Continuous fluorometric assay of Ca2+ transport by liposomes with Quin 2 entrapped: effect of phospholipase A2 and unsaturated long-chain fatty acids.

abstract：:Caffeine has been shown to enhance the lethal effect of DNA-damaging agents in mammalian cells, and the potentiation by caffeine of this effect is generally interpreted as the result of inhibition by caffeine of the repair of damaged DNA. However, the mechanism by which caffeine enhances the lethal effect of DNA-damag...
