Quantitation of Homovanillic Acid (HVA) and Vanillylmandelic Acid (VMA) in Urine Using Gas Chromatography-Mass Spectrometry (GC/MS)

Neuroblastoma, in most cases, is characterized by increased production of catecholamines and their metabolites. Laboratory diagnosis and clinical follow-up include the measurement of urinary homovanillic acid (HVA) and vanillylmandelic acid

Fluorescence Assays for Measuring Fatty Acid Binding and Transport Through Membranes

(flip-flop) is typically measured directly, using a pH-sensitive fluorophore such as 8-hydroxypyrene-1.3.6-trisulfonic acid or 2′,7′-bis -(2-carboxyethyl)-5-(and-6)- carboxyfluorescein. These probes detect the release of protons from unionized FA
