Abstract

Przedmiotem zgłoszenia jest sposób wzbogacenia plazmy krwi drobiu w immunoglobulinę IgG polegający na wysalaniu białek, w roztworach NaCl, które następnie sedymentują w formie osadu w dolnej części zbiornika, a oddzielana jest część górna zasolonej plazmy ze zbiornika. Pozostała frakcja z osadem wysolonych białek zostaje rozrzedzona poprzez dodanie części wody, co powoduje rozpuszczenie IgG w wyniku obniżenia stężenia soli poniżej 6% wag. NaCl oraz zagęszczana techniką filtracji membranowej i odsalana poprzez dodawanie wody i kolejne zagęszczania (diafiltracja).
