摘要
A serial gel filtration operation with the combination of G25 and G100 in one column was developed to remove salt and PEG from upper phase rich in recombinant human tumor necrosis factor α after simultaneous cell disruption and two-phase aqueous extraction. Buffer exchanging and primary purification were also achieved at same time. The purification factor of 4.4 was obtained with an activity recovery of 97% by one single step of serial operation.
