| 产品描述

CFSE Cell Division Tracker Kit is composed of 5 vials, 100 µg per vial of CFSE (formally known as 5-(and 6)-Carboxyfluorescein diacetate succinimidyl ester of CFDA SE), and 500 µl of anhydrous DMSO. CFSE is able to passively diffuse into cells. Inside the cell, its acetate groups are cleaved by intracellular esterases, and the molecules are converted to fluorescent esters. CFSE is retained within the cell and covalently couples to intracellular molecules via its succinimidyl group. Due to this covalent coupling reaction, fluorescent CFSE can be retained within the cell for an extremely long period. Also, due to this stable linkage, once the dye has been incorporated within the cell, it is not transferred to adjacent cells. CFSE is widely used for cell proliferation assays and in vivo cell tracking.

1）Preparation

The CFSE Cell Division Tracker Kit is composed of lyophilized CFSE and anhydrous DMSO. For reconstitution, bring the kit to room temperature; add 36 µl of DMSO to one vial of CFSE dye until fully dissolved.

2）Storage & Handling

Store CFSE Cell Division Tracker Kit at -20°C upon receipt. Do not open vials until needed. Once the DMSO is added to the CFSE, use immediately, or store at -20°C in a dry place and protected from light, preferably in a dessicator or in a container with desiccant for no more than one month.

3）Application

ICFC - Quality tested；In vivo cell tracking1 - Reported in the literature, not verified in house

4）Recommended Usage

This lot has been tested by flow cytometric analysis of in vitro cell proliferation assay. It can be used at concentrations ranging from 0.5 - 10 µM for cell labeling. It is recommended that the reagent be titrated for optimal performance for each cell type, culturing condition, or application.

5）Application Notes

The molecular weight of CFSE is 557.47. The excitation and emission wavelengths of CFSE-labeled cells are 492 nm and 517 nm, respectively. Each 100 µg vial of CFSE may be reconstituted with 36 µl of anhydrous DMSO to yield a stock concentration of 5 mM.
