Application: |
Flow cytometry |
Cells used: |
Draining lymph nodes from ovalbumin/alum-immunized mouse transferred with ovalbumin-specific CD45.1+ CD4 T cells (OTII) |
Brief Protocol: |
Three millions cells were prepared in FACS buffer (PBS/Bovine Serum Albumin 1% / 0.1% azide) were plated in round-bottom 96-well plates. Cells were spin down and treated with Fc block (5% of supernatant from a 2.4 G2 hybridoma culture in FACS buffer), for 10 min at 4°C. Cells were spin down and stained in 25 µl of FACS buffer with APC/Cyanine7 anti-CD44 (1:200), BV510™ anti-CD45.1 and BV421™ anti-CD4 during 20 min at 4°C in the dark. Cells were washed twice with 150 µl of FACS buffer PBS/BSA, and resuspended in FACS buffer for analysis by flow cytometry. |
Results Summary: |
activated OTII cells stain positive (grey histogram) while OTII from naïve mouse are negative (dashed histogram) |
Additional Notes: |
T cell activation/memory marker for flow cytometry. Easy to use but the compensations with APC needs to be checked. |
