处理
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

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.

Direct comparison of Abcam and competitor’s Fura-2 AM. RAW 264.7 cells were loaded with different concentrations 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.
