  • 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 week. 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.

Images

  • N-Formyl-Met-Leu-Phe activates Ca2+ transients in differentiated HL-60 cells.

    Cells were loaded with Fluo-3 AM (ab145254). Changes in intracellular Ca2+ were detected via changes in Fluo-3 emission following application (indicated by arrow) of 1 µM N-Formyl-Met-Leu-Phe (ab141806), (green) compared to control (black, saline perfusion).
