Confocal laser microscopy analysis of NB4 and NB4-AsR cells double-labeled with anti-PML antibodies (revealed with a Texas Red-labeled conjugate) and anti-RARα antibodies (revealed by a FITC-labeled conjugate). (A) NB4; (B) NB4-AsR; (C) NB4-AsR treated for 1 day with 10−6 mol/L RA; or (D) NB4-AsR treated for 1 day with 10−6 mol/L As2O3.
