The HPLC-ECD/UV unit represents the first established unit and the basis under which the Division was first founded. The unit hosts eight HPLC systems, most of which are equipped with electrochemical detectors (ECD). Under the supervision of Dr. Lattke, the unit is devoted principally to routine laboratory analytics, with assays covering urinary metanephrines, catecholamines, homovanillic acid, vanillylmandelic acid 5-hydroxyindloeacetic acid, as well as several other methods utilizing UV detection for measurements of drugs and vitamins. Under the additional co-supervision by Dr. Nan Qin, the unit’s Chief analyst who also heads the Cell Biology unit, three of the HPLC systems are dedicated to supporting the Division’s research into catecholamine systems. This includes established methods for measuring catechols (norepinephrine, epinephrine, dopamine, 3,4-dihydroxyphenylglycol, 3,4-dihydroxyphenylalanine and 3,4-dihydroxyphenylacetic acid) in plasma, urine, CSF and tissue samples. Assays to quantify activities of enzymes involved in catecholamine synthesis and metabolism (e.g., tyrosine hydroxylase, catechol-O-methyltransferase) are also available to support the research of the Division and collaborating investigators.
