Western blot - Anti-CD105 antibody [EPR19911] - BSA and Azide free (ab251457)All lanes : Anti-CD105 antibody [EPR19911] (ab206419) at 1/1000 dilution
Lane 1 : Wild-type HeLa whole cell lysate
Lane 2 : CD105 knockout HeLa whole cell lysate
Lysates/proteins at 20 µg per lane.
Predicted band size: 70 kDaThis data was developed using ab206419, the same antibody clone in a different buffer formulation.
Lanes 1 - 2: Merged signal (red and green). Green - ab206419 observed at 70 kDa. Red - loading control, ab8245, observed at 37 kDa.
ab206419 was shown to recognize CD105 in wild-type HeLa cells as signal was lost at the expected MW in CD105 knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and CD105 knockout samples were subjected to SDS-PAGE. The membrane was blocked with 3% Milk. ab206419 and ab8245 (Mouse anti-GAPDH loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.

Lane 3 : Human fetal kidney tissue lysate
Lysates/proteins at 10 µg per lane.
Secondary
Lanes 1-2 : Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/100000 dilution
Lane 3 : Goat Anti-Rabbit IgG Peroxidase Conjugate, specific to the non-reduced form of IgG at 1/10000 dilution
Predicted band size: 70 kDa
Observed band size: 90,95 kDa why is the actual band size different from the predicted?
Exposure time: 3 minutesThis data was developed using ab206419, the same antibody clone in a different buffer formulation.
Blocking and dilution buffer: 5% NFDM/TBST.
The molecular weight observed is consistent with what has been described in the literature (PMID: 1692830, 18223685, 11164421).
