Figure 6. Comparison to DS-Cav1.
(a) Protein expression levels for double mutant single chain (SC-DM) and triple mutant single chain (SC-TM) were compared with DS-Cav1 (ref. 10) in cell culture supernatants 72 h post transfection and (b) the fraction of RSV F protein binding to prefusion-specific CR9501 antibody after storage at 4 °C for indicated days. Bars or symbols represent average from two measurements, lines represent range of values. On (b) prefusion F fraction at day of harvest (day 0) is normalized to 1.
