Nukleotydy adenylowe płytek krwi ssaków i trombocytów ptaków

In avian thtorabocytes, like in mammalian blood plateleta the adenine nucleotides are present in three distinguishable compartments. For studies of adenine nucleotide metabolic pool the turkey thrombocytes were prelabeled with 3 H-adenine. The level of metabolic nucleotides' was follewed by measuring their total radioactivity. Part of the metabolic adenine nucleotide pool was not gextracted by 50% ethanol. This ethanol-insoluble fraction (about 5 nmol/10 thrombocytes) represents adenine nucleotides bound to F-actin.
