Application

β-Estradiol 3-(β-D-glucuronide) sodium salt has been used in estrogen administration. It has also been used to determine the amount of two types of glucuronidated estradiols such as estradiol-3- α glucuronide and estradiol-17- β glucuronide.

This study investigated a high-throughput assay to measure multidrug resistance-associated protein (MRP1)-mediated uptake into membrane vesicles. Typically, a rapid filtration technique using a 12-filter vacuum manifold is used. We report here the development of a 96-well microtiter dish assay. MRP1-transfected

Our aim was to develop a statistical method to correct for non-parallelism in an estrone-3-glucuronide (E1G) enzyme immunoassay (EIA). Non-parallelism of serially diluted urine specimens with a calibration curve was demonstrated in an EIA for E1G. A linear mixed-effects analysis

Traditionally, the Michaelis-Menten equation has been used to determine kinetic parameters for in vitro glucuronidation assays. Recently, estradiol-3-glucuronide formation was shown to exhibit non-Michaelis-Menten kinetics consistent with autoactivation. A concern with the observation of nontraditional kinetics is that they may
