Abstract | Background. Immunolabeling of different microbial and viral antigens as well as antigens on eucaryotic cells is widely used today for diagnostic and research purposes in electron microscopy. Methods. We used colloidal gold method for detection of antigens in viral and bacterial suspensions and in infected cell cultures. Pre embedding and post embedding labeling techniques were employed. Results. Various bacterial and viral antigens were successfully labeled by using different immunogold techniques. Conclusions. Immunogold techniques are widely used today in electron microscopy laboratories for diagnostic and research purposes. We presented here a review of methods used in our laboratory. | |
Summary | Izhodišča. Imunsko označevanje različnih mikrobnih in virusnih antigenov kot tudi raznih antigenov v evkariontskih celicah uporabljamo pri diagnostiki povzročiteljev bolezni in pri raziskavah povezav med mikrobi in celicami. Metode Uporabili smo metode označevanja antigenov s koloidnim zlatom. Določali smo antigene pri virusih in bakterijah v suspenzijah kakor tudi v inficiranih celičnih kulturah, kjer smo jih označevali pred vklapljanjem v smolo (pre embedding labeling) in na ultratankih rezinah (post embedding labeling). Rezultati. Z uporabo ustreznih protiteles in koloidnega zlata smo z različnimi metodami označili iskane antigene. Zaključek. Metode označevanja s koloidnim zlatom so v elektronski mikroskopiji praktično nadomestile drugačne pristope označevanja antigenov, tako v diagnostične kot tudi v raziskovalne namene. V članku podajamo kratek pregled metod, ki jih uporabljamo v našem laboratoriju. | |
