The Bio-Rad SARS-CoV-2 ddPCR Kit is a powerful diagnostic tool in the battle against COVID-19, with sensitivity and precision beyond that of qPCR assays.

Combines the flexibility you need in your workflow and outstanding performance to deliver reliable results that your clinical laboratory demands.

No dark room required; fluorescence observation can be performed anywhere.

Hellma Analytics reference materials for UV/Vis spectrophotometry meet internationally recognized standards (Ph. Eur., USP, DAB, GLP, DIN ISO 9001, ...) and provide the basis for safe and reliable measurement results.

The kit is suitable to extract poly(A) RNA from 480 µg of total RNA input (96 reactions with 5 µg total RNA each).

Gibson Assembly® allows for successful assembly of multiple DNA fragments, regardless of fragment length or end compatibility.

SARS-CoV-2, which causes the global pandemic coronavirus disease 2019 (Covid-19), belongs to a family of viruses known as coronaviruses that are commonly comprised of four structural proteins. One of the proteins, SARS-CoV-2 Spike Protein (S Protein), is a glycoprotein that mediates membrane fusion and viral entry, and as such is a crucial COVID-19 target.  R&D Systems SARS-CoV-2 Spike range of bioactive proteins are valida…
