The top expression of CD69 and CD25 in viable CD4 cells was analyzed by stream cytometry. Data are mean SD of two CE-224535 3rd party tests performed with cells CE-224535 isolated from two HIV-infected individuals on suppressive cART.(TIF) ppat.1004071.s002.tif (172K) GUID:?406967A6-6E91-4259-910D-9F55BA27FFB8 Figure S3: Insufficient HIV DNA contamination in extracted intracellular RNA samples following a treatment with DNase I. (A) Two million memory space Compact disc4 T cells isolated from three HIV-infected cART-suppressed individuals (Donors ACC) had been treated with control (empty, bk) or romidepsin (RMD) for 48 hours, cleaned, lysed, and filtered through a Qiagen shredder to acquire homogenized cell lysates before extra analyses. Cell lysates had been extracted using QIAsymphony, with or without DNase I digestive function, before the whole sample was examined by COBAS for the quantification of HIV viral sequences. (B) Cells from similar donors had been lysed, shredded, and extracted for total Mouse monoclonal to CD16.COC16 reacts with human CD16, a 50-65 kDa Fcg receptor IIIa (FcgRIII), expressed on NK cells, monocytes/macrophages and granulocytes. It is a human NK cell associated antigen. CD16 is a low affinity receptor for IgG which functions in phagocytosis and ADCC, as well as in signal transduction and NK cell activation. The CD16 blocks the binding of soluble immune complexes to granulocytes RNA using QIAsymphony with DNase We digestive function then. Examples aliquots had been examined by qPCR for HIV GAPDH and Gag sequences, with or without addition of change transcriptase RT or (RT+?). Asterisks (*) indicate non-e recognized. (C) Random lysates of vehicle-treated memory space Compact disc4 T cells from virally suppressed HIV individuals (#1C8) were split into similar duplicates and extracted for total RNA using QIAsymphony with DNase I digestive function. The full total RNA was after that treated with extra DNase I digestive function or not really (yes vs. no) before quantification of HIV viral sequences by COBAS.(TIF) ppat.1004071.s003.tif (1.2M) GUID:?232DC342-A2DA-4DFD-9D4E-31C97B355A07 Figure S4: Lack of HIV DNA contamination in total nucleic acid extracts from cell culture supernatants. Memory CD4 cells isolated from four HIV-infected cART-suppressed patients (Donors ACD) were treated with no drug control (blank; bk), 5 nM romidepsin (RMD) or PMA+ ionomycin (P/I) for 6 days. Cell culture supernatants were extracted for total nucleic acid (tNA) using COBAS TNAI kit before additional analyses. (A) HIV Gag DNA and host GAPDH DNA were quantified in tNA by qPCR without reverse transcriptase. Asterisks (*) indicate none detected. (B) The same tNA samples were further incubated with or without DNase I (yes vs. no), re-extracted for tNA, and analyzed for HIV copies by COBAS HIV viral load analyzer.
