PBMC were isolated from peripheral blood by Ficoll gradient and frozen for batched analysis. We designed six multicolor flow cytometry panels to quantify 60 T cell subsets along with two B cell subsets, and calculated the CD4+/CD8+ T cell ratio (Supplementary Table 1). The following fluorochrome-conjugated anti-human antibodies were used from BD Biosciences (San Jose, CA): CD3-FITC, CD3-PerCP-Cy5.5, CD4-APC, CD4-APC-Cy7, CD8-BV510, CD45RO-FITC, CD45RA-APC, CD45RA-APC-Cy7, CCR4-PE, CD27-PE, CD28-BV421, CD138-BV421, CCR6-BV421, CXCR3-PE, CCR7-A700, IL-17-BV786, IFN-γ-PE-Cy7, iso IgG1k-FITC, iso IgG1k-PE-Cy7, iso IgG2bk-APC, iso IgG1k-APC-Cy7, and iso IgG1k-BV510; from Biolegend (San Diego, CA): CD127-FITC, CD27-APC, CD57-PerCp-Cy5.5, CD19-BV510, PD-1-APC-Cy7, CXCR5-FITC, and TNFα-FITC; from eBioscience (San Diego, CA): CD4-PE-Cy7, and IL-2-PE; from Miltenyi Biotec (San Diego, CA): CD25-APC and KLRG1-PE; from Beckman Coulter (Brea, CA): CD38-PE-Cy7.

Flow Cytometry Immunophenotyping Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
Flow cytometry was performed at the LIM/60, Laboratorio de Imunologia Clinica e
Alergia, Universidade de Sao Paulo, Sao Paulo State, Brazil. Briefly, frozen
PBMC were thawed in a 37 ºC water bath and cells were counted (1x106/
tube) and incubated with the following conjugated monoclonal antibodies: (I)
Invitrogen (Carlsbad, California, USA): CD3 phycoerythrin (PE)-Texas Red; (II)
BD Biosciences Pharmingen (San Diego, California, USA): CD8 Brilliant violet
(BV) 605, CD38 allophycocyanin (APC); (III) Biolegend (San Diego, CA, USA):
HLA-DR Alexa fluor 700, CD127 PE-Cy5, PD-1 APC-Cy7, CD28 BV 785, CD57
PerCP-Cy5.5; (IV) eBioscience (Carlsbad, CA, USA): TIGIT. Live dead amine aqua
dye (Invitrogen, Carlsbad, CA, USA) was used to exclude dead cells. The analyses
were performed using FlowJo software (version 10, TreeStar Inc., Ashland, USA),
and a representative strategy used to analyze the T cell populations is shown in
Figure 2.

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.
