The following conjugated Abs were used for cell surface staining: CD3-Pacific Blue (clone UCHT1), CD4-Alexa Fluor 700 (clone RPA-T4), CD8-APC-H7 (clone SK1), CD160-Alexa Fluor 647 (clone BY55), T-cell immunoglobulin and mucin-domain containing-3 (TIM-3)-PE-CF594 (clone 7D3), 2B4-FITC (clone 2–69) (BD Biosciences, San Jose, CA), and programmed cell death protein-1 (PD-1)-PE (clone J105) (Thermo Fisher Scientific). Conjugated Abs for intracellular staining included the following: cytotoxic T lymphocyte antigen-4 (CTLA-4)-PE-Cy5 (clone BNI3), granzyme B-PE-CF594 (clone GB11), interferon-gamma (IFN-γ)-PE-Cy7 (clone B27), interleukin-2 (IL-2)-APC (clone MQ1-17H12), tumor necrosis factor-alpha (TNF-α)-Alexa Fluor 488 (clone MAb11) (BD Biosciences, San Diego, CA), and perforin-PE (clone B-D48) (Abcam, Cambridge, UK). All conjugated Abs were titrated and multicolor panels for flow cytometry assays were approached as previously reported [38 (link)]. The following purified (No azide/Low endotoxin) Abs were used in cultured cells: CD28 (clone CD28.2) and CD49d (clone 9F10) (BD Biosciences).

All conjugated antibodies were titrated as previously reported [29 (link)]. The multicolor panels used for the flow cytometry assays were utilized according to the fluorescence minus one control (FMO) method as recommended [29 (link)]. In addition, the following purified NA/LE antibodies were used for cell culture: CD28 (clone CD28.2) and CD49d (clone 9F10) (BD Biosciences).

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.
