Biological Activity
Description
In Vitro
Recombinant 3CLpro is expressed in Pichia pastoris GS115 as a 42 kDa protein that displays a Km of 15 μM with Dabcyl-KTSAVLQSGFRKME-Edans TFA as substrate[1].
The Dabcyl-KTSAVLQSGFRKME-Edans TFA fluorogenic peptide is used as the substrate and the enhanced fluorescence due to cleavage of this substrate catalyzed by the protease is monitored at 538 nm with an excitation wavelength of 355 nm using a fluorescence plate reader[1].

Research Protocol for Infectious Diseases
Infectious-disease experiments test how pathogens interact with host barriers, innate immune receptors, inflammatory signaling, pathogen replication, and tissue injury; pattern-recognition receptors such as TLRs, RIG-I-like receptors, NOD-like receptors, and inflammasomes detect microbial molecules and activate NF-κB, interferon, and cytokine responses. The central hypothesis is that infection severity reflects the balance between pathogen burden and host response: protective inflammation restricts pathogen growth, whereas excessive or mislocalized inflammation contributes to tissue damage and disease phenotype. Unresolved questions include which host pathways are protective versus pathogenic, why some infection models fail to translate to human disease, and which combined readouts best predict clinically relevant infection outcomes.
