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.

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).

Secondary
All lanes : Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/100000 dilution
Predicted band size: 108 kDa
Observed band size: 120 kDa why is the actual band size different from the predicted?Blocking and dilution buffer: 5% NFDM/TBST.
Exposure time: 37 seconds.
Negative control: SW620 (PMID: 19366806).
EphB4 is negative in SW620 and positive in HT29 and HUVEC, which is different from expression profiles of other EphB family members.
Cleaved intracellular domain (ICD) was observed at around 47kDa. (PMID: 24854540).
The expression profile observed is consistent with what has been described in the literature (PMID: 19366806, 16840724).
