Human GAS6 (49-678) Protein, His Tag
Synonym
GAS6, GAS-6, AXLLG
Source
Human GAS6 Protein, His Tag (GA6-H5246) is expressed from human 293 cells (HEK293). It contains AA Ala 49 - Ala 678 (Accession # Q14393-2).
Molecular Characterization
This protein carries a polyhistidine tag at the N-terminus.
The protein has a calculated MW of 71.8 kDa. The protein migrates as 80 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
Endotoxin
Less than 1.0 EU per μg by the LAL method / rFC method.
Purity
>90% as determined by SDS-PAGE.
Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

Background
GAS6 (Growth arrest-specific protein 6) is also known as AXL receptor tyrosine kinase ligand, AXLLG. Ligand for tyrosine-protein kinase receptors AXL, TYRO3 and MER whose signaling is implicated in cell growth and survival, cell adhesion and cell migration. GAS6/AXL signaling plays a role in various processes such as endothelial cell survival during acidification by preventing apoptosis, optimal cytokine signaling during human natural killer cell development, hepatic regeneration, gonadotropin-releasing hormone neuron survival and migration, platelet activation, or regulation of thrombotic responses.
