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 .

N-Methylmesoporphyrin IX (NMM), a widely used G-quadruplex DNA specific fluorescent binder, is an efficient probe for monitoring Aβ fibrillation. N-Methylmesoporphyrin IX is an in situ inhibitor and an ex situ monitor for Aβ amyloidogenesis both in vitro and in cells. N-Methylmesoporphyrin IX is sensitive to G-quadruplexes DNA but has no response to duplexes, triplexes and single-stranded forms DNA. N-Methylmesoporphyrin IX is nonfluorescent alone or in monomeric Aβ environments, but emits strong fluorescence through stacking with the Aβ assemblies .

Chromomycin A3 is an inhibitor that selectively binds to GC-rich DNA sequences. Chromomycin A3 targets the DNA minor groove after forming a dimer with Mg 2+. Chromomycin A3 inhibits DNA replication and transcription, blocks the binding of Sp1 transcription factor to target gene promoters, downregulates the expression of anti-apoptotic proteins such as FLIP, Mcl-1, and XIAP, and induces S-phase cycle arrest and caspase-dependent apoptosis in tumor cells. Chromomycin A3 can antagonize oxidative stress induced by glutathione depletion and neuronal apoptosis induced by Camptothecin (HY-15660). Chromomycin A3 can be used in basic research on malignant tumors such as cholangiocarcinoma, and is a potential chemosensitizer and GC-rich region probe .

Biotin-11-dCTP is a biotinylated deoxynucleoside triphosphate and an important DNA labeling reagent. In random primer DNA labeling reactions, Biotin-11-dCTP incorporates into newly synthesized DNA strands to generate labeled DNA probes suitable for hybridization applications. In addition, Biotin-11-dCTP can serve as a substrate for terminal deoxynucleotidyl transferase to end-label oligonucleotides for telomere sequence detection, or to label the cut ends of linearized DNA molecules, thereby supporting streptavidin-based electron microscopy analysis. For example, Biotin-11-dCTP can label the cut ends of linearized DNA molecules under the action of dGTP and avian myeloblastosis virus reverse transcriptase .
