hGH AND METHODS FOR PREPARING hGH

摘要

Preparations of recombinant human growth hormone (hGH) are provided having a purity that comprises 2% or less of a peptide other than native human growth hormone (e.g., essentially free of multimeric forms) are disclosed. Active pharmaceutical ingredient (API) preparations of recombinant hGH suitable for commercial production of formulation grade recombinant hGH are provided. A stable Master Cell Bank of transformed E. coli is also disclosed, as well as methods for creating a transformed E. coli preparation that includes a Met-AsphGH encoding sequence. Improved manufacturing methods are also presented that are suitable for large scale production of highly purified preparations of recombinant human growth hormone.
