In NGS experiments, the library prep is a very important aspect of the entire workflow, as the quality of library prep will greatly influence the quality of the sequencing data.
But, next to the Library Prep, also the quality of the input material is crucial. In order to maximize the success ratio of your NGS experiments, we do offer 2 kits for RNA extraction and long-read cDNA amplification that result in high quality material to use in downstream Library Prep.
The SPLIT RNA Extraction kit offers fast and efficient extraction of RNA, free from Genomic DNA. The RNA can be recovered as total RNA or split into 2 fractions, large RNA and small RNA, enabling the efficient analysis of e.g. mRNA and miRNA from the same sample.
The obtained RNA is ideal for seamlessly preparing NGS libraries of total RNA or its large and small fractions or any other demanding downstream application. The dedicated SPLIT kit for Blood enables concomitant depletion of globin mRNAs from human blood samples in low volumes (50-250µl).
The extracted RNA has a high RIN quality score for all types of samples. A RIN of 10 and a 28S/18S rRNA ratio of 2.7 can be obtained from cell culture. Extractions from tissue samples usually result in RNA with a RIN of 8.0-9.5.
SPLIT RNA extraction enables efficient recovery of siRNA and miRNA down to 17nt in the total RNA or in the small RNA fraction. This has been shown in spike-in experiments with small RNA markers.
The highly optimized, phenol-extraction based protocol ensures negligible gDNA content in the extracted RNA sample, compared to conventional methods.
The SPLIT kit can be used for the extraction of either total RNA ( 17nt to 10.000nt) or for the isolation of the large RNA fraction (cut-off at ±150nt), with the option to obtain the small RNA fraction separately.
The SPLIT protocol does not require DNase-treatment which is often used for the removal of genomic DNA in the sample and can be a reason for degradation of the RNA. In addition, the SPLIT workflow does not use gDNA removal columns either. The function of those columns is based on size exclusion, which can impose a size bias on the extracted RNA as well.
The SPLIT RNA extraction kit for Blood includes an additional step which enables efficient depletion of predominant globin mRNA from human blood samples. This results in increased Gene Detection.

The SPLIT Rapid Viral RNA/DNA Extraction Kit enables the isolation of high-quality RNA & DNA from liquid samples using a fast, streamlined protocol. In just 15 minutes, the viral RNA is isolated. 24 samples can be done in just 25 minutes. No complex instrumentation or chemicals such as phenol are needed, as it is a sample lysis column-based purification workflow.
The SPLIT viral RNA extraction kit yields high-quality RNA suitable for reverse transcription, RT-qPCR, and targeted RNA-Seq. RNases are immediately activated when the sample is resuspended in the Isolation Buffer. For the analysis of viral RNA, the co-isolated genomic DNA does not have to be removed, and the DNA itself can be analysed in other applications.
The kit is validated for SARS-CoV-2 extraction from viral transport medium. Spike-in viral RNA can be extracted from media such as HBSS and PBS.
The Viral RNA extraction kit is also available in bulk format (400 reactions) and is transferable to magnetic beads for plate based, automated high throughput RNA extraction.
The TeloPrime Full-Length cDNA Amplification Kit V2 is an all-in-one protocol for generating full-length DNA from total RNA, based on Lexogen unique Cap-Dependent Linker Ligation (CDLL) and long reverse transcription (long RT) technology, and is highly selective for full-length RNA molecules that are both capped and polyadenylated.
The ligation of the 5’ linker to the end of the 3’ end of the cDNA is based on the Cap-Dependent Linker Ligation (CDLL) technology and happens in a highly cap-dependent manner. This provides an exceptional cap-specificity and eliminates cDNA products from degraded mRNA.
cDNA synthesis is based on the unique CDLL and Long reverse transcription (Long RT) technology from Lexogen. This makes TeloPrime highly selective for full-length RNA molecules that are both capped and polyadenylated.
The via TeloPrime generated full-length cDNAs can be used for a great variety of downstream applications (eg. NGS, RACE, cloning, microarray probes and normalization). This kit enables detection and correct quantifications of splice variants and their true transcription start- and end-sites, in both short and long mRNA molecules. For further full-length or gene-specific PCR’s, a TeloPrime PCR Add-on Kit v2 is offered, containing the PCR forward and reverse primer separately, enabling substitution with the gene-specific primer of interest.

TraPR (Trans-kingdom, rapid, affordable Purification of RISCs) is a column-based method for isolation of functional small RNAs from RNA-induces silencing complexes (RISCs). The TraPR RNA isolation kit only isolates fully functional, physiologically relevant silencing sRNAs and screen for novel sRNA in uncharacterised samples.
In just 15 minutes, TraPR RNA isolation kit purifies RISC fractions, even from challenging or inconsistent samples, cell types, tissues, and bio-fluids of any organism. There is no characterisation or knowledge needed of the organism of interest.
Samples such as plasma can be used with the TraPR kit, as it enriches sRNA and reduces the read count dispersion for low-abundant miRNAs. This provides precise quantification. The TraPR RNA isolation kit is therefore perfect for biomarker discovery.
This simple downstream analysis is cost efficient and can be used in many applications such as qRT-PCR, low molecular weight RNA blotting, sRNA cloning and for Next Gen sequencing sample preparation.
The TraPR RNA isolation kit can be used as stand alone or used in combination with the Small RNA Library Prep Kit (Cat. No. 052, 135).
