Product Overview
Description:
Fisetin-d5 is a penta-deuterated stable isotope internal standard optimized for the absolute mass spectrometry-based quantification of native fisetin profiles via GC-MS or LC-MS assays. The corresponding un-labeled analyte is a naturally occurring polyphenolic flavonoid that demonstrates robust radical scavenging capacity within Trolox equivalent antioxidant assays and completely blunts fMLP-stimulated oxidative burst in isolated human polymorphonuclear neutrophils at a 10 µM threshold.
Labeling:
Stable isotope-labeled
