Handling
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.

Functional Studies - Fluo-8 AM, green fluorescent calcium binding dye (ab142773) Cui et al PLoS One. 2013;8(3):e59921. doi: 10.1371/journal.pone.0059921. Epub 2013 Mar 20. Reproduced under the Creative Commons license http://creativecommons.org/licenses/by/4.0/
FFA treatments increase Ca2+ influx to induce ERS in β-TC3 cells.
β-TC3 cells were incubated with FFA or BSA for 16 h, and then stimulated with 4 µM thapsigargin for 20 min to activate store-operated Ca2+ entry. Fluorescence densities of Ca2+ change were monitored in Fluo-8/AM-loaded β-TC3 cells after FFA or BSA treatments.

Fluorescent Cell Imaging - Fluo-8 AM, green fluorescent calcium binding dye (ab142773)U2OS cells were seeded overnight at 40,000 cells per 100 µL per well in a 96-well black wall/clear bottom costar plate. The growth medium was removed, and the cells were incubated with 100 µl of 4 µM Fluo-4 AM or Fluo-8® AM in HHBS at 37 °C, 5% CO2 incubator for 1 hour. The cells were washed twice with 200 µl HHBS, then imaged with a fluorescence microscope using FITC channel.
