N-terminal PEGylation of human serum albumin and investigation of its pharmacokinetics and pulmonary microvascular retention.


Human serum albumin (HSA) is used as an important plasma volume expander in clinical practice. In the present study, HSA was N-terminally PEGylated and a PEGylated HAS (PEG-HSA) carrying one chain of PEG (20 kDa) per HSA molecule was obtained. The purity, secondary structure and hydrodynamic radius of the modified protein were characterized using sodium… (More)
