Tcr gd fitc b1

Manufactured by BioLegend

TCR-gd-FITC (B1) is a fluorescent-labeled monoclonal antibody that binds to the gamma-delta T cell receptor (TCR) on human cells. This antibody is conjugated with the fluorescent dye FITC (Fluorescein Isothiocyanate) and can be used to detect and analyze gamma-delta T cells in flow cytometry applications.

PBMC were thawed at 37°C, transferred into pre-warmed complete RPMI10 culture medium, pelleted by centrifugation, resuspended in RPMI10, and left to rest at 37˚C for 1.5 h. Cells were stained with a cocktail of cell surface antibodies in FACS buffer (PBS + 2% FCS) for 30min at room temperature (RT) in the dark. Cells were washed and resuspended in FACS buffer, 7AAD viability dye (Biolegend) was added, and cells were acquired on a BD FACSymphony A5 flow cytometer (BD Biosciences). Data were analysed by FlowJo V10 (BD Biosciences). The following anti-human flow cytometry antibodies were used: TCR-gd-FITC (B1, Biolegend), CD19-PerCP-Cy5.5 (HIB19, Biolegend), CD14-PE (M5E2, Biolegend), CD56-PE-CF594 (NCAM16.2, BD Biosciences), CCR7-PE-Cy7 (G043H7, Biolegend), PD-1-AF700 (EH12.2H7, Biolegend), CD45RO-APC-Cy7 (UCHL1, BD Biosciences), CD127-BV421 (A019D5, Biolegend), CD28-BV480 (CD28.2, BD Biosciences), CD20-BV605 (L27, BD Biosciences), CD16-BV650 (3G8, BD Biosciences), HLA-DR-BV711 (L243, Biolegend), CD4-BV786 (SK3, Biolegend), CD3-BUV395 (UCHT1, BD Biosciences), CD8-BUV496 (RPA-T8, BD Biosciences), CD25-BUV737 (2A3, BD Biosciences).

Comprehensive Immunophenotyping of T-cells

Extracellular staining was performed to evaluate purity, double positive for CD3-phicoeritrin (Hit3a, BioLegend), CD8-FitC (Hit8a, BioLegend), and TCRg/d-FitC (B1, BioLegend). The naive state of the cells was evaluated by low CD45RO (UCHL1, Tonbo) and by high CD45RA (T6D11, Miltenyi Biotec). For cytokine staining, we used IL-2-APC (MQ1-17H12BD, Pharmingen) and Miltenyi Biotec) . To quantify TLR5 (85B152.5, Abcam), extracellular staining was performed. For cytotoxicity markers, GZMB (GB11, BioLegend) and CD107a (H4A3, Miltenyi Biotec) intracellular staining was performed. For assays of cell division, PBMCs were specifically evaluated by double staining with CFSE (21888, Sigma) 50 nM and CD8-Alexa Fluor 405 (MHCD0826, Life Technologies) or only CFSE in purified CD8 + T cells. For assays of oxidative burst, non-fixed CD8 + T cells were stained with 50 nM dihydroethidium (D7008, Sigma) for 20 min at 37 C, then analyzed immediately on the cytometer.

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.
