Our Abpromise guarantee covers the use of ab234258 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use at an assay dependent concentration. Detects a band of approximately 80, 140 kDa (predicted molecular weight: 98 kDa).


  • 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.

    Developed using the ECL technique.

    Predicted band size: 98 kDa
    Observed band size: 140,80 kDa
    why is the actual band size different from the predicted?

    Exposure time: 29 seconds

    Blocking/Dilution buffer: 5% NFDM/TBST.

    Negative control: Jurkat
    The 140 kDa band corresponds to the full-length Axl, while the 80 kDa band could be the cleaved form of Axl (PMID: 7822279 and 19541935).

    The apparent molecular mass is higher than predicted, likely due to glycosylation (PMID: 23629654).

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab215205).
