Figure 1 - HepG2 or HeLa cells were grown to 80% confluency and then serum starved overnight. HepG2 Cells were treated with IGF for 10 minutes. HeLa Cells were treated with Calyculin A for 30 minutes. Data shown are from a 20 second exposure using a chemiluminescence imaging system.

For best results, store the entire kit frozen at -20°C upon arrival. Stored frozen, the kit will be stable for at least 6 months which is the duration of the product warranty period. Once thawed, store array membranes and 1X Blocking Buffer at -20°C and all other reagents undiluted at 4°C for no more than 3 months.
