Binding Capacity of Human Serum Albumin with Estrogen and Other Ligands

Human Serum Albumin이 Estrogen과 기타 Ligands와의 결합력에 관한 연구

Abstract

This study was trying to find what physical changes occurred to albumin when it reacted with estrogen and other ligands. Each concentration of human serum albumin with 100$\mu$l estradiol reacted at the highest binding capacity of 280nm. In addition, 1 hr of reaction time showed the highest binding rate. Conformational changes in human serum albumin with dietylstillbesterol and N-ethyl-maleimide produced strong binding capacities. The changes were immediate and they did not increase or decrease over time. Effects of human serum albumin with estriol induced no interaction each other. The binding capacity of human serum albumin with vitamin D$_2$was lower than estradiol. and the highest binding rate showed 1 hr of reaction time. Vitamin D$_2$ was very similar to the binding capacity of estradiol.
