| 产品描述

Calcein Red-AM is a fluorogenic, cell-permeant fluorescent probe that indicates cellular health by detecting the activity of nonspecific esterases. When the acetoxymethyl ester is intact the probe is non-fluorescent, but when it is cleaved by nonspecific esterases present in healthy cells, the probe can be excited and emit at 560 nm/574 nm respectively. The signal of Calcein Red-AM is proportional to the cell vitality, as esterase activity decreases in cells with poor vitality. This cell-permeant probe is not retained with fixation and permeabilization.

1）Preparation

Zombie Violet™ Fixable Viability Kit is composed of lyophilized Zombie Violet™ dye and anhydrous DMSO. For reconstitution, bring the kit to room temperature; add 100 µl of DMSO to one vial of Zombie Violet™ dye until fully dissolved. 100 tests = 1 vial of Zombie Violet™ + DMSO, 500 tests = 5 vials of Zombie Violet™ + DMSO.

2）Storage & Handling

Store kit at -20°C upon receipt. Do not open vials until needed. Once the DMSO is added to the Zombie Violet™ dye, use immediately, or store at -20°C in a dry place and protected from light, preferably in a desiccator or in a container with desiccant for no more than one month.

3）Application

FC, ICFC - Quality tested；ICC - Verified

4）Recommended Usage

Each lot of this product is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometry, the suggested dilution is 1:100-1:1000 for 1-10 million cells. For immunocytochemistry, the suggested dilution is 1:1000. It is recommended that the reagent be titrated for optimal performance for each application, as optimal dosage varies with cell type.

5）Application Notes

Zombie Violet™ dye is excited by the Violet laser (405 nm) and has fluorescence emission maximum at 423 nm. If using in a multi-color panel design, filter optimization may be required depending on other fluorophores used. Zombie Violet™ dye has similar emission to Brilliant Violet 421™.
