D-Plex Small RNA-seq library prep kit for Illumina

Diagenode’s CATS small RNA-seq Kit utilizes the innovative “Capture and Amplification by Tailing and Switching” (CATS), a ligation-free method to produce DNA libraries for next generation sequencing from low input amounts of RNA.

  • Higher small RNA diversity
  • Excellent reproducibility with ultra low inputs down to 10 pg
  • Great performance on challenging samples
  • Straightforward protocol: either gel or magnetic bead-based purification for your choice
  • Read more

    CATS relies on polynucleotide tailing for capturing the 3’-ends of nucleic acids and the template switching ability of MMLV-RT to capture the 5’ ends for cDNA synthesis. This kit allows for generating Illumina compatible ready-to-sequence libraries from RNA inputs as low as 10 picograms in just few hours.

    Libraries retain strand specificity of origin. Unlike competing solutions, our CATS RNA-seq kit exhibits higher library efficiency versus ligation-based methods providing higher complexity from better template capture and minimal bias due to lower amplification requirements.

    Functional microRNA targetome undergoes degeneration-induced shift in the retina
    Chu-Tan JA et al.
    Background: MicroRNA (miRNA) play a significant role in the pathogenesis of complex neurodegenerative diseases including age-related macular degeneration (AMD), acting as post-transcriptional gene suppressors through their association with argonaute 2 (AGO2) - a key member of the RNA Induced Silencing Complex...

    Repeat RNAs associate with replication forks and post-replicative DNA.
    Gylling HM, Gonzalez-Aguilera C, Smith MA, Kaczorowski DC, Groth A, Lund AH
    Non-coding RNA has a proven ability to direct and regulate chromatin modifications by acting as scaffolds between DNA and histone-modifying complexes. However, it is unknown if ncRNA plays any role in DNA replication and epigenome maintenance, including histone eviction and re-instalment of histone-modifications aft...

    Small RNAs (smRNAs) are important regulators of many biologic processes and are now most frequently characterized using Illumina sequencing. However, although standard RNA sequencing library preparation has become routine in most sequencing facilities, smRNA sequencing library preparation has historically been chall...

    Circulating miRNA analysis for cancer diagnostics and therapy.
    Valihrach L, Androvic P, Kubista M
    Successful treatment of cancer depends on early diagnosis and effective monitoring of patients' response to therapy. Traditional tools based on tumor biopsies lack the sensitivity and specificity to capture cancer development in its early phases and are not applicable for continuous monitoring. To overcome these bar...

    The sncRNA Zoo: a repository for circulating small noncoding RNAs in animals.

    The repertoire of small noncoding RNAs (sncRNAs), particularly miRNAs, in animals is considered to be evolutionarily conserved. Studies on sncRNAs are often largely based on homology-based information, relying on genomic sequence similarity and excluding actual expression data. To obtain information on sncRNA expres...

    Circulating miRNAs are favored for biomarker candidates as they can reflect tissue specific miRNA dysregulation in disease contexts. Moreover, they have additional advantages that they can be monitored in a minimal invasive manner. Blood-borne miRNAs are therefore currently characterized to identify, describe and va...
