DCs were assessed using the antibodies of anti-CD11c-PC5.5; anti-CD80-FITC; anti-HLA-DR-APC-Cy7 and anti-CD86-PE-Cy7. PBMCs or ILC2s were stained with Fixable Viability Dye-eF506 and the following specific mAbs: Lineage cocktail (CD2, CD3, CD14, CD16, CD19, CD56, CD235a, FceR1)-FITC (all from eBioscience, San Diego, Calif, USA); anti-CRTH2-PE (BD Pharmingen, USA) and anti-CD127-PE-Cy7 (eBioscience, San Diego, Calif, USA). For intracellular cytokine assay, PBMCs or ILC2s were stimulated with phorbol myristate acetate (PMA), ionomycin, and brefeldin A (BFA) for 5 h, and then, the cells were fixed, permeabilized, and stained with anti-IL-13-BV421 (BioLegend, San Diego, CA, USA). For GATA3 levels detection, the cells were processed with the FoxP3/Transcription Factor Staining Buffer Set before staining with anti-GATA3-BV421(BioLegend, San Diego, CA, USA). After staining, samples were analyzed on a CytoFLEX Flow Cytometer (Beckman Coulter, Hercules, CA, USA).

Testes were collected from adult C57BL/6 (JAX®mice, stock no. 000664) mice and enzymatically and mechanically dissociated into a single cell suspension enriched for interstitial cells as described above. The single cell suspension is stained with a series of cell surface markers including anti-CD8-BV570 (1:300; Biolegend 100739), anti-CD3-PE/Cy7 (1:300; Biolegend 100219), anti-CD4-BV510 (1:300; Biolegend 100449), anti-IL7r-PE/Cy5 (1:300; Biolegend 135015). However, for intracellular staining - the ILCII cells were first incubated with PMA (10 ng / mL), ionomycin (10 μM), with the addition of Golgi-stop reagent (BD Bioscience, San Jose, CA) for 4 h at 37°C and subsequently stained for anti-IL4-PE (1:300; Biolegend 504103), anti-IL-13-APC (1:300; Novus 011818), and anti-Gata3-BV421 (1:300; Biolegend 653813) for 30 minutes prior to flow cytometry.

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.
