AT-dye is a common fluorescent dye. It can be used as a fluorescent label and molecular probe for a series of biomolecules such as proteins and nucleic acids. Its spectrum covers the range from ultraviolet light to near-infrared light, and it is the most complete fluorescent label. Compared with other dyes, it has excellent light stability and brightness in the red spectral region.

AT-dye is an emerging fluorescent dye in recent years. Its fluorescent labeling band is the most complete, and it can label some biological macromolecules that cannot be labelled by fluorescent dyes. Xi'an Confluore has a series of AT-dye dyes to choose from, including : AT 390 Acid，AT 425 Acid，AT 465 Acid，AT 488 Acid，AT 495 Acid，AT 514 Acid，AT 520 Acid，AT 532 Acid，AT 565 Acid，AT 590 Acid，AT 610 Acid，AT 647 Acid and other dyes .
