Claims (15)

1. Heteromultimer, der omfatter: mindst et første monomert protein, som omfatter (i) et første transporterpolypeptid, der omfatter et første segment af serumalbumin og (ii) mindst ét lastpolypeptid, og mindst et andet monomert protein, som omfatter (iii) et andet transporterpolypeptid, der omfatter et andet segment af serumalbumin og (iv) mindst ét lastpolypeptid; hvor det første transporterpolypeptid er forskelligt fra det andet transporterpolypeptid, og hvor transporterpolypeptiderne er selv-samlende til dannelse af en kvasi-nativ struktur af serumalbumin.
2. Heteromultimer ifølge krav 1, hvor heteromultimeren er en heterodimer.
3. Heteromultimer ifølge krav 1 eller 2, hvor transporterpolypeptiderne er afledt af humant serumalbumin med en sekvens ifølge SEQ ID NO: 1, og mere fortrinsvis hvor det første transporterpolypeptid har en sekvens, der omfatter SEQ ID NO: 2, og det andet transporterpolypeptid har en sekvens, der omfatter SEQ ID NO: 3, eller hvor det første transporterpolypeptid har en sekvens, der omfatter SEQ ID NO: 8, og det andet transporterpolypeptid har en sekvens, der omfatter SEQ ID NO: 10.
