Preparation of hEx3-scDb-Fcs with different domain orders. (A) Schematic diagrams of four types of hEx3-scDb-Fc. (B) Schematic diagrams of the expression vectors for hEx3-scDb-Fcs. (C) Gel filtration of hEx3-scDb-Fcs purified through protein A. AU, absorbance unit. (D) SDS-PAGE of each purification step in the preparation of hEx3-scDb-Fc-LH under reducing conditions (lane 1, 3) and non-reducing conditions (lane 2). Lanes 1, 2, after protein A purification; lane 3, peak fraction of gel filtration indicated by the arrow.
