A single-cell suspension was prepared from mouse LNs and spleens (both male and female mice, 6 to 8 weeks old). For the lung tissues, lungs were cut into small pieces and then digested for 20 min using digestion buffer containing collagenase IV, hyaluronidase, and deoxyribonuclease I. For γδT17 cell polarization, CD27 γδ T cells from LNs were cultured with IL-1β (10 ng/ml) and IL-23 (10 ng/ml) for 7 days in wells precoated with anti–γδ TCR monoclonal antibody (mAb) (clone: UC-7). For γδT1 cell polarization, sorted CD27+ γδ T cells from pooled LNs and spleens were cultured with IL-2 (10 ng/ml) and IL-7 (10 ng/ml) for 7 days in wells precoated with anti-CD3 mAb (clone: 145-2C11). In some experiments, dimethyl 2-oxoglutarate (α-KG, Sigma-Aldrich), N-acetyl-l-cysteine (Sigma-Aldrich) were added during the culture. γδT17 and γδT1 cells were further sorted from cultures based on CD27 expression. Cells were sorted using FACSAria III cell sorter (BD Biosciences). The detailed commercial Ab information is listed in table S1.

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.
