WST-1 (solution) is a kind of water-soluble tetrazolium salt. WST induces the intracellular mitochondrial dehydrogenase to conduct NADH-dependent enzyme digestion reaction, releasing the water-soluble methyl benzene product. WST-1 can be used for the detection of cell proliferation and cytotoxicity, via the determination of the light absorption value at 450 nm.

FITC-Dextran (MW 4000) (solution) is a fluorescent probe for fluorescein isothiocyanate (FITC) dextran (Ex=495 nm; Em=525 nm). FITC-Dextran (MW 4000) can be used as a marker to reveal heat shock-induced cell damage and to study the early and late stages of apoptosis. FITC-Dextran (MW 4000) can also be used for cell permeability studies, such as blood-brain barrier permeability and determination of the extent of blood-brain barrier disruption.

FITC-Dextran (MW 70000) (solution) is a compound belonging to the class of fluorescent dyes. It is commonly used in biomedical research as a tracer molecule to label and track cells or other biological matter. FITC-Dextran consists of fluorescein isothiocyanate (FITC) and dextran, a complex carbohydrate derived from starch. The combination of the two creates a stable fluorescent tracer that can be viewed under a microscope or quantified using specialized detection instruments.
Solvent and concentration: ddH2O: 1 mM

Thiazolyl Blue (solution) (MTT (solution)) is a cell-permeable and positively charged tetrazolium dye that is used to detect reductive metabolism in cells. Thiazolyl Blue is taken up by cells through the plasma membrane and then reduced to formazan by intracellular NAD (P) H-oxidoreductases. Thiazolyl Blue is frequently used in colorimetric assays to measure cell proliferation, cytotoxicity, and apoptosis.
Solvent and concentration: PBS: 5 mg/mL

BCECF (solution) (2′,7′-Bis(2-carboxyethyl)-5(6)-carboxyfluorescein (solution)) is a cell-impermeant pH-sensitive fluorescent dye. BCECF allows measurements in the physiological pH range 6.0-8.0. Excitation ratio: 490/440 nm; Emission intensity: 535 nm.
Solvent and concentration: DMSO: 10 mM

TPE-MI (Tetraphenylethene maleimide) (solution) is a thiol probe for measuring unfolded protein load and proteostasis in cells (the excitation wavelength is 350 nm and the emission wavelength is 470 nm). TPE-MI can report imbalances in proteostasis in induced pluripotent stem cell models of Huntington disease, as well as cells transfected with mutant Huntington exon 1 before the formation of visible aggregates. TPE-MI also detects protein damage following dihydroartemisinin research of the malaria parasitesPlasmodium falciparum .
Solvent and concentration: DMSO: 10 mM

2′,7′-Dichlorofluorescein diacetate (DCFH2-DA) (solution) is a cell-permeable fluorescent probe. 2′,7′-Dichlorofluorescein diacetate can be used to detect the generation of reactive oxygen intermediates and for assessing the overall oxidative stress in toxicological phenomenon.
Solvent and concentration: DMSO: 10 mM
The 1 mL volume is defined as the base specification. All larger sizes correspond to incremental volumes of this base.

1,3-Diphenylisobenzofuran (DPBF) (solution) has been developed as a selective probe for the detection and quantitative determination of hydrogen peroxide in samples containing different reactive nitrogen and oxygen species (RNOS). DPBF is a fluorescent probe which, for almost 20 years, was believed to react in a highly specific manner toward some reactive oxygen species such as singlet oxygen and hydroxy, alkyloxy or alkylperoxy radicals.
Solvent and concentration: DMSO: 10 mM
The 1 mL volume is defined as the base specification. All larger sizes correspond to incremental volumes of this base.

Resazurin sodium (Diazoresorcinol sodium) (solution) is a non-toxic, stable, membrane-permeable blue non-fluorescent dye (faintly fluorescent). Resazurin sodium is used as a redox indicator, can be reduced to pink, highly fluorescent Resorufin (Ex=530-560 nm, Em=590 nm) in living cells. Resazurin sodium can be used for the detection of cell viability, toxicity, proliferation, migration and invasion in cells (human, plant and animal, bacterial and fungal) .

Suc-Leu-Leu-Val-Tyr-AMC (solution) is a membrane-permeable calpain-specific fluorogenic substrate (Ex/Em = 390/480 nm) .
Solvent and concentration: DMSO: 20 mM

Monochlorobimane (Chlorobimane) (solution) is a fluorescent dye (λ_ex=380 nm, λ_em=470 nm) to measure glutathione (GSH) in cellular assays.
Solvent and concentration: DMSO: 10 mM

Nicotinamide 1,N6-ethenoadenine dinucleotide (solution) (ε-NAD (solution)) is a fluorescent analog of NAD. Nicotinamide 1,N6-ethenoadenine dinucleotide can be cleaved by phosphodiesterase I (from C. adamanteus venom) and binds to bovine liver glutamate dehydrogenase. Nicotinamide 1,N6-ethenoadenine dinucleotide can serve as a substrate for G-ADP ribosylation of G proteins catalyzed by bacterial toxins. Nicotinamide 1,N6-ethenoadenine dinucleotide can be used as a fluorescent substrate for the study of ADP ribosylation reactions.
