Abstract

Predlozeni izum spada v podrocje farmacevtske industrije in se nanasa na novamonoklonska protitelesa in njihove fragmente, ki se vezejo na dostopno povrsino humanega rekombinantnega TNF-Alfa, TNF-Alfa analogov in TNF-Alfa topnih receptorjev. Izum se nanasa se na stabilne celicne linije hibridomov, ki so sposobne taka monoklonska protitelesa proizvajati, postopek za njihovo pripravo in farmacevtske pripravke, ki jih vsebujejo. Nadalje se izum nanasa tudi na metodo za kvantitativno dolocanje humanega TNF-Alfa, prostega in kompleksnega s topnima TNF-Alfa receptorjema p55 in p75 ter kit, ki se pri tem uporablja. Z do sedaj poznanimi monokonskimi protitelesi in iz njih razvitimi reagenti ni bilo mozno istocasno dolocati tako prostih makromolekul TNF-Alfa in njihovih topnih receptorjev kot tudi njihovih kompleksov. Predmet tega izuma je tudi TNF-Alfa analog TNF-Alfa His107/108, Cys95/148, ki ga v kompleksu s TNF-Alfa receptorjema uporabljamo kot antigen za imunizacijo misi.
