  • Function
    May function as a signal transducer between specific cell types of mesodermal origin. In case of filovirus infection, seems to function as a cell entry factor.
  • Tissue specificity
    Highly expressed in metastatic colon tumors. Expressed in primary colon tumors. Weakly expressed in normal colon tissue.
  • Sequence similarities
    Belongs to the protein kinase superfamily. Tyr protein kinase family. AXL/UFO subfamily.
    Contains 2 fibronectin type-III domains.
    Contains 2 Ig-like C2-type (immunoglobulin-like) domains.
    Contains 1 protein kinase domain.

Anti-Axl antibody images

  • Anti-Axl antibody (ab37861) + SKBR3 cell lysate

    HRP-conjugated anti-rabbit IgG
    Developed using the ECL technique

    Observed band size : 97 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 25 kDa. We are unsure as to the identity of these extra bands.
  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human breast cancer (BC) tissue labelling Axl with ab37861. A peroxidase-conjugated anti-rabbit IgG was used as the secondary antibody, followed by AEC staining.

  • ab37861 staining Axl in human breast tumor by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with paraformaldehyde, permeabilized with Tween20 and blocked with 10% serum for 30 minutes at 25°C. Samples were incubated with the primary antibody (in PBS + 10% serum) for 12 hours at 4°C. An undiluted Alexa Fluor® 594-conjugated goat anti-rabbit IgG monoclonal was used as the secondary antibody.

  • ICC/IF image of ab37861 stained SW480 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab37861 at 5µg/ml overnight at +4°C. The secondary antibody (pseudo-colored green) was Alexa Fluor® 488 goat anti- rabbit (ab150081) IgG (H+L) preadsorbed, used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (pseudo-colored red) at a 1/200 dilution for 1h at room temperature. DAPI was used to stain the cell nuclei (pseudo-colored blue) at a concentration of 1.43µM for 1hour at room temperature.

  • Flow cytometry analysis of WiDr cells labelling Axl (green) with ab37861 compared to a negative control (blue). A FITC-conjugated goat anti-rabbit IgG was used as the secondary antibody.
