Fluorescent Dye
Fluorescence is a phenomenon of photoluminescence in luminescence. When an atom is irradiated by light, some electrons around the nucleus jump from their original orbitals to higher energy orbitals under the influence of light energy, i.e., from the ground state to the first or second excited single-line state, etc. Due to the instability of the first or second excited singlet state, the electron returns from the excited singlet state to the ground state accompanied by released energy, resulting in fluorescence.
Fluorescent dyes can be covalently bound or physically adsorbed in the structure of the substance. The fluorescence properties allow for the characterization, localization and quantitative analysis of the labeled object. Fluorescent dyes have shown great potential for the detection of proteins, nucleic acids, cells, and immunoassays, attributed to the advantages in non-radioactive contamination, simple experimental operation and easy observation.
Fluorescent dyes have penetrated many fields such as pharmacology, physiology, environmental science, and information science, as well as functional studies of proteins and drug screening.

HPsensor 2
0 ImagesCat. No.: HY-D3520CAS No.: 2484683-99-8HPsensor 2 is a fluorescent probe used to detect the surface hydrophobicity of proteins. The detection mechanism of HPsensor 2 relies on its amphipathic properties. The 2-methoxyethylamine substituents at positions 3 and 5 of its BODIPY core enhance water solubility, enabling it to interact with solvent-exposed hydrophobic regions on proteins. When it binds to these hydrophobic surfaces, the free rotation of the meso-aryl substituent is restricted, increasing molecular rigidity and reducing non-radiative deactivation, which results in a significant enhancement of fluorescence. HPsensor 2 exhibits weak but detectable fluorescence in aqueous environments, and its fluorescence is highly sensitive to changes in protein surface hydrophobicity (Ex/Em = 528/579 nm).

BOD-Tz-TMR
0 ImagesCat. No.: HY-D3418BOD-Tz-TMR is a fluorescent probe used for nitric oxide (NO) detection and atherosclerotic plaque imaging.BOD-Tz-TMR has a detection limit of 31 nM for NO. BOD-Tz-TMR functions via Förster resonance energy transfer (FRET) and bioorthogonal reactions, in which the tetrazine linker quenches fluorescence through the energy transfer to dark state (ETDS) mechanism. The interaction of BOD-Tz-TMR with NO triggers a ratiometric shift in fluorescence from BODIPY (Ex/Em: 488 nm/512 nm, green channel) to TMR (Em: 592 nm, red channel). BOD-Tz-TMR labels macrophages through a bioorthogonal reaction with BCN, enabling its targeted accumulation at atherosclerotic plaque sites to detect endogenous NO associated with lesion progression. BOD-Tz-TMR can be used in studies related to atherosclerosis.
