  • Serum pretreatment in digoxin immunoassay
    Patent number: 4798804
    Abstract: A method is disclosed for preparing a sample suspected of containing digoxin for determination of digoxin in the sample during an assay. The method comprises contacting the sample with .beta.-cyclodextrin in an amount and under conditions sufficient to allow a substantial portion of digoxin in the sample to bind to the .beta.-cyclodextrin. The .beta.-cyclodextrin with bound digoxin is separated from at least one other component of the medium. Next, the digoxin is released from the .beta.-cyclodextrin to provide a sample containing digoxin which may be analyzed by any of a number of assay techniques.
