At Creative Diagnostics, we offer Quenchbody Generation Services to support sensitive and real-time detection of target molecules in various research applications. Quenchbodies are fluorescent labeled antibody fragments that are only fluorescent in the presence of their target due to low background fluorescence.Quenchbodies are made from specially labeled and engineered antibody fragments. We provide robust and reliable quenchers through antibody selection and site-specific labeling, structural optimization and functional characterization. Quenches can be used for diagnostics, imaging, or as biosensors to quickly and accurately detect your target.Quenchbodies can be used for diagnostics, imaging, or as biosensors to quickly and accurately detect your target.

Quenchbody fluorescence turn-on curve (Signal Turn-On Curve). The fluorescence labeled Quenchbody showed concentration-dependent fluorescence enhancement after binding to influenza virus NP protein. In the range of 0–1000 pg/mL, the fluorescence intensity increased rapidly. The minimum detection limit was 50 pg/mL, and the fluorescence signal was enhanced by more than 40 times, showing extremely high sensitivity and dynamic range. The above results verify the application potential of Quenchbody in one-step rapid antigen detection.
Simply put, the fluorescence it carries is "muffled" when it does not hit the target. Once it hits the target, the fluorescence immediately lights up, the signal is very clear, and the detection is very fast.
Almost all proteins, small molecules, peptides, etc. can be used. It is especially suitable for experiments that want to quickly quantify or high-throughput screening.
No, we will specially select the location of the label and the dye used to ensure that the antibody can still firmly grasp the target.
It has super high sensitivity and can detect targets at nanomolar levels or even lower concentrations. It is especially suitable for applications with high requirements.
Of course you can! We support fluorescent dyes of various colors to help you achieve multi-channel and multi-target simultaneous detection.
