EphB6 Protein, Human, Recombinant

Ephrins are divided into the ephrin-A (EFNA) class and the ephrin-B (EFNB) class based on their structures and sequence relationships. Ephrin receptors make up the largest subgroup of the receptor tyrosine kinase (RTK) family. EphB6 is an unusual Eph receptor, lacking catalytic capacity due to alterations in its kinase domain. Interestingly, increased metastatic activity is associated with reduced EphB6 receptor expression in several tumor types, including breast cancer. This emphasizes the potential of EphB6 to act as a suppressor of cancer aggressiveness. EphB6 suppress cancer invasiveness through c-Cbl-dependent signaling, morphologic changes, and cell attachment and indicate that EphB6 may represent a useful prognostic marker and a promising target for therapeutic approaches. EphB6 can both positively and negatively regulate cell adhesion and migration, and suggest that tyrosine phosphorylation of the receptor by an Src family kinase acts as the molecular switch for the functional transition. In addition, Ephrin-B2 may be a physiological ligand for the EphB6 receptor.

The mature form of human EphB6 (NP_004436.1) extracellular domain (Met 1-Ser 579) with quinary-aa peptide (DDDDK) at the C-terminus was expressed and purified.

Measured by its binding ability in a functional ELISA.Immobilized human EphB6 (Cat:PH51488M0) at 10 μg/mL (100 μl/well) can bind biotinylated human EFNB2-Fch (Cat:10881-H03H) with a linear range of 1.56-50 ng/mL.

Lyophilized from sterile 100mM NaCl, 50mM Tris, pH 7.5 Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.

The recombinant mature human EphB6 consists of 569 amino acids and has a calculated molecular mass of 60.4 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rhEphB6 is approximately 72 kDa due to glycosylation.

In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise. Stable for 1 year at -20°C or below from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and opening the cap. For long-term storage, aliquot and store at -20°C or below. Avoid repeated freeze-thaw cycles.
