Single-cell lymphocyte solutions were prepared from organs as indicated and resuspended in staining buffer containing 5% FBS in HBBS. Pre-enrichment of splenic lymphocytes was performed using PE-labeled CD8+ T cell magnetic bead positive selection according to the manufacturer instructions (RoboSep, STEMCELL Technologies). Splenic and brain-resident lymphocytes were identified using mAbs against the following Ags, all from BioLegend unless otherwise noted: PE-CD8α (MAR1), FITC-CD4 (RM4–5), BV711-CD11b (M1/70), BV421-CD45.2 (1D4), allophycocyanin/Cy7-CD45.2 (1D4), and allophycocyanin-TCRβ, (H57–597; eBio science). Samples were sorted on an FACSAria III SORP (BD Biosciences) equipped with violet (403 nm, 100 mW), blue (488 nm, 100 mW), yellow-green (561 nm, 50 mW), and red (638 nm, 150 mW) lasers, then analyzed with FlowJo (Tree Star). Pre- and postsort purity of CD8+ T cells are shown in Fig. 1A.

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.
