    摘要: Provided herein is a large immuno-sorbent surface area assay (ALISSA) for the rapid and sensitive detection of botulinum neurotoxins (BoNTs) and anthrax toxin. This assay is designed to capture a low number of toxin molecules and to measure their intrinsic protease activity via conversion of a fluorogenic or luminescent substrate. Also provided herein are novel peptides that can be specifically cleaved by BoNT and novel peptides that are resistant to cleavage by BoNT. The combination of these cleavable and control peptides can be used for implementation of an exemplary ALISSA used to specifically detect BoNT enzymatic activity. Furthermore, the ALISSA as described herein may also be used in a column based format for use in a high-throughput system for testing large quantities of samples.

    摘要: Described herein is a bioluminescence resonance energy transfer (BRET) based system and method to monitor ternary complex formation in real-time in live cells with high sensitivity and accuracy. This system transfers energy simultaneously between a luciferase donor and intermediate and terminal acceptors, appropriately chosen to also enable transfer from the intermediate to terminal acceptor while minimizing contaminating signals. The system may also be adapted for quaternary complex detection by including a protein complementation assay (PCA) component. The system is broadly applicable to the detection of any protein ternary/quaternary complex such as those involving nuclear receptors, GPCRs, Receptor Tyrosine Kinase (RTKs), multimeric enzymes or structural proteins.
