1) Non-toxicity: The unique oiliness and high molecular weight characteristics of CelRed prevent it from penetrating cell membranes into cells. Ames test results also show that the mutagenicity of CelRed dye is much less than that of EB. 2) High sensitivi

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.

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.

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.

Cy5 maleimide (Cyanine5 maleimide) is a highly sensitive anatase dye for the detection of free thiols in natural protein extracts.

Nucleic Acid Dye Green I, a cell-impermeable fluorescent dye, is widely utilized for quantifying both dsDNA and ssDNA due to its excitation and emission peaks at 497 nm and 520 nm, respectively. Additionally, it finds applications in gene expression and RT-PCR assays.

2,6-Diiodo-BODIPY 493/503, a fluorescent F-Bodipy dye, features a diiodo substitution at the (pyrrole) 2,6 position. This pyrrole iodine substituent imparts a red hue to the compound [1].

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.

1) Non-toxicity: belong to flower-stem dye, easy to biodegrade, no carcinogenic toxicity. 2) High sensitivity: at least 100pg ssDNA or RNA can be detected, which is 25 ~ 100 times higher than EB staining. 3) High SIGNal-to-noise ratio: the sample fluorescence signal is strong, while the background signal is low. 4) Simple operation: like EB, the dye does not degrade in the prefabricated gel and electrophoresis process;The dyeing process after electrophoresis takes only 30 minutes without decoloring or washing, and can be observed directly with ultraviolet gel transmission or visible light transmission.
