Popis: The ficoll density gradient method, the most widely used method for isolating avian peripheral blood mononuclear cells (PBMCs), results in significant contamination with nucleated thrombocytes. This thrombocyte contamination can affect both immunophenotyping and functional assays of T cells. We used full blood samples from ten vaccinated male layer hybrid chickens for isolating PBMCs, and have developed a low cost, combined dextran and ficoll density gradient separation method which, in comparison to the standard ficoll density gradient separation, markedly reduces thrombocyte contamination of the isolated PBMCs. An ex vivo T cell proliferation assay showed an overall reduced background proliferation in unstimulated and stimulated samples after combined dextran and ficoll separation of PBMCs, resulting in a statistically significant difference upon in vitro NDV challenge
Metoda razdvajanja gradijentom gustoće pomoću fikola najčešće je korištena metoda za izdvajanje leukocita iz periferne krvi ptica, ali koja rezultira značajnom kontaminacijom trombocitima. Trombociti u populaciji izdvojenih stanica utječu na rezultate fenotipskih (imunofenotipizacija), ali i funkcionalnih testova T limfocita. Koristeći uzorke pune krvi od 10 cijepljenih muških pilića komercijalnog hibrida nesilica razvili smo metodu izdvajanja leukocita kombiniranom primjenom dekstrana i gradijenta gustoće pomoću fikola CD8αex vivo test proliferacije T limfocita pokazao je smanjenu pozadinsku proliferaciju nestimuliranih stanica nakon izdvajanja leukocita kombiniranom primjenom dekstrana i fikola.
