Lincode siRNA reagents are an important tool for the study of long noncoding RNA (lncRNA); an emerging class of regulatory molecules whose roles are still being fully elucidated. The Lincode pre-designed human siRNA reagents benefit from expert siRNA design and proprietary dual-strand modifications for specificity. Simply search for your gene of interest and choose from the available product formats and quantities.


  • Pre-designed against 9801 characterized lncRNAs (NR_ and XR_ transcripts) in Mouse RefSeq v.65
  • Lincode siRNAs carry proprietary dual-strand chemical modifications to ensure optimal strand loading for the reduction of off-targets
  • SMARTpool reagent technology that targets multiple regions of the lncRNA to improve the likelihood of RNAi-mediated degradation

The importance of high-confidence siRNA reagents in lncRNA knockdown studies

lncRNA may be more difficult to silence than protein-coding genes due to:

  • Nuclear localization of the lncRNA, reducing availability to RNAi cellular machinery
  • Tertiary structure of the lncRNA, preventing siRNA access to the target region
  • DNA or protein binding to the lncRNA, preventing siRNA access to the target region

Available Product Formats

  • SMARTpool: A mixture of 4 siRNA provided as a single reagent; providing advantages in both potency and specificity.
  • Set of 4: Discounted price on the Set of 4 siRNAs targeting a single gene. NO PRIOR PURCHASE REQUIRED.
  •  Individual siRNAs: Select 1, 2, or 3 individual siRNAs per gene. Minimum purchase of four at the 2 nmol size.

Detection of effective lncRNA knockdown following application of Lincode siRNA


Knockdown of BDNF-AS1 in hNDF cells by Lincode SMARTpool and four siRNAs. All siRNAs were used at 25 nM, normalized and remaining lncRNA transcripts were detected with Solaris (sold under the Thermo Scientific brand) qPCR lncRNA Expression Assays and normalized to Non-targeting Control siRNA. Viability was assessed by resazurin assay.


Lincode modifications enhance function and reduce off-targets


Lincode siRNA effectively knocks down BDNF-AS1 lncRNA, but not the protein-coding transcript BDNF that is antisense to the lncRNA target. This indicates strand specificity of Lincode siRNAs and effectiveness of ON TARGETplus modifications. siRNAs were applied at the indicated concentrations to hNDF cells. BDNF-AS1 and BDNF transcripts were detected with Solaris qPCR Expression Assays and normalized to Non-targeting control siRNA. Viability was assessed by resazurin assay and normalized to Untreated.

Genomewide expression analysis demonstrates improved specificity of Lincode siRNA To detect subtle phenotypic changes that may arise from lncRNA knockdown, it is essential to incorporate strategies to prevent the off-targeting of protein-coding genes. Lincode siRNA reagents are synthesized with proprietary dual-strand modifications known as the ON-TARGETplus modification pattern which has been proven to reduce off-targets arising from microRNA-like activity of the antisense seed region of the siRNA. Two different siRNAs targeting the same lncRNA were synthesized with modifications that (a) block the sense strand only or (b) the ON-TARGETplus modification pattern which blocks the sense strand and includes an antisense strand seed region modification. While the target lncRNA was effectively silenced by all four siRNAs (arrows), the siRNAs synthesized with the ON-TARGETplus modifications demonstrated greatly reduced off-targets.

Robust qPCR assays are necessary for accurate determination of lncRNA expression levels

lncRNAs demonstrate lower and more variable expression than protein-coding genes. It is therefore highly recommend to determine lncRNA expression levels in your cells prior to knockdown experiments. Solaris qPCR expression assays are designed for sensitive detection of lncRNA and demonstrate high sensitivity and reproducibility. 50 ng of total RNA was converted into cDNA using the Maxima First Strand cDNA Synthesis Kit (#K1641). Gene expression levels were evaluated with Solaris qPCR assays. Cyclophilin B (PPIB) was used as a reference for typical mRNA expression. Standard RT-PCR cycling conditions resulted in initial Cq values ranging from 22 (PPIB in 293T cells) to 36 (BDNF-AS1 in HeLa cells). MLK7-AS1 lncRNA expression was not detectable in any of the cell lines tested. Cell lines include HeLa, HEK293T, Human Neonatal Dermal Fibroblast (hNDF).
