  • 4% paraformaldehyde-fixed A431 (human epidermoid carcinoma cell line) cells stained for NUCB2 (green) using ab229683 at 1/500 dilution in ICC/IF.

    Nuclear counterstain: Hoechst 33342 (blue).

  • NUCB2 was immunoprecipitated from HEK-293T (human epithelial cell line from embryonic kidney transformed with large T antigen) whole cell extract with 5 µg of ab229683. Western blot was performed from the immunoprecipitate using ab229683. Anti-Rabbit IgG was used as a secondary reagent.

    Lane 1: HEK-293T whole cell extract (Input). 
    Lane 2: Control IgG instead of ab229683 in HEK-293T whole cell extract. 
    Lane 3: ab229683 IP in HEK-293T whole cell extract.
