Diphenylterazine (DTZ) is a bioluminescent agent. It produces very little background of its own, giving it an excellent signal-to-noise ratio.

QM-FN-SO3ammonium is a near-infrared (NIR) aggregation-induced emission (AIE) active probe capable of penetrating the brain barrier. It is utilized for in vivo detection of Aβ plaques. QM-FN-SO3ammonium offers an exceptionally high signal-to-noise ratio, strong binding affinity, and high-performance near-infrared emission.

AF647 DBCO is a bright far-red fluorescent dye featuring a dibenzocyclooctyne (DBCO) functional group, enabling copper-free click chemistry (SPAAC) for specific conjugation to azide-modified biomolecules. Retaining AF647’s high photostability and brightness, this dye provides excellent signal-to-noise ratio and sensitivity for live-cell labeling, tissue imaging, and in vivo tracking.

YH-APN is a high-performance APN-activatable near-infrared fluorescent probe. It offers high sensitivity, high selectivity, and rapid response. When administered through in situ spraying, it achieves an exceptional tumor-to-normal tissue signal-to-noise ratio. YH-APN specifically differentiates cancer cells with high APN expression from normal cells and can monitor cancer cell migration.

3-MeOARh-NTR is an activatable imaging probe characterized by high selectivity and stability, offering a high signal-to-noise ratio specifically for nitroreductase (NTR) detection. It serves as an efficient molecular tool for identifying endogenous NTR [1].

3-MeOARh-NTR chloride is a highly selective and stable activatable imaging probe specifically designed for the efficient detection of nitroreductase (NTR), exhibiting a high signal-to-noise ratio [1].

ODIPY Green 8-P2M is an innovative thiol-reactive fluorescence probe derived from the BODIPY fluorophore. Its fluorescence is significantly quenched by d-PeT and can be reactivated upon reacting with thiol, leading to an exceptionally high signal-to-noise ratio. This makes ODIPY Green 8-P2M valuable for detecting very low concentrations of protein in gels following SDS-PAGE [1].

CelRed nucleic acid gel stain 10,000× concentrate in water is a fluorescent dye used for nucleic acid staining, suitable for staining and detecting dsDNA, ssDNA, or RNA in agarose gels or polyacrylamide gels.

1) Non-toxicity: belong to flower-stem dye, easy to biodegrade, no carcinogenic toxicity. 2) High sensitivity: at least 100pg ssDNA or RNA can be detected, which is 25 ~ 100 times higher than EB staining. 3) High SIGNal-to-noise ratio: the sample fluorescence signal is strong, while the background signal is low. 4) Simple operation: like EB, the dye does not degrade in the prefabricated gel and electrophoresis process;The dyeing process after electrophoresis takes only 30 minutes without decoloring or washing, and can be observed directly with ultraviolet gel transmission or visible light transmission.
