PI-3kinase reaction was set up ina total volume of50μlin a 1.5 ml microcentrifuge tube as described below.PI-3 kinase reaction buffer = 25 μlSpheroplast lysate = 20 μl (equivalent to 10 μg protein)Sonicated phosphatidyl inositol = 5 μlReaction mix was incubated at 25ºC for 20 min and enzyme reaction was stopped by adding 80μlHCL (1N) solution. To extract phospholipids, 160 μl chloroform:methanol (1:1) was added to the reaction mix withcontinuous mixing. Organic phase containing phopholipidswas separated fromaqueous phase by centrifugation at 7,500g for 4 min at 4ºC and transferred to a new vial. Using vacuum evaporator apparatus, solvent was evaporated and phospholipidsweredissolved in 10 μl chloroform
