Spheroid section from H520 cells immunohistochemically stained using an anti-p39 antibody. (a) Negative control section in which the primary antibody was omitted. (b) Primary antibody at a 1:50 dilution and at 40x magnification. (c) Primary antibody at a 1:50 dilution and at 100x magnification. Staining is observed as a strong brown signal (b and c), which is absent from the negative control (a).
