Presumptive insect circadian pacemakers in vitro: immunocytochemical characterization of cultured pigment-dispersing hormone-immunoreactive neurons of Leucophaea maderae.

abstract：:We used a combined biochemical and histocytochemical approach to study ecto-ATPase in the rat cardiac muscle. The reaction medium employed for histocytochemical detection was optimized in biochemical assays to achieve the highest enzyme activity and lowest inhibition by the capture agent used for visualization of the ...
