Cells were sorted on a BD influx (BD Biosciences). Single-cell suspensions of freshly purified naïve CD8+ T cells and activated CD8+ T cells were incubated with PBS containing 1% FBS and then stained with the indicated antibodies for 30 min on ice. Staining reagents included FITC anti-CD8 (53-6.7) (BD, 553031), eFluor 450 anti-CD44 (IM7) (eBioscience, 48-0441-82), APC anti- CD62L (MEL-14) (eBioscience, 47-0621-82), APC anti-PD-1 (J43) (BD, 562671) and PE anti-TIM-3 (5D12) (BD, 566346). Dead cells and cell aggregates were excluded from analyses by Fixable Viability Dyes eFluor™ 506 (eBioscience, 65-0866-18) and FSC-H/FSC-A characteristics. Gating criteria were as follows: for Tn: CD8+, CD44, CD62L+; for Teff1 and Teff2: CD8+, PD-1+, TIM-3; for Tex: CD8+, PD-1+, TIM-3+.

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.
