Rhod-2 AM
Based on 42 publication(s) in Google Scholar
Rhod-2 is a high-affinity visible light excitation wavelength Ca2+ fluorescent probe, Rhod-2, AM is an acetyl methyl ester derivative of Rhod-2, which has cell membrane permeability and can easily enter cells with simple culture. Once it enters the cell, it is sheared by its lactesterase to produce Rhod-2 without membrane permeability, which remains in the cell to perform the corresponding physiological functions. Maximum excitation/emission wavelength: 549/578 nm.

For flow cytofluorometry, cells are harvested, pelleted, and resuspended in ice-cold PBS containing 10 mM glucose, 10% fetal bovine serum (FBS), and 10 μM Rhod-2 AM (Rhod2-AM). Mitochondrial calcium levels are determined by the flow cytofluorometry analysis of aliquots of 4×105 cells. For fluorescence microscopy, IMR5 cells are grown on polylysine-coated (10 μg/mL) slides and stained with 7.5 μM Rhod-2 AM in Dulbecco's modified Eagle's medium (DMEM) supplemented with 10% FBS for 2 h before poliovirus (PV) infection. Cells are fixed by incubation for 15 min at 4°C in 4% paraformaldehyde. Cells are washed in PBS, and images are acquired with Zeiss Apotome and Axiovision software[1].
