Process for manufacturing crystals of growth hormone and crystals thereby obtained

(57) Summary book invention about the new method for manufacturing the crystalline of growth hormone (GH) or its functional derivative, The method iGH or its functional derivative Buffer and a general formula (1), It mixes with the water solution consisting of the chemistry compound which has Ar* *CRR* *CRR* *CRR*OH (1), among a formula, H, OH or アルキル, and n and m are 0 or 1, and phenyl, alkyl substitution phenyl, Naff Chill, alkyl substitution Naff Chill, and R*R carry out ii 定温 neglect of the Ar -- iii -- it consists of a process of isolating a crystalline by a well-known method. The needle which the present invention relates to the crystalline of GH from buffer solution again, and has a length of at least 20 microns, It is related with the suspension for pouring, precipitation preparation, and dry preparation which consist of use of the chemistry compound which has a general formula (1) in manufacture of the crystalline of growth hormone or its functional similar thing in the form of triangle form, a cube, or a parallelepiped, and a crystalline.
