title: Synthesis and characterisation of an iodinated bile-salt derivative for photoaffinity labelling.
abstract: The synthesis and characterisation of a novel iodinated bile salt derivative, 125I-labelled 3 beta-azidocholylhistamine, is described. The derivative is handled by rat liver in a similar manner to taurocholate and binding to bovine serum albumin, a well-characterised bile acid-binding protein, is demonstrated. The suitability of the derivative for photoaffinity labelling is assessed.
