Surface staining was carried out by standard procedures for our laboratory as described [56 (link)]. Except where noted, all reagents were obtained from BD Biosciences (San Diego, CA) and included monoclonal antibodies to the following molecules: CD3 (clone SP34-2, APC-Cy7 conjugate) CD4 (clone SK3, PerCP-Cy5.5 conjugate), CD8α (clone RPA-T8, Alexa700 conjugate) CD28 (clone CD28.2, PE-Texas Red conjugate, Beckman-Coulter, Fullerton, CA), CCR7 (clone 150503, Pacific Blue conjugate, custom) CXCR3 (clone 1C6, PE-Cy5 conjugate), Ki-67 (Clone B56, PE conjugate), CD127 (clone R34.34, PE conjugate, Beckman-Coulter), perforin (clone Pf-344, FITC conjugate, Mabtech, Mariemont, OH). Intracellular staining for perforin expression was performed using Caltag Fix & Perm (Invitrogen, Camarillo, CA) according to the manufacturer’s suggested protocol. Enumeration of SIV-specific cells using PE- or APC-conjugated pentamers to Mamu-A*01 Gag181-189CM9 and Tat28-35SL8 (Proimmune, Oxford, UK) was performed as described previously [57 (link)]. All samples were analyzed using an LSR II (BD Biosciences), and analyses were performed using FlowJo software (Tree Star Inc., Ashland, OR). Isotype-matched controls and/or fluorescence-minus-one (FMO) controls were included in all assays [58 (link)].

Single-cell suspensions from gingival tissues, or buccal mucosa, were untreated or stimulated for 3.5h with or without PMA (50 ng/ml; Sigma) and ionomycin (2.5 μg/ml; Sigma) in the presence of brefeldin A and then stained for cell surface makers and/or intracellular cytokines. Cells were stained with Live/Dead Cell Viability assay (Invitrogen) and different combinations of the following anti-human antibodies: CD34, CD16, CD11c, CD294 (CRTH2), EpCAM (BD Biosciences); CD127 (Beckman Coulter); CD1a, CD3, CD14, CCR7, CD335 (NKp46), CD336 (NKp44), Singlec-8, FcεR1α, (Biolegend); CD1c, HLA-DR, CD45, CD4, CD8, TCRγδ,CD45RO, CD45RA, CD161, CD56, CD19, CD20, CD117, CD15, CD69 , Foxp-3, IL-17A, IFN-γ (eBioscience); and CD141 (Miltenyi Biotec). All samples were analyzed using a FACS Fortessa cytometer (BD Biosciences). Data analysis was performed using FlowJo software (Treestar).

Surface staining was carried out by standard procedures for our laboratory as described [30 (link)]. Except where noted, all reagents were obtained from BD Biosciences (San Diego, CA) and included monoclonal antibodies to the following molecules: CD3 (clone SP34-2, APC-Cy7 conjugate) CD4 (clone SK3, PerCP-Cy5.5 conjugate), CD8α (clone RPA-T8, Alexa700 conjugate), CD28 (clone CD28.2, PE-Texas Red conjugate, Beckman-Coulter, Fullerton, CA), CCR7 (clone 150503, Pacific Blue conjugate, custom), KI-67 (clone EH12.2H7, PE conjugate, custom), CD127 (clone R34.34, PE conjugate, Beckman-Coulter), perforin (clone Pf-344, FITC conjugate, Mabtech, Mariemont, OH). Intracellular staining for perforin and KI-67 expression was performed using Caltag Fix & Perm (Invitrogen, Camarillo, CA) according to the manufacturer’s suggested protocol. Enumeration of SIV-specific cells using PE- or APC-conjugated tetramers to Mamu-A*01 Gag181–189CM9 and Tat28–35SL8 (kindly provided by Nancy Wilson and David Watkins, Wisconsin National Primate Research Center, Madison Wisconsin) was performed as described previously [31 (link)]. All acquisitions were made on an LSR II (BD Biosciences) and analyses were done using FlowJo software (Tree Star Inc., Ashland, OR). Isotype-matched controls and/or fluorescence-minus-one (FMO) controls were included in all assays [32 (link)].

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
