DNA dyes

DAPI Dihydrochloride (FxCycle Violet) is A cell-permeable fluorescent probe. By binding to small forests rich in A-T DNA sequences, it is used to stain DNA and chromosomes, with a preference for DNA rich in adenine and thymine.

Hoechst 33342 (bisBenzimide H 33342) is a benzimidazole fluorescent dye and a cell-permeable fluorescent DNA dye.

Biotin-aniline is a probe that reacts strongly to RNA and DNA.Biotin-aniline is highly efficient and is used to capture subcellular transcriptomes in living cells with high spatial specificity.

5-ROX, SE ([5-Carboxy-X-rhodamine, succinimidyl ester] *Single isomer*) is a labeling reagen used in the preparation of charge-modified dye-labeled Dideoxynucleotide Triphosphates (ddNTP) to "direct-load" DNA sequencing.

Thiazole Orange is a dye that can be used for reticulocyte analysis.

Ethidium bromide (EB) A trypanocidal agent and possible antiviral agent that is widely used in experimental cell biology and biochemistry. Ethidium has several experimentally useful properties including binding to nucleic acids, noncompetitive inhibition of nicotinic acetylcholine receptors, and fluorescence among others. It is most commonly used as the bromide. Ethidium bromide has a λEx of 300-360 nm and a λEm of 590 nm.

Hoechst 33258 trihydrochloride (Bisbenzimide) is a benzimidazole anti-filarial agent. it is fluorescent when it binds to certain nucleotides in DNA, thus providing a tool for the study of DNA replication. it also interferes with mitosis.

6-Carboxyfluorescein (6-FAM) contains a carboxylic acid functional group, facilitating reactions with primary amines through carbodiimide activation.

Hoechst 34580 xHCl(23555-00-2(free base) is a cell-permeable fluorescent dye, is used for staining DNA and nuclei.

2-Aminopurine is a double-stranded RNA-dependent protein kinase, protein kinase R (PKR) inhibitor.

HOE 32021 is an intracellular DNA dye that binds to nucleic acids by intercalating in the minor groove of DNA duplexes.

3,6-Dichlorotrimellitic acid serves as the fundamental precursor for the synthesis of numerous dichlorinated fluoresceins and rhodamines.

Hoechst 33258 analog 3 is part of a family of blue fluorescent dyes used to stain DNA.

3,6-Dichlorotrimellitic anhydride serves as the essential precursor in the synthesis of various dichlorinated fluoresceins and rhodamines.

SYBR Green Ⅰ (Green-DNA Dye, SYBR Green I) is a dye that binds to all dsDNA double helix minor groove regions, with a maximum absorption wavelength around 497nm and a maximum emission wavelength around 520nm.

CelGreen nucleic acid gel stain *10,000× concentrate in water* is a fluorescent dye with a unique involvement that binds to all dsDNA double helix sulcus regions.In the free state, the side strand and CelGreen emit weak fluorescence, but the fluorescence is greatly enhanced once they are combined with the double-stranded DNA. Therefore, the fluorescence signal strength of CelGreen is related to the amount of double-stranded DNA, and the amount of double-stranded DNA in the PCR system can be detected according to the fluorescence signal.

Cy5.5 diacid is commonly used in biomolecular labeling, fluorescence imaging and other fluorescence biological analysis. Cy5.5 dyes and their derivatives are widely used to label polypeptides, proteins and nucleic acids.

CelGreen nucleic acid gel stain *10,000× concentrate in DMSO* is a fluorescent dye with a unique involvement that binds to all dsDNA double helix sulcus regions.In the free state, the side strand and CelGreen emit weak fluorescence, but the fluorescence is greatly enhanced once they are combined with the double-stranded DNA. Therefore, the fluorescence signal strength of CelGreen is related to the amount of double-stranded DNA, and the amount of double-stranded DNA in the PCR system can be detected according to the fluorescence signal.

Pyrene Phosphoramidite Du, a click chemistry reagent featuring pyrene moieties, can be incorporated into DNA, resulting in pronounced blue fluorescence.

Hoechst 33258 analog 6 is an analog of Hoechst stains which are part of a family of blue fluorescent dyes used to stain DNA.

7-Methoxycoumarin-3-carboxylic acid may be used as a reference compound in the purification, separation and analysis of coumarin compounds.

Setoglaucine is a basic dye used to stain DNA.

ATBTA-Eu3+ is a fluorescent europium chelate useful for DNA labeling [1].

1-Pyrenebutyric acid is a useful organic compound for research related to life sciences. The catalog number is T64993 and the CAS number is 3443-45-6.
