Tissues were harvested after perfusing Il21-mCherry/Il2-emGFP TG mice with 4% paraformaldehyde (PFA, pH 7.4 at 4 °C), tissues were further fixed in 4% PFA at 4°C for 2 hours, placed in 30% sucrose for 24 hours, and embedded in OCT compound (Tissue-Tek) for freezing. 10-µm thick frozen tissue sections were rehydrated, blocked with 10% rat serum in 0.1% Tween20/PBS (PBST) for 1 hour at room temperature, and stained with the Alexa Fluor 647 anti-mouse B220 antibody (clone RA3–6B2, Biolegend) in 1% rat serum/ 0.1% PBST overnight at 4 °C. Nuclei were stained with 4’,6-diamidin-2-fenilindolo (DAPI). Images were acquired using a Leica TCS SP5 microscope (Leica Microsystems, Mannheim, Germany) using a 20x objective NA .7, zoom 1X and processed with Imaris software 9.0.0 (Bitplane AG, Zurich Switzerland).

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.
