实验过程

The expression of the TG-1 F cells on pMORPHx9-FS-coded Fab fragments in E. coli was performed in shaking bottle cultures with 0.75 l of 2×TY medium and 34 μg/ml of chloramphenicol. After induction with 0.75 mmol of IPTG, the cells were cultivated for 16 hours at 30° C. As an alternative, Fab clones, which had been obtained from the second maturation pool 2, were induced with 0.1 mmol of IPTG and then cultivated at 22° C. Periplasmatic extracts from cell pellets were produced by osmotic shock, and the Fab fragments were isolated by Strep-Tactin® chromatography (IBA, Göttingen, Germany). The apparent molecular weights were determined by size-exclusion chromatography (SEC) with calibrating standards. The concentrations were determined by UV spectrometry.
