. Validated qRT-PCR primers for corresponding target genes (and any other published transcripts) are also available.

Western blot analysis — Protein down-regulation is required in most cases for gene KD studies which can be assessed by western blot analysis.

Functional assays — The shRNA knockdown effect can be studied by end-point biological and biochemical assays such as cell proliferation, colony formation, cell cycle analysis, and migration based on the potential role played by each gene /protein.

Functional assays by a reporter gene/protein — Alternatively, when the endogenous transcript level of gene of interest is low and/or when qRT-PCR and western blot analysis is not feasible or possible, KD effect can be measured by co-transduction of shRNA clone with an expression clone plasmid which is transcribed into a chimeric mRNA transcript consisting of a reporter gene and the target gene ORF. The reporter gene encodes a reporter protein enzyme that can be used in functional assays. The destruction of the target gene mRNA by targeting shRNA results in the degradation of the reporter gene and, therefore, translation reduction of reporter protein enzyme. The KD effect can be quantified by the reporter enzymatic assays as illustrated by an example in figure 3 below.

Validation of shRNA against human kinome members

Figure 3. Validation of shRNA against human kinome members using vector-mediated (psi-sH1) shRNAs and CMV driven expression clones (in psiCheck-AP) that contain target kinase ORFs and express alkaline phosphatase (AP) for colorimetric assays. A. In the absence of shRNA, AP is expressed and its activity is quantified by colorimetric assay. B. Co-transfection of shRNA and AP-ORF expression clones, chimeric mRNA for AP-ORF is destroyed and, subsequently AP translation and its activity is reduced.
