Figure 3.
PLA in GH3 cells showed the presentation of PIT-1 epitope by MHC class I. (A) PLA was performed using both the polyclonal anti–PIT-1 antibody [15] and anti-MHC class I antibody [18], demonstrating the presentation of PIT-1 epitope by MHC class I molecules. PLA was performed only using only anti–PIT-1 antibody [15] (B) or only anti-MHC class I antibody [18] (C). Scale bar, 10 µm.
