Methodology flow chart on the selection of tumor binder scFv fragments by ELISA. The flow chart presents the new tumor infiltrating B cell antibody fragment phage display technology. It describes the biotechnological processes and our detection system. A master plate was prepared that enabled the detection of our scFvK phage display library in a soluble scFv and a phage displayed scFv form after rounds of panning reactions. Antibody fragments could be selected in the course of an ELISA using 95 well maxisorbe plates precoated with native cancer membrane preparations.
