Calcein Red(TM) AM

Ex: 560 nm. Em: 574 nm. Soluble in: DMSO. Calcein AM is one of the most popular fluorescent probes used for labeling and monitoring cellular functions of live cells. However, the single color of Calcein AM makes it impossible to use this valuable reagent in the multicolor applications. For example, it is impossible to use Calcein AM in combination of GFP-tranfacted cells due to the same color to GFP. To address this color limitation of Calcein AM, we have developed Calcein Orange(TM), Calcein Red(TM) and Calcein Red(TM). These new Calcein AM analogs enable the multicolor labeling and functional analysis of live cells in combination with Calcein AM. Non-fluorescent Calcein Red(TM) AM can easily get into live cells and hydrolyzes to generate strongly fluorescent Calcein Red(TM) dye. Calcein Red(TM) dye can be monitored with the common TRITC/Cy3 filter set. AAT Bioquest offers Calcein Red(TM) as a reference dye to Calcein Red(TM) AM.
