one qPCR assay instead of two or more

SARS CoV-2 + Alpha-Delta qPCR assay for screening and simultaneous VoC detection

Our new ALPHA-DELTA-Screening assays combines dual target SARS-CoV-2 detection with VoC determination of the two most relevant VoCs ALPHA and DELTA that make up > 99% of the strains in most countries of the world (see: The assay is based on a highly robust detection SARS-CoV-2 using the CDC / WHO recommended N-Gene assay and detects the Delta and Alpha strains via assays that are highly specific for mutations each strain.

Our ALPHA-DELTA Screening Assay combines:

  • Dual Target SARS-CoV-2 detection and simultaneous detection of the Alpha and Delta VoC

  • Screens for SARS-CoV-2 while simultaneously detects the two most relevant VoCs, Delta and Alpha which represent > 99% of samples in most countries in Europe and in USA.

  • The assay includes the WHO-recommended N1 gene in addition to highly robust detection assays for deletions present in the Alpha and in the Delta VoC.

  • Each positive sample is detected with two targets (dual target assay) required for a secure diagnostics

  • Sampling- or positive control is included for highly reliable assay conditions
