Application

The succinimidyl ester group is capable of spontaneously and irreversibly binding to free amines. Utilized in flow cytometry experiments for tracking cell division in both mammalian cells and bacteria. Used in combination with several cell permeabilizers as an effective, nondestructive fluorescencent stain to quickly detect bacterial cells.

Other Notes

Reagent for continuously determining the intracellular pH in bacteria by fluorometry; labeling human intervertebral disk cells in vitro for fluorescence microscopy
