Human Axl Protein, His Tag (SPR verified)
Synonym
AXL, UFO
Source
Human Axl, His Tag (AXL-H5226) is expressed from human 293 cells (HEK293). It contains AA Ala 26 - Pro 449 (Accession # AAH32229).
Predicted N-terminus: Ala 26
Molecular Characterization

This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 46.6 kDa. The protein migrates as 60-70 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Endotoxin
Less than 1.0 EU per μg by the LAL method / rFC method.
Purity
>95% as determined by SDS-PAGE.
Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

Background
AXL Receptor Tyrosine Kinase is also known as Tyrosine-protein kinase receptor UFO, which belongs to the protein kinase superfamily, Tyr protein kinase family and AXL/UFO subfamily. AXL contains two fibronectin type-III domains, two Ig-like C2-type (immunoglobulin-like) domains and one protein kinase domain. AXL is highly expressed in metastatic colon tumors. AXL is activated by GAS6-binding and subsequent autophosphorylation. AXL is involved in signal transduction from the extracellular matrix into the cytoplasm by binding growth factors, and thus implicated in the stimulation of cell proliferation.
