Detailed product information


Specific applications

ATCC Genuine Nucleics can be used for assay development, verification, validation as well as monitoring of day-to-day test variation and lot-to-lot performance of molecular-based assays.

It is suitable for use in RT-PCR or other RNA-based procedures.


Genomic RNA isolated from a preparation of cell lysate and supernatant from Chlorocebus (formerly Cercopithecus) aethiops kidney epithelial cells expressing transmembrane protease, serine 2 and human angiotensin-converting enzyme 2 (Vero E6-TMPRSS2-T2A-ACE2; VTA) infected with SARS-related coronavirus 2 isolate hCoV-19/USA/MD-HP47946/2023 (Omicron variant, lineage EG.5.1). This product was prepared using methods known to inactivate viruses.  This product can be used in PCR and other molecular biology applications.

Handling information

Handling procedure
  1. Thaw the vial at room temperature and immediately place on ice. Avoid exposing the RNA to repeated freeze-thaw cycles as it may result in degradation.
  2. Gently mix the sample to ensure an even distribution of material.
  3. Briefly centrifuge the tube before opening to ensure all liquid is at the bottom.
Handling notes
RNA is easily degraded. Take extra precautions against contamination by using new gloves and clean lab coats when working with RNA. Use only RNase-free lab materials when handling this product. Vortexing can damage the RNA. Gentle pipetting is highly recommended. Aliquoting is highly recommended to avoid multiple freeze-thaws, which can damage the RNA.
