Abstract

A sensitive and selective high-performance analytical method based on capillary zone electrophoresis (CZE) was developed for investigating interactions between heparin and programmed cell death 5 (PDCD5) qualitatively and quantitatively. The binding constant of the interaction between PDCD5 and heparin calculated by Scatchard analysis was 4.17 × 10⁴ M^-1 and the binding sites located in the C-terminal region of PDCD5 (residues 109-115). The precisions of migration times, peak heights and binding constants, expressed as the relative standard deviation, were less than 2.4%, 1.1% and 5.7%, respectively.
