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.

TPE-Ph-In
0 ImagesCat. No.: HY-D3148CAS No.: 1804107-88-7TPE-Ph-In is a mitochondria-targeted voltage-sensitive probe that can be used for mitochondrial membrane potential detection, mitochondrial imaging of animal and plant cells and tissues, mouse sperm activity indication, and detection of mitochondrial membrane potential changes associated with early apoptosis. TPE-Ph-In is non-fluorescent in solution, but emits strong fluorescence when aggregated via restriction of intramolecular rotation/movement, and its fluorescence intensity is directly correlated with local probe concentration or mitochondrial membrane potential level. TPE-Ph-In can penetrate cell membranes, target mitochondria through charge-dependent accumulation, has low cytotoxicity and high photostability, and enables super-resolution imaging of plant mitochondrial fission, fusion and cristae structures. The excitation wavelengths of TPE-Ph-In include 450 nm, 488 nm, and 489 nm, while its emission wavelengths include 551-661 nm, 660 nm, and 694 nm. TPE-Ph-In can be used for studies on mitochondrial dysfunction associated with early apoptosis.

P2-Aggregate
0 ImagesCat. No.: HY-D3112P2-Aggregate is a polarity-sensitive fluorescent probe for protein aggregation, which is based on the Nile Red scaffold and modified with a morpholine ring to enhance water solubility. P2-Aggregate improves anti-precipitation ability in aqueous phase via morpholine ring modification, and enables site-specific labeling of target proteins by combining with HaloTag technology. Utilizing the property that its emission wavelength blue-shifts with decreasing local polarity (excited at 543 nm), P2-Aggregate quantitatively detects changes in local polarity during protein aggregation and polarity heterogeneity inside aggregates in living cells. P2-Aggregate can be used in the research of diseases associated with the aggregation of Htt-110Q and SOD1 proteins, such as Huntington's disease and amyotrophic lateral sclerosis.
