Cytoplasm Dyes

CFDA-SE is a fluorescent dye that can penetrate the cell membrane. It can react with the free amine group in the cytoskeleton protein inside the cell, and finally form a protein complex with fluorescence. After entering the cell, CFDA-SE locates in the cell membrane, cytoplasm and nucleus, and the fluorescence staining is strongest in the nucleus. CFDA-SE dye can be uniformly inherited by the cells with cell division and proliferation, and its attenuation is proportional to the number of cell divisions. This phenomenon can be detected and analyzed by flow cytometry under the excitation light of 488 nm, and can be used to detect the proliferation of cells.

Dihydroethidium, also known as DHE, is a peroxide indicator. Dihydroethidium penetrates cell membranes to form a fluorescent protein complex with blue fluoresces. After entering the cells, Dihydroethidium is mainly localized in the cell membrane, cytoplasm and nucleus, and the staining effect is the strongest in the nucleus. Dihydroethidium produces inherent blue fluorescence with a maximum excitation wavelength of 370 nm and a maximum emission wavelength of 420 nm; after dehydrogenation, Dihydroethidium combines with RNA or DNA to produce red fluorescence with a maximum excitation wavelength of 300 nm and a maximum emission wavelength of 610 nm. 535 nm can also be used as the excitation wavelength for actual observation.

CellTracker Blue CMAC is a non-fluorescent cell membrane permeable dye. The chloromethyl groups of CellTracker Blue CMAC are enzymatically cleaved by intracellular glutathione (GSH) to generate a fluorescent product (blue fluorescence, Ex/Em: 360/460 nm). CellTracker Blue CMAC is suitable for long-term cell tracking (up to 72 hours) and cell proliferation studies, and can also quantify GSH levels.

CellTracker Red CMTPX is a cell-permeable fluorescent dye that can be used as a cell tracer for monitoring cell movement and location (Ex/Em=586/614 nm).

CellTracker CM-DiI (CM-DiI) is a lipophilic fluorochrome that can be used for tracking the migration of lymphocytes. CellTracker CM-DiI is feasible to detect labeled cells in histological sections (excitation 553 nm; emission 570 nm).

5-Carboxyfluorescein diacetate N-succinimidyl ester is a cell permeable dye (Ex=492 nm, Em=517 nm). 5-Carboxyfluorescein diacetate N-succinimidyl ester can label cells by covalently binding to intracellular molecules. 5-Carboxyfluorescein diacetate N-succinimidyl ester is used to track lymphocyte migration and proliferation.

CellTracker Blue CMF2HC Dye is a blue dye, can be used in two-channel nuclei acid sequencing, with blue and purple excitation light (450-460 nm/400-405nm or 415-450 nm/480-525nm). CellTracker Blue CMF2HC Dye can be used to rapid determination of antibiotic sensitivity of microorganisms.

5-CFDA-AM is a cell-permeable esterase substrate that can be used as an active probe to measure enzyme activity and cell membrane integrity. 5-CFDA-AM is electroneutral and can enter the cell at a lower concentration than CFDA, where it is hydrolysed by intracellular esterases to produce carboxyfluorescein, which contains an additional negative charge and can be better retained in the cell. 5-CFDA-AM can be used to detect cell viability.

6-CFDA is a common aliphatic luciferin-line organism. CFDA conducts free diffusion into cells, and then it is hydrolyzed into carboxyl fluorescein (CF) by intracellular non-specific lipase. CF containing portion contains an additional negative charge so that it is better retained in cells, compared to fluorescein dyes.

7-Hydroxy-4-methylcoumarin-3-acetic acid is a growth inhibitor of root.

CellTracker Orange CMRA Dye is a fluorescent dye. CellTracker Orange CMRA Dye can be used for cell imaging and monitoring the movement and location of cells.

8RK59, a Bodipy probe, is a potent UCHL1 (ubiquitin C-terminal hydrolase L1) inhibitor, with an IC₅₀ close to 1 μM. 8RK59 could penetrate and label living cells. BodipyFL-alkyne is coupled to the azide of 8RK64 (HY-148254) using copper(I)-mediated click chemistry, resulting in compound 8RK59.

CytoRed (7-(Isobutyloxycarbonyloxy)-3H-phenoxazin-3-on) is a multifunctional dye. Dyes are important tools in biological experiments. They can help researchers observe and analyze cell structures, track biomolecules, evaluate cell functions, distinguish cell types, detect biomolecules, study tissue pathology and monitor microorganisms. Their applications range from basic scientific research to clinical A wide range of diagnostics. Dyes are also widely used in traditional fields such as textile dyeing, as well as in emerging fields such as functional textile processing, food pigments and dye-sensitized solar cells.

BODIPY TR methyl ester is a lipophilic GFP Counterstain. BODIPY TR methyl ester dye readily permeates cell membranes and localizes in endomembranous organelles but not localize strongly in plasma membranes. BODIPY TR methyl ester is an excellent red fluorescent vital dye (Ex=568 nm, Em=625 nm), can be used to reveal the location and shapes of cell nuclei, the shapes of cells within embryonic tissues, as well as the bound aries of organ-forming tissues within the whole embryo.

CytoTrace Red CMTPX is a cell permeable long-term cell tracer (Ex=577 nm, Em=602 nm).

7-Methoxycoumarin-3-carboxylic acid, SE can be used for the synthesis of hydrophilic dye compound 12. Compound 12 shows a homogeneous distribution inside the cell and represents a suitable probe for viscosity measurements in the cytoplasm.
