although estimates of the amount of pla2 in the melittin preparation suggested that such contamination was insufficient to explain at least some of the islet phospholipid hydrolysis and insulin release caused by melittin , we conclude that this agent does not serve as a specific probe of the role of endogenous pla2 or of aa lipoxygenation in hormone release .
