IgG samples exceeding the upper detection limit of 250 AU were automatically diluted 1:10 by the instrument and reanalyzed. In rare cases where this dilution was insufficient to bring values within range, a 1:100 dilution was prepared manually and subsequently analyzed on the same system.  \nFlow cytometry  \nAfter thawing, global γδ T-, B-, and NK-cell phenotypes were analyzed, and HCMV","cbCaiaV3CJy1b7Z0","https://ap.wps.com/l/cbCaiaV3CJy1b7Z0","pdf",1154042,14,"English","# Supplementary Methods\n## HCMV viral load measurements\n## HCMV-specific IgG and IgM measurements\n## Flow cytometry","[{\"question\":\"How was HCMV viral load quantified in the study?\",\"answer\":\"HCMV DNA was measured from EDTA plasma using a clinically validated real-time PCR assay with specified primers and probe, including a cloned plasmid positive control.\"},{\"question\":\"Which method was used to measure HCMV-specific IgG and IgM?\",\"answer\":\"HCMV-specific IgG and IgM were measured with clinically validated ARCHITECT CMV assays on the ARCHITECT i2000SR system, with automatic dilution for high IgG values and manual dilution when needed.\"},{\"question\":\"How were immune cell subsets analyzed by flow cytometry?\",\"answer\":\"After thawing, global γδ T-, B-, and NK-cell phenotypes were assessed, and HCMV-specific B cells were quantified using stained PBMCs with specified antibody panels and viability dye.\"}]","Human cytomegalovirus control in allogeneic stem cell transplant recipients in the letermovir era - emerging humoral and cellular players | PDF",1791015777,35]
