Granulocyte cystine assay
WebMethod: Granulocytes were isolated from heparinized blood by isopycnic centrifugation. After lysis and deproteinization, the concentration of di-butylated cystine was measured by HPLC-ESI-MS/MS, using deuterium labelled, d6-cystine, as internal standard. Results: The assay was linear to at least 50 μmol/L with a good precision. Within-day and ... WebNeutrophil testing can now be ordered through Connect. See below for additional ordering information.
