Abstract
An improved method is described for the preparation of natural human growth hormone (hGH) in pure form, which comprises the preparation of a precursor of hGH by means of the culture of Bacillus subtilis cells transformed by a hybrid plasmid, the separation of the precursor from the total proteins, the digestion of the precursor with the enzyme Factor Xa and finally the purification of the natural hGH thus obtained from the enzymatic hydrolysis mixture.
