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.

Human Serum Albumin-FITC
0 ImagesCat. No.: HY-D3025Synonyms: HSA-FITCHuman Serum Albumin-FITC (HSA-FITC) is a green fluorescent probe prepared by covalent conjugation of FITC with human serum albumin (HSA), with excitation/emission wavelengths of 488/505-550 nm. Human Serum Albumin-FITC (HSA-FITC) can be used to track nanotube conjugates taken up via caveolae-mediated endocytosis initiated by Gp60 receptor binding, and can also non-covalently adsorb to oxidized multi-walled carbon nanotubes. Human Serum Albumin-FITC (HSA-FITC) is widely applied in macrophage imaging, scavenger receptor targeting, and hepatoma cell imaging.

No.: HY-D3104CAS No.: 2767443-23-0ERNT is a fluorescent probe for monitoring endoplasmic reticulum (ER) polarity and detecting endoplasmic reticulum stress (ERS) during the progression of dynamic liver injury. ERNT functions based on a donor-π-acceptor (D-π-A) structure with an intramolecular charge transfer (ICT) effect. ERNT has multiple excitation/emission pairs: for in vitro cell imaging, the green channel has Ex/Em = 488/500-550 nm, and the red channel has Ex/Em = 488/570-620 nm; for in vivo liver imaging, Ex/Em = 520/620 nm; for solvent optical tests, Ex = 470 nm, with the maximum emission peak at 548 nm in low-polarity toluene and 668 nm in high-polarity DMSO. ERNT can evaluate the efficacy of hepatoprotective interventions by detecting changes in ER polarity, and also exhibits excellent photostability and low cytotoxicity.
