Intracellular detection of IL-16 in infiltrating cells into DTH footpads.
Infiltrating cells into DTH footpads were isolated 24 hours after the Ag challenge and stained intracellularly with PE-conjugated anti-IL-16 (14.1) or isotype-matched control mAb (G155-178). For blocking, PE-conjugated anti-IL-16 was preincubated with recombinant IL-16 and used for the staining. Similar results were obtained in 3 independent experiments.
