SDS-PAGE (12% Tris glycine-HCl gel) analysis of purified single chain antibody fragments (scFvs) from clones (I5-4, I5-7, I5-8 and I50-5) isolated from Tomlinson I library. The position of the bands appears to indicate that the molecular weight of the expressed scFv fragments is approximately 26–28 kD.
