Study Type In Vitro
Model 2450 MHz (AM 50 Hz)exposure to isolated protein and evaluation of conformational and activity changes
Details

Porcine heart protein citrate synthase (which unfolds and binds strongly to the chaperone alpha crystallin when exposed to increased temperature) in solution was exposed to 2450 MHz RF for 10, 15, or 20 seconds in a conventional microwave oven at a reported SAR of 4.85 kW/kg. Temperature rise was determined with a luxtron probe positioned near the bottom of the tube. The amount of unfolded CS was determined by affinity capture on an alpha crystallin substrate. The authors report heating by microwave resulted in higher CS unfolding and different kinetics than conventional heating in a water bath. The authors do not think the result is an effect of hot spots, and suggest it is a non-thermal contribution of microwave energy.
