Purity:  99.11%
Synonyms: bisBenzimide H 33258; H 33258
Hoechst 33258 is a blue to blue-green fluorescent live cell dye that can label DNA. Hoechst 33258 can specifically bind to the minor groove of DNA (and tends to bind to A/T-rich DNA), resulting in a significant increase in fluorescence intensity. Hoechst 33258 can cross the cell membrane and cause changes in DNA structure, such as G2/M phase arrest. Hoechst 33258 can bind to live or fixed cells, and the fluorescence intensity increases with increasing solution pH. As a DNA-specific probe, Hoechst 33258 can be used to detect DNA content, analyze cell cycle, etc. The excitation wavelength of Hoechst 33258 is 350-365 nm, and the emission wavelength is 460-490 nm .

BODIPY FL-DHPE is a fluorescent lipid probe composed of phosphatidylethanolamine (DHPE) labeled with a BODIPY FL fluorophore, which is used for fluorescent labeling of cell membranes, differentiation between liposome membrane fusion and endocytic pathways, and studies of membrane dynamics. The two C16 alkyl chains of BODIPY FL-DHPE insert into the lipid bilayer of membranes, and its fluorescence exhibits concentration dependence: it exists as monomers and emits green fluorescence at low mole fractions; it forms dimers with a red-shifted emission peak at high mole fractions; this spectral change is independent of enzymes, pH, and membrane potential. When liposomes enter the plasma membrane via membrane fusion, the dye is diluted, leading to attenuation of the dimer peak and enhancement of the monomer peak; when entry occurs via endocytosis, the dye remains in endosomes at high concentration with no change in the dimer peak, allowing differentiation between the two uptake pathways. Ex = 488 nm; monomer Em = 515 nm, dimer Em ≈ 620 nm .
