SARS-CoV-2 Oligonucleotides

PentaBase is manufacturing oligonucleotides based on standard and proprietary DNA technologies

We are currently supplying our customers with oligonucleotides for SARS-CoV-2 PCR assays based on our proprietary INA® technologies including SuPrimers™ and HydrolEasy™ probes.

SuPrimers™

SuPrimers™ are PCR primers modified with our proprietary technologies. The benefits of replacing primers based on standard DNA with SuPrimers™ include increased signal-to-noise ratio as well as increased sensitivity and specificity towards their target sequences

HydrolEasy™ Probes

HydrolEasy™ probes are dual-labeled hydrolysis probes based on our proprietary INA® technologies. HydrolEasy™ probes provide increased signal-to-noise ratio and increased specificity and sensitivity toward the target sequence compared to standard TaqMan hydrolysis probes.
