    This data was developed using the same antibody clone in a different buffer formulation (ab254301).

    Lanes 1-4: Merged signal (red and green). Green - ab254301 observed at 125 kDa. Red - loading control ab8245 observed at 36 kDa.

     ab254301 Anti-Eph receptor B4/HTK antibody [EPR23222-24] 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. ab254301 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.

    Immunohistochemical analysis of paraffin-embedded Human breast cancer tissue labeling Eph receptor B4 with ab254301 at 1/1000 dilution (0.545ug/ml) followed by a Rabbit specific IHC polymer detection kit HRP/DAB (ab209101) at a ready to use dilution. Mainly membranous staining in cancer cells of human breast cancer (PMID: 16816380) is observed. The section was incubated with ab255611 for 30 mins at room temperature. The immunostaining was performed on a Leica Biosystems BOND® RX instrument. Counterstained with Hematoxylin.

    Secondary antibody only control: Secondary antibody is Rabbit specific IHC polymer detection kit HRP/DAB (ab209101) at Ready to use dilution.

    Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0, epitope retrieval solution 2) for 20 mins.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab254301).
