Abstract

A new radioimmunoassay which allows the measurement of the rat vasoactive intestinal polypeptide, was performed. VIP is present in the whole digestive tract of rat, mainly between the duodenum and the colon. 1.5% of the total VIP is present in brain. The VIP-like immunoreactivity appears to correspond to biologically active molecule since a radioreceptorassay using liver plasma membranes as the target tissue, gives the same results as the radioimmunoassay.
