Calcein Deep Red™

Calcein AM is one 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 GFP-tranfacted cells due to the same color to GFP. To address this color limitation of Calcein AM, we have developed Calcein Orange™, Calcein Red™ and Calcein Deep Red™. These new Calcein AM analogs enable the multicolor labeling and functional analysis of live cells in combination with Calcein AM. Calcein Deep Red™ is the esterase-hydrolyzed product of Calcein Deep Red™ acetate in cells. Calcein Deep Red™ dye can be monitored with the common Cy5 filter set. It is used as a fluorescence reference standard for Calcein Deep Red™ acetate.
