Development of Novel Biosensors for Infectious Disease  and Cancer Research

Azad Lab sticker.png

Luciferase based biosensors:

Several different reporter fragment complementation-based strategies have been employed to interrogate protein-protein interactions , including split-luciferase schemes. The two halves of the luciferase protein are linked to two possible interacting proteins in this technique. When the two candidate proteins engage, the halves of luciferase complement each other, and luciferase activity is restored. We have used this technology to create a biosensor for a variety of applications, including  biosensors for apoptosome formation assay, LATS1 activity, YAP/TAZ interaction with TEAD, and SARS-CoV-2 Spike interaction with ACE2.

What we do

We create diverse luciferase-based biosensors to investigate various biological phenomena, including the dysregulation of signaling pathways in cancer and the interactions between host and pathogen in emerging infectious diseases.
