Detection of Meteorin‑like/METRNL in Neuro‑2A Mouse Cell Line by Flow Cytometry. Neuro‑2A mouse neuroblastoma cell line was stained with Rat Anti-Mouse Meteorin‑like/METRNL PE‑conjugated Monoclonal Antibody (Catalog # IC6679P, filled histogram) or isotype control antibody (Catalog # IC013P, open histogram). To facilitate intracellular staining, cells were fixed and permeabilized with FlowX FoxP3 Fixation & Permeabilization Buffer Kit (Catalog # FC012).
