Hi everybody,
I am doing some staining for IL-2R and got surprised to see that, in spite
of having many proliferating T-cells (as assessed by 7-AAD), the percents of
IL-2R positive cells are low. Comments? Thank you very much for your attention.
Activated, proliferating cells can shed IL-2R. An example is various forms of lymphocytic
alveolitis, where the percentage of alveolar T cells expressing IL-2R is low, but soluble IL-2R
may be detectable in the BAL. You don't give any more details of your system or what cells
you are looking at, but maybe you could look at soluble IL2-R.
