  • LAG-3 was immunoprecipitated from 0.5 mg HDLM-2 whole cell lysate with ab243884 at 12 µl per reaction. Western blot was performed on the immunoprecipitate using ab243884 at 1/1000 dilution.

    Lane 1: ab243884 IP in HDLM-2 whole cell lysate.

    Lane 2: Control IgG IP in HDLM-2 whole cell lysate.

    Detection: Chemiluminescence with an exposure time of 10 seconds.

  • Western blot analysis using ab243884 at 1/1000 dilution.

    Lane 1: HDLM-2 whole cell lysate (50 µg).

    Lane 2: RPMI 8226 whole cell lysate (50 µg).
