The modulation of enzyme activity by the scFv would support the notion of an active site accessible to large molecules.
The modulation of enzyme activity by the purified scFvs reflected that the selection strategy was targeted towards the active site of PLAP.
This strategy has enabled us to isolate a high proportion of scFv antibodies that are isozyme specific and bind to the active site, as evidenced by the modulation of enzyme activity.
Yeast surface display experiments indicate that comparable levels of scFv and scFv-Fc can be displayed on the yeast surface, while binding experiments indicate that scFvs are better binders then their scFv-Fc counterparts.
Construct output, capacity and growth rate of scFv constructs with alternative optimized sequences.
At scFv densities greater than 148 scFv/IL, there was no effect of scFv affinity on IL binding and uptake into tumor cells, or on cytotoxicity.
In this context, ELISA measured the immunoreactivity of scFv.
In this study, however production of scFv increased as temperature elevated, suggesting that the proteases did not seriously affect scFv production in the conditions tested.
Humanisation of scFv was performed by grafting the CDRs of the VL and VH domains into a human scFv framework leading to the single chain antibody 22C4 scFv.
Thus, barnase moiety of scFv 4D5-dibarnase retained its functionality.
