Random Hexamer Primers are a mixture of oligonucleotides representing all possible 6 bp sequence combinations (dN6).
Random Hexamer Primers consist of a mixture of oligonucleotides representing all possible hexamer sequences. Random Hexamer Primers are commonly used for priming single-stranded DNA or RNA for an extension by DNA polymerases or reverse transcriptases.
During cDNA generation, random priming gives random coverage to all regions of the RNA to generate a cDNA pool containing various lengths of cDNA. Random priming is incapable of distinguishing between mRNA and other RNA species present in the reaction.

All of our products can be made with our proprietary and innovative INA™ technology that allows us to create oligonucleotides and oligonucleotide-based assays that are more robust with increased affinity, specificity and sensitivity compared to products based on standard DNA chemistry.
Our products are compatible with standard PCR and real-time qPCR instruments. Our INA™ technology is applicable to a wide range of oligonucleotide types including DNA oligos, PCR primers and probes, blocking oligonucleotides and NGS adapters. We guarantee superior quality and performance of our INA™ modified oligonucleotides.
NGS ADAPTERS
BASEBLOCKERS™
(SU)PRIMERS
FLUORESCENT PROBES
EASYBEACONS™ & HYDROLEASY™ PROBES
BASEPROBES™

EasyBeacon™ & HydrolEasy™ probes
PentaBase is offering high-quality, dual-labelled INA® modified probes with a broad range of different fluorophores and quenchers. We offer two types of proprietary, dual-labelled probes for real-time PCR; EasyBeacon™ probes for end-point analysis and hydrolyzable HydrolEasy™ probes for qPCR with the improved signal-to-noise ratio.
Intercalating Nucleic Acid®
PentaBase’s proprietary technology, Intercalating Nucleic Acid® (INA®), is a hydrophobic base analog that is incorporated into oligonucleotides without replacing any nucleotide in the oligonucleotide sequence. The integrated INA® enhances the stacking effect of the DNA helix, which increases the affinity, sensitivity, and specificity of the oligonucleotide.
BaseProbes™
BaseProbes™ is a universal master mix comprising one to four qPCR probes. The system combines the versatility of SYBRTM Green type detection with the multiplex capacity of molecular probes.
FLUORESCENT PROBES
PentaBase is offering a high quality dual-labelled DNA probes and improved DNA probes with a broad range of different quenchers and fluorophores.
NGS Adapters
Indexed PentAdapters™ for next-generation sequencing on Illumina and Ion Torrent sequencing platforms. Using PentaBase’s outperforming technologies, we have made indexed adapters ready-to-use and ready-to-ship, for the sensitive sequencing of multiplexed samples.
BaseBlockers™
BaseBlockers™ are short oligonucleotides modified with several pentabases to ensure tight and specific binding to a sequence that should be inhibited from working as a template. They are furthermore modified to ensure that they do not work as potential primers.
(Su)Primers
SuPrimers™ are DNA primers modified with our proprietary pentabases and compatible with all applications of your standard primers. SuPrimers™ can be used with all your standard reagents.
Fluorescent probes
PentaBase is offering a high quality dual-labelled DNA probes and improved DNA probes with a broad range of different quenchers and fluorophores.
Indexed PentAdapters™ for Next Generation Sequencing on Illumina and Ion Torrent sequencing platforms. Using our outperforming technologies, we have made indexed adapters ready-to-use and ready-to-ship, for the sensitive sequencing of multiplexed samples. Our portfolio includes both single and dual-indexed adapters, and we also produce customized and molecular adapters upon request.
