New England Biolabs Expands its Luna® Portfolio with the SARS-CoV-2 RT-qPCR Multiplex Assay Kit
This new research use only kit enables high throughput multiplex detection of SARS-CoV-2 nucleic acid, supports increased sample input and reduces background amplification from possible contaminating genomic DNA.
IPSWICH, MA (January 12, 2021) — New England Biolabs® (NEB®) today announced the launch of its Luna® SARS-CoV-2 RT-qPCR Multiplex Assay Kit for real-time detection of SARS-CoV-2 nucleic acid. This research use only (RUO) kit offers multiplex testing of up to 94 samples in a single 96-well plate, with the additional capacity for supporting sample pooling and high throughput applications using 384-well plate test formats.
“With the increased demand for high throughput detection of SARS-CoV-2 to advance critical COVID-19 research, there still remains gaps with existing solutions, including the need for updated internal controls and an ability to increase overall assay throughput,” said Steven Chiu, Product Marketing Manager, DNA Amplification, at NEB.
“To address this, we specifically developed the Luna SARS-CoV-2 RT-qPCR Multiplex Assay Kit by modifying the Centers for Disease Control and Prevention (CDC)-designed RNase P control reverse primer to avoid spurious amplification of human genomic DNA. We also provide an optimized 4X master mix, which allows for increased sample input and pooling,” said Chiu. “With these enhancements, the kit achieves strong multiplex detection with 24 hours of room temperature stability.
The Luna SARS-CoV-2 RT-qPCR Multiplex Assay Kit offers multiplex detection of two separate regions of the SARS-CoV-2 virus N gene (N1 and N2), in addition to the human RNase P gene internal control, based on sequences provided by the CDC. The probes have been modified to detect N1 and N2 via two different fluorophores — HEX and FAM respectively — for simultaneous fluorescence detection on two different channels of a real-time instrument. Amplification of the internal control is observed in the Cy5 channel. N-gene targets present in this kit do not overlap with the variants present in the B.1.1.7 strain that was first detected in the United Kingdom, enabling detection of this strain. NEB continues to monitor variants that are detected around the world to ensure ongoing compatibility with primer/probe sets.
To reduce the risk of carryover contamination between reactions, the master mix includes dUTP and a unique, thermolabile UDG that offers significant benefits over the standard E. coli UDG. A universal passive reference dye is utilized, which is compatible across a variety of instrument platforms including those that operate in No ROX, Low, or High ROX reference signal conditions. An inert, blue tracking dye is also included for monitoring reaction setup. This visible dye does not overlap spectrally with fluorophores commonly used in qPCR and does not interfere with real-time detection.
