  • Saturation analysis of folate compound with selenium-75 labeled folate
    Patent number: 4115065
    Abstract: Folic acid and related compounds are assayed by competitive radio-assay using a selenium - 75 labelled version of folic acid as the competing compound.
    Type: Grant
    Filed: December 11, 1974
    Date of Patent: September 19, 1978
    Assignee: The Radiochemical Centre Limited
    Inventors: Russell James Bayly, Virginia Edith May Chambers, Reginald Monks
  • Saturation analysis
    Patent number: 4030886
    Abstract: The invention provides a method and a kit for the saturation analysis of a steroid characterized by the use of a selenium-75 labelled version of the steroid to be assayed. Selenium-75 derivatives of steroids are quite simple to prepare and have practical advantages over other radioactively labelled steroids. Lists of derivatives and examples of competitive radio-assays are given.
    Type: Grant
    Filed: December 5, 1974
    Date of Patent: June 21, 1977
    Assignee: The Radiochemical Centre Limited
    Inventors: Russell James Bayly, Virginia Edith May Chambers, Reginald Monks
  • Selenium-75 steroids
    Patent number: 3952030
    Abstract: Novel dimeric and monomeric selenium-75 derivatives of steroids are made by reacting a keto steroid with selenium-75 dioxide or selenious acid-Se75. The resulting diselenide dimers can be converted into monomeric compounds by the use of a cleaving reagent followed by an alkylating agent. The compounds are useful in saturation analyses such as radioimmunoassays.
