1-Methoxy-5-methylphenazinium methyl sulphate ≥95%, Sigma-Aldrich®

Supplier: SIGMA ALDRICH MICROSCOPY

1-Methoxy-5-methylphenazinium methyl sulfate (MPMS) is a photochemically stable electron-transport mediator between NAD(P)H and tetrazolium dyes. The reduced form of MPMS converts tetrazolium salt to purple precipitate formazan. It is a very stable and non-enzymic electron carrier that mediates electron transfer by dehydrogenases in vitro to various electron acceptors such as tetrazolium dyes or the electrode of an enzymic electric cell.

Phloroglucinol, Sigma-Aldrich®

Supplier: SIGMA ALDRICH MICROSCOPY

Phloroglucinol (phlo) is a phenol derivative that shows a cytoprotective effect from oxidative damage by enhancing the activity of cellular catalase. It can also be used to prepare synthetic analogs of A-type proanthocyanidins (PACs) such as 2,8-dioxabicyclo nonane derivatives by reacting with the corresponding flavylium salts. Phlo can react with benzaldehyde derivatives to form phloroglucinol-based microporous polymeric organic frameworks (phlo-POF) with potential applications in ion exchange and gas adsorption. Phloroglucinol is an antispasmodic and a derivative of phenol.

5-Fluorouracil ≥99% (by HPLC), powder, Sigma-Aldrich®

Supplier: SIGMA ALDRICH MICROSCOPY

5-Fluorouracil has been used to induce apoptosis in cells. It has been used as a chemosensitising agent. A potent antitumor agent that affects pyrimidine synthesis by inhibiting thymidylate synthetase, thus depleting intracellular dTTP pools. It is metabolized to ribonucleotides and deoxyribonucleotides, which can be incorporated into RNA and DNA. Treatment of cells with 5-FU leads to an accumulation of cells in S-phase and has been shown to induce p53 dependent apoptosis.

Wright's stain used as a blood stain, Sigma-Aldrich®

Supplier: SIGMA ALDRICH MICROSCOPY

Wright′s Stain solution is commercially available and is generally used in hematology. Its preparation involves heating methylene blue with sodium bicarbonate and combining the mixture with eosin. It is alkaline, hence, its concentration is continuously changing due to the progressive oxidizing action of the alkali. Therefore, Giemsa′s stain is added to preserve the azurophilic properties of polychrome dyes.

Tetrabromophenol blue, Sigma-Aldrich®

Supplier: SIGMA ALDRICH MICROSCOPY

Tetrabromophenol Blue (TBPB) belongs to the group of sulfonephthalein acid-base indicators. It is employed in the potentiometric titration of the halogens with Hg₂(NO₃)₂. In addition, it has been used as a dye indicator in urine dipstick test to detect proteinuria. In this assay, with increasing concentration of urinary protein, TBPB sequentially changes colour from pale green to blue. Binding of TBPB to proteins is dependent on pH.
