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.

Methyl Green Staining Solution (Chloroform-Extracted, 1%)
0 ImagesCat. No.: HY-DY2032Methyl Green Staining Solution (Chloroform-Extracted, 1%) is a basic dye stock solution with differential nucleic acid binding activity that distinguishes double-stranded DNA from RNA, and it can be used for assays related to nucleic acid distribution and DNA localization. Methyl Green Staining Solution (Chloroform-Extracted, 1%) functions by competitively binding to the phosphate groups of nucleic acids and stably binds to intact double-stranded DNA; RNA within the oocyte-specific ribonucleoprotein complex specifically binds to this dye, and RNase completely blocks this binding reaction. The nucleic acid recognition of Methyl Green Staining Solution (Chloroform-Extracted, 1%) depends on the size of the dye cation and the intact double-helical structure of DNA.

DiSBAC10
0 ImagesCat. No.: HY-125452CAS No.: 169211-45-4DiSBAC10 is a voltage-sensitive fluorescent probe used to study cell membrane electrical activity in FRET assays. In a resting polarized cell, DiSBAC10 resides on the outer leaflet of the membrane where it accepts photons from excited fluorescein-labeled proteins and re-emits the photons at a higher wavelength. Depolarization of the cell causes rapid translocation of DiSBAC10 to the inner leaflet of the membrane, thereby increasing the distance between fluorophores and reducing the FRET signal.
