  • Process for preparing human relaxin-2
    Patent number: 9434780
    Abstract: A process for preparing human relaxin-2 having the following amino acid sequence: A chain: (SEQ?ID?NO:?1) pGlu-Leu-Tyr-Ser-Ala-Leu-Ala-Asn-Lys-Cys-Cys-His- Val-Gly-Cys-Thr-Lys-Arg-Ser-Leu-Ala-Arg-Phe-Cys B chain: (SEQ?ID?NO:?2) Asp-Ser-Trp-Met-Glu-Glu-Val-Ile-Lys-Leu-Cys-Gly- Arg-Glu-Leu-Val-Arg-Ala-Gln-Ile-Ala-Ile-Cys-Gly- Met-Ser-Thr-Trp-Ser; comprising the following steps: providing the amino acids necessary for the synthesis of the A and B chains with usual protective groups, wherein the cysteines are employed as trityl-protected amino acids (L-Cys(Trt)-OH); effecting a chromatographic purification of the individual chains A and B after the solid state synthesis; followed by the simultaneous folding and combination of the individual chains A and B in ammonium hydrogencarbonate buffer at pH 7.9 to 8.4; and subsequent purification of the relaxin-2 formed.
