title: [Preparation of an anti-idiotypic antibody directed against anti-dexamethasone antibody and demonstration of its ability to acknowledge the receptor of glucocorticoids].
abstract: By using a 3-carboxymethyloxime dexamethasone derivative coupled to bovine serum albumin we have prepared specific anti-dexamethasone antibodies in rabbits. These antibodies were then purified by affinity chromatography and administered to a second set of rabbits. One of them produced anti-idiotypic antibodies able to impede the [3H] dexamethasone binding of the initial anti-dexamethasone antibodies and to displace the [3H] dexamethasone-antibodies complexes towards high molecular weight species in gel filtration experiments. Moreover these antibodies we were also able to impede the binding of [3H] dexamethasone to the rat liver glucocorticoid receptor and to recognize the highly purified receptor using Western blot analysis.
