摘要

Abstract

The fluorescence property of bovine serum albumin was investigated in the presence of PEGs of different molecular weights. Based on our results

we propose that PEGs of different molecular weights bind to albumin in the pH 7.4 aqueous solution

but only when the polymer size is larger than the protein size

one polymer chain may bind to multiple proteins and cause the proteins to aggregate.
