(A) Depiction of different types of COMETs. (B) HEL cells treated with (1) 10 μmol/L GSNO (10× magnification); (2) 50 μmol/L GSNO (40× magnification); (3) 100 μmol/L GSNO; (4) cytokines to stimulate iNOS; and (5) cytokines in the presence of L-NMMA. YOYO-1 DNA stain was used on all parts of Figure 4.
