  • All lanes : Anti-PTPN12 antibody (ab76939) at 0.04 µg/ml

    Lane 1 : Whole cell HeLa lysate at 50 µg
    Lane 2 : Whole cell HeLa lysate at 15 µg
    Lane 3 : Whole cell HeLa lysate at 5 µg

    Developed using the ECL technique

    Predicted band size : 88 kDa
    Observed band size : 118 kDa (why is the actual band size different from the predicted?)

    Exposure time : 30 seconds
  • Lane 1: ab76939, at 1 µg/mg, staining PTPN12 in HeLa whole cell lysate by Western blot of immunoprecipitate (1 mg of lysate for IP, 20% of IP loaded). Immunoprecipitation was performed by using ab76939 at 3µg/mg of lysate.
    Lane 2: Control IgG.
    Detection: Chemiluminescence with an exposure time of 3 seconds.
