Human interferon-α8 was expressed in Saccharomyces cerevisiae and found to accumulate intracellularly in an insoluble form. The protein could be solubilized and converted to a biologically active form with high yield by a denaturation-refolding procedure. The interferon-α8 was further purified to apparent homogeneity by copper-chelate affinity chromatography and anion-exchange chromatography and...
The invention relates to DNA sequences that code for the amino acid sequence of the thrombin inhibitor hirudin, hybrid vectors containing such DNA sequences, host cells transformed with such hybrid vectors, novel polypeptides with thrombin-inhibiting activity produced from such transformed host cells, processes for the manufacture of these DNA sequences, hybrid vectors and transformed host cells,...
