Figure 1. Design and purification of Ab2/3H6Fab variants.

Figure 1

Three different Ab2/3H6Fab preparations were developed for the immunization study. Panel A. displays (a) the Fab-fragment HC of Ab2/3H6 named Ab2/3H6Fab. (b) human IL15 fused to Ab2/3H6Fab named Ab2/3H6Fab-IL15 and (c) a tetanus toxin epitope fused to Ab2/3H6Fab named Ab2/3H6Fab-TT. The chimeric mouse 3H6vL/hukappa LC (214 aa) is not shown. Panel B. shows the non-reduced SDS-gel of purified Fabs; silver stain (SS) on the left side and the Western Blot (WB) on the right side developed using an anti-human Fab specific antibody and visualized with NBT/BCIP. The lanes 1 represents Ab2/3H6Fab-TT (49 kD); lane 2: Ab2/3H6Fab-IL15 (61 kD); lane 3: Ab2/3H6Fab (47 kD) and M represents the marker. The double band is significant for glycosylated Ab2/3H6 [61].
