< 1.0 EU per μg of the protein as determined by the LAL method
Activity
Measured by its binding ability in a functional ELISA. Immobilized human EFNB2 at 2 μg/ml (100 μl/well) can bind human EphB4 with a linear range of 1.56-12.5 ng/ml.
Protein Construction
A DNA sequence encoding the human EFNB2 (NP_004084.1) extracellular domain (Met 1-Ala 229) was expressed, fused with a C-terminal polyhistidine tag.
Accession#
NP_004084.1
Expressed Host
HEK293 Cells
Species
Human
Predicted N Terminal
Ile 28
Molecule Mass
The recombinant human EFNB2 consists of 213 amino acids after removal of the signal peptide and predicts a molecular mass of 23.6 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh EFNB2 is approximately 35-40 kDa due to glycosylation.
Formulation
Lyophilized from sterile PBS, pH 7.4Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Shipping
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.
Stability & Storage
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution
A hardcopy of datasheet with reconstitution instructions is sent along with the products. Please refer to it for detailed information.
