Alle primære antistoffer
Primære antistoffer, immunoglobuliner, der binder til specifikke proteiner eller andre biomolekyler, bruges i mange forskningsapplikationer og protokoller til at påvise mål af interesse. De er udviklet ved hjælp af forskellige dyreværter, herunder mus, rotte, kanin, ged, får og mange andre.
Monoklonale
og polyklonale antistoffer En type primære antistoffer, monoklonale antistoffer, giver høj reproducerbarhed og lav krydsreaktivitet og baggrundsstøj. En anden type, polyklonale antistoffer, koster ofte mindre og giver større affinitet og hurtigere binding. Begge er produceret ved hjælp af plasma B-celler, men førstnævnte bruger den samme klon, og sidstnævnte bruger forskellige kloner. Monoklonale antistoffer kræver hybridomcellelinjer, og polyklonale antistoffer gør det ikke.
Der er også rekombinante monoklonale antistoffer med lignende fordele, såsom høj affinitet, skalerbarhed og specificitet. De er produceret vha in vitro kloning af plasma B-celler og ekspressionsværter.
Konjugerede primære
antistoffer Antistoffer kan mærkes med forskellige fluoroforer eller detektionsmidler eller anvendes uden mærker. Mærkede primære antistoffer, også kendt som konjugerede primære antistoffer, hjælper forskere med at forenkle og strømline deres applikationer. De er koblet med almindelige enzymer og farvestoffer såsom Alexa Fluor og bruges ofte i protein- og celleanalyse.
Anvendelser Antistoffer til biovidenskabsapplikationer bruges i flowcytometri, western blotting, ELISA, immunhistokemi og immuncytokemi. Sekundære antistoffer kan tilsættes for at understøtte påvisning og oprensning af visse antigener. De binder til det primære antistof, som binder til antigenet af interesse. At finde den rigtige kombination af antistoffer kan resultere i større antigenspecificitet og et stærkt, detekterbart signal.
