Figure 5. TpsnΔEx3 does not reduce MHC class I expression on HeLa cells.
A. Stable transfectants of HeLaM, or M553, cells containing empty vector or tpsnΔEx3 were analyzed for tapasin protein by Western blot using TO-3 antibody. B. The effect of stable tpsnΔEx3 expression on MHC class I expression on the surface of HeLaM cells was determined using W6/32 (HLA-A, -B, -C) or CR11-351 (HLA-Aw68).
