An efficient and productive isolation method for human recombinant tumor necrosis factor alpha from Escherichia coli cells was developed. The method includes a membrane filtration step, two steps of ion-exchange chromatography, and gel filtration on a Sephadex G-25 column. The target product was obtained with approximately 50% total yield and greater than 95% purity according to PAGE and HPLC.
