Acridine is a small cationic and planar dye that mainly binds to RNA and DNA. These dyes are strongly fluorescent. It resembles the structure of xanthene except that the heteroatom is nitrogen, not oxygen. Acridine is suitable for nucleic acid staining, particularly for cell cycle determination. Acridines are used as fluorescent materials for visualisation of biomolecules, and in laser technologies.

Poly-L-lysine is a positively charged amino acid polymer with approximately one HBr per lysine residue. The hydrobromide allows the poly-L-lysine to be in a crystalline form soluble in water. A small amount of product may be found in the beta structure because the HBr interferes with hydrogen bonding between amino and either the carboxyl groups or N or O containing moieties.

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.
