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.

BDL-E5
0 ImagesCat. No.: HY-D3525BDL-E5 is a fluorescent probe for detecting live induced pluripotent stem cells at the early reprogramming stage. Its detection mechanism involves specific binding to authentic reprogramming cells, which exhibit increased expression of pluripotency and epithelial genes and decreased expression of mesenchymal genes compared to non-reprogramming cells; it appears to co-localize more significantly with the Golgi complex than other organelle markers in reprogramming cells, and it does not require washing after staining to reduce background signals; fluorescence is generated upon binding to these early reprogramming cells, with positive cells appearing 7 days before iPS colonies are visible and stain positive for the conventional pluripotent marker TRA-1-60, and sorting BDL-E5-positive cells enriches populations that generate higher numbers and quality of iPS colonies. Its detection wavelength is Ex/Em = 578/599 nm.
