Biological Activity

Fluorescent endoplasmic reticulum and plasma membrane stain. Exhibits rapid uptake in live cells. Displays low cytotoxicity and is resistant to photobleaching. Suitable for imaging live and fixed cells in short and long time course experiments. Compatible with fluorescent microscopy using single photon excitation at 403 nm or two-photon excitation between 800 and 830 nm. Excitation/emission λ: 350-405 nm / 500-650 nm.

Application of ReZolve-ER™ on PNT2 prostate epithelial cells

PNT2 prostate epithelial cell line stained with ReZolve-ER™  PNT2 prostate epithelial cell line stained with ReZolve-ER™ (green) and CellMask (purple)*

Left: PNT2 prostate epithelial cells stained with ReZolve-ER™. Right: PNT2 prostate epithelial cells stained with ReZolve-ER™ (green) and CellMask (purple)*.

Cells are incubated with growth media containing 20 μM ReZolve-ER™ for 10-20 min before imaging. Cells were viewed using a Nikon+A1 confocal microscope, ReZolve-ER™ is excited at 403 nm and emission is collected using a 525 nm GaaS PMT detect.

*CellMask was purchased from Thermo Fisher
