Yields of total IGF-I in 10-liter fermentations. The peak titers of IGF-I were measured by reversed phase HPLC after guanidine hydrochloride and DTT extraction. Fermentations containing overexpressed Dsb protein are denoted by w/Dsb. Results from at least three (n = 3–5) separate fermentations were averaged. The bars correspond to the standard error of the mean.
