A radioimmunoassay for arginine-vasotocin (AVT), the antidiuretic principle in birds, was developed using the high cross-reactivity of AVT with an AVP antiserum raised in rabbits. This assay is specific for the measurement of AVT in serum of birds. The sensitivity and precision is such that serum AVT concentrations above 0.5 fmol/ml can be measured quantitatively. A serum AVT concentration of 5.1±1.4 fmol/ml was found in normally hydrated, fresh water adapted ducks with a serum osmolality of… CONTINUE READING
