Framstälining au protein-steroid konjugat och antisera mot 17β-estradiol
Acta Veterinaria Scandinavica volume 14, pages 278–291 (1973)
Abstract
A conjugate of oestradiol-17β and bovine serum albumin (BSA) has been prepared by the mixed anhydride method. The conjugate was characterized by u.v.-analyses and immunoelectrophoresis, and the number of moles of oestradiol-17β per mole of BSA was found to be 25. The conjugate was used for immunization of two sheep and one rabbit in order to elict antisera against oestradiol-17β. Antibodies could be detected in all three animals after 5–16 weeks depending on the route of immunization. The antiserum from one sheep could be used in a radioimmunoassay system for oestradiol-17β in a dilution of 1:5000 and was found to cross-react with oestrone and oestradiol-17α to a lesser extent than another antiserum against oestradiol-17β.
Sammanfattning
Ett konjugat av 17β-estradiol och bovint serum albumin (BSA) har framställts med „mixed anhydride“ metoden. Konjugatet karaktariserades med u.v.-analys och immunoelektrofores och antalet mol av 17β-estradiol per mol BSA beräknades till 25. Konjugatet användes for immunisering av två får och en kanin for att framställa antisera mot 17β-estradiol. Antikroppar kunde pävisas hos alla tre djuren efter 5–16 veckor. Antiserum från ett får kunde användas i ett radioimmunologiskt system för 17β-estradiol i en spädning 1:5000 och korsreagerande med estrone och 17α-estradiol i mindre utsträckning i jämförelse med ett annat antiserum mot 17β-estradiol.
