HTRF SARS-CoV2 nucleocapsid Detection Kit, 500 Assay Points

SARS-CoV-2 particles are detected in cell lysates using a sandwich immunoassay involving an anti-nucleocapsid monoclonal antibody, labelled with terbium-Cryptate or d2, ensuring assay quality, reproducibility, and signal quality. The specific HTRF signal generated is proportional to the amount of nucleocapsid proteins.

The assay protocol, using a 384-well small volume plate or a low volume 96 well plate (20 µL final), is described on the right. 16 µL of cell lysates or control are dispensed directly into the detection plate for detection by HTRF reagents. The antibodies labelled with HTRF donor and acceptor can be pre-mixed and added in a single dispensing step to further streamline the assay procedure (4 µL), or separately (2 µL).

Detection of recombinant SARS-CoV-2 nucleocapsid

16 µL of recombinant protein in lysis buffer #5 were dispensed into a low volume white microplate before the addition of 4 µL of the premixed HTRF anti SARS-CoV2 capsid detection reagents. The HTRF signal was recorded after 2h incubation at RT.
