Identification of disulfide bond-linking sites in biosynthesized platelet factor 4 by establishing a partial reduction method without alkylation


ABSTRACT: In this research, a bacterial expression system was established to efficiently generate recombinant human PF4 (rhPF4), and the accuracy of the sequence was validated by liquid chromatography-high-resolution mass spectrometry. A relatively straightforward alkylation-independent partial reduction approach was developed to identify the two disulfide bond sites in PF4, which are critical for its structural integrity and functionality.
