ABSTRACT
The Nano ultra-high performance liquid chromatography-electrospray ionization mass spectrometry tandem mass spectrometry(UPLC-ESI-MS/MS) was used to characterize the primary protein. Samples were digested by trypsin, followed by liquid chromatography-tandem mass spectrometry analysis and database search. Five peptides matched with tumor necrosis factor receptor and seven peptides matched with human IgG1 fragment of the Fc. Further analysis demonstrated that seven peptides all matched with the IgG1 Fc but only partly peptides matched with the other subtypes. RhTNFRFc is fused by IgG1 Fc but not other subtypes.
