(B) Total lysates from Δapg5 cells with HAAPG10 and/or MycAPG12 on 2μ plasmid were immunoprecipitated with anti‐HA (mAb 16B12) or anti‐Myc (mAb 9E10) antibody. Precipitates were analyzed by Western blotting using anti‐HA or anti‐Myc antibody. Apg12p adduct of Apg10p is indicated by ● and an unidentified complex of 67 kDa by ●●. The positions of cross‐reacting IgG heavy chain (H) and light chain (L) are indicated by arrowheads.
