Bile Acid Analysis in Various Biological Samples Using Ultra Performance Liquid Chromatography/Electrospray Ionization-Mass Spectrometry (UPLC/ESI-MS)
Time of Update: 2020-11-29
However, to date, it has been difficult to know the precise roles of BA due to variations in BA molecules including conjugated forms.
Consequently, we established a rapid and reliable method, using UPLC/ESI-MS, for the analysis of BAs in various biological samples including liver, bile, blood, intestinal contents, and feces.
Analysis of Defense Signals in Arabidopsis thaliana Leaves by Ultra-performance Liquid
Time of Update: 2020-11-09
Defense signaling compounds and phytohormones play an essential role in the regulation of plant responses to various environmental abiotic and biotic stresses.
The major hormones involved in the regulation of these responses are 12-oxo-phytodienoic acid (OPDA), the pro-hormone jasmonic acid (JA) and its biologically active isoleucine conjugate (JA-Ile), salicylic acid (SA), and abscisic acid (ABA).
