Co-localization of NQO1 with microtubules in 16HBE cells.

<p>Co-immunostaining for NQO1 (A180) and α-tubulin showing co-localization on microtubules. (A) Co-localization of NQO1 with α-tubulin using fluorescently-labeled secondary antibodies. (B) Co-localization of NQO1 with α-tubulin/acetyl α-tubulin using PLA-based detection. Immunostaining was performed as described in <i>Materials and methods</i>.</p>
