All lanes : Anti-Eph receptor B4/HTK antibody [EPR23221-54] (ab254300) at 1/1000 dilution
Lane 1 : Wild-type HEK293T cell lysate
Lane 2 : EPHB4 knockout HEK293T cell lysate
Lane 3 : MCF7 cell lysate
Lane 4 : HT-29 cell lysate
Lysates/proteins at 20 µg per lane.
Secondary
All lanes : Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) at 1/10000 dilution
Predicted band size: 108 kDa
Observed band size: 125 kDa why is the actual band size different from the predicted?This data was developed using the same antibody clone in a different buffer formulation (ab254300).
Lanes 1-4: Merged signal (red and green). Green - ab254300 observed at 125 kDa. Red - loading control ab8245 observed at 36 kDa.
ab254300 Anti-Eph receptor B4/HTK antibody [EPR23221-54] was shown to specifically react with Eph receptor B4/HTK in wild-type HEK293T cells. Loss of signal was observed when knockout cell line ab266733 (knockout cell lysate ab257429) was used. Wild-type and Eph receptor B4/HTK knockout samples were subjected to SDS-PAGE. ab254300 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4°C at 1 in 1000 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.

Immunoprecipitation - Anti-Eph receptor B4/HTK antibody [EPR23221-54] - BSA and Azide free (ab269867)
Eph receptor B4 was immunoprecipitated from 0.35 mg HUVEC (human umbilical vein endothelial cell) whole cell lysate with ab254300 at 1/30 dilution (2ug in 0.35mg lysates). Western blot was performed on the immunoprecipitate using ab254300 at 1/500 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366) was used at 1/1000 dilution.
Lane 1: HUVEC (human umbilical vein endothelial cell) whole cell lysate 10ug
Lane 2: ab254300 IP in HUVEC whole cell lysate
Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab254300 in HUVEC whole cell lysate
Blocking and dilution buffer and concentration: 5% NFDM/TBST.
Exposure time: 8 seconds.
Cleaved intracellular domain (ICD) was observed at around 47kDa. (PMID: 24854540).
This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab254300).
