Abstract
Source: Rezaei, R., et al. Detection of SARS-CoV-2 Receptor-Binding Domain Antibody using a HiBiT-Based Bioreporter. J. Vis. Exp. (2021).
The video demonstrates the luciferase assay used to quantify luciferase-tagged proteins. The assay uses an engineered luciferase enzyme composed of a large fragment that binds with the small fragment, which is conjugated with a protein of interest. The bound subunits form an active enzyme that, in the presence of the substrate, releases a luminescent signal. This signal is then quantified using a luminometer.
Protocol
1. Production and evaluation of the HiBiT-RBD bioreporter Producing a sufficient quantity of HiBiT-RBD bioreporter Prepare for cell culture Prepare complete Dulbecco's modified Eagle medium (DMEM) containing 10% fetal bovine serum and 1% penicillin/streptomycin. Then, warm the media in a 37 °C water bath. Turn the biological safety cabinet (BSC) on and use 70% v/v ethanol for sterilizing the cabinet surface. Culture the cell line. <ol…
