Observe SARS-CoV-2 live virus replication with the 3CLglowLive biosensor. The sensor has near-zero background fluorescence at baseline, and produces a green fluorescent protein in the presence of viral replication as measured through 3CL protease activity. This assay is ideal for researchers who need an obvious yes/no readout of viral replication.The assay is packaged in BacMam for expression in mammalian cells. BacMam provides even, near 100% transduction efficiency in HEK293 cells as well as expression in many other cells including A549s and HUVECs. Expression is easily titrateable to your experimental needs or to adjust assay sensitivity. This kit includes the 3CLglowLive sensor BacMam, 3CLpro enyme BacMam, and 500mM sodium butyrate in H2O.
