PURPOSE: The present mass cytometry panel 1, 2 was designed to simultaneously assess the ex vivo expression of 2 calcium (Ca2+)‐sensors and 4 Ca2+‐channels, the key components of the T cells “Ca2+‐toolkit,” in murine conventional (Tconv) and Foxp3+ regulatory (Treg) T‐cell subsets, including both naive and activated populations (Table 1), after a validation step of the selected antibodies (Abs, listed in Table 2) by flow cytometry.

CELL TYPE: Primary murine lymphocytes from spleen and lymph nodes

MACHINE: BD LSR Fortessa & Fluidigm CyTOF 1
