摘要:
The present invention relates to a method for mass-production of target protein, particularly to a method for mass-production of trombopoietin by regulating the expression of chaperone protein.
摘要:
The present invention relates to novel human thrombopoietin (hTPO) derivatives, and to process of preparation thereof. Particularly, sugar chains are introduced into native hTPO by substituting amino acids such as asparagine for amino acids at specific positions in native hTPO, preparing novel hTPO derivatives with high activities enhancing the platelet production in vivo. Therefore, the novel hTPO derivatives of this invention may be useful for the treatment of thrombocytopenia associated with anticancer therapy or the transplantation of bone marrow.
