Direct comparison of Abcam and competitor's Fura-2 AM. RAW 264.7 cells were loaded with 2 μM of Fura-2 AM from Abcam (ab120873) and competitor's in a DMSO/ HBSS solution for 30 minutes at room temperature and in the dark. After performing two washes with pre-warmed HBSS the cells were further incubated for 30 minutes at 37°C in the dark. Finally, washes with pre-warmed HBSS were performed and the live cells were imaged on a confocal microscope (using the same exposure settings) : excitation laser = 405nm, emission gate center = 519nm.
