To determine chimerism, splenocytes were stained with anti‐H‐2Dd‐FITC (clone: 34–2–12) and anti‐H‐2Db‐PE (clone: KH95) (all from Biolegend). Treg cells were determined in the spleens according to manufacturer's instructions using a kit from eBioscience (San Diego, CA). Spleen cells were also characterized using anti‐CD11b (clone: M1/70), anti‐CD11c (clone: N418), anti‐B220/CD45R (clone: RA3‐6B2), anti‐I‐A/I‐E (clone: M5/114.152), anti‐CD4 (clone: RM4‐5 and GK1.5), anti‐pDCA1 (clone: 927), anti‐CD8α (clone: 100712), anti‐TCR‐β (clone: H57‐597), all from Biolegend, and a viability marker (LIVE/DEAD® Fixable Near‐IR Dead Cell Stain Kit, Life Technologies, Eugene, OR). For MACS cell purification, we used anti‐CD11c (cat. 130‐052‐001), anti‐CD4 (cat. 130‐049‐201), and anti‐CD8 (cat. 130‐049‐301) microbeads (Miltenyi Biotec Bergisch Glabach, Germany). For the in vitro functional assays, DC subpopulations were purified from spleens by MACS. CD11c cells were then sorted by FACS (BD FacsAria III) using APC/Cy7‐labeled anti‐B220, PercP‐labeled anti‐I‐A/I‐E, APC‐labeled anti‐pDCA1, PE‐labeled anti‐CD11b and PE/Cy7‐CD8a. We obtained 90.9 ± 1.35% purity for CD8αcDCs, 95.1 ± 1% for CD11b cDCs and 94.± 0.3% for pDCs. All cells were acquired using a FACS‐LSRFortessa according to BD bioscience protocols and analyzed by FlowJo software version 9.8.1.

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.
