Active Recombinant Human IL4R Protein, His & Avi-tagged, Biotinylated

Specification :
| Source : HEK293 | Species : Human | Tag : His & Avi | Predicted N Terminal : Met 26 | Form : Lyophilized from sterile PBS, pH7.4, 10% trehalose. | Bio-activity : Measured by its binding ability in a functional ELISA. Immobilized Human IL-4, Tag Free at 5μg/mL (100 μL/well) can bind Biotinylated Human IL-4 R alpha, His Tag with a linear range of 0.005-0.078 μg/mL. | Molecular Mass : Recombinant Human IL4R Protein has a calculated MW of 26.9 kDa. The protein migrates as 40-53 kDa on a SDS-PAGE gel under reducing (R) condition due to glycosylation. | Protein length : Met 26 – His 232 | Endotoxin : Less than 1.0 EU per μg by the LAL method. | Purity : >95% as determined by SDS-PAGE. | Stability : Samples are stable for up to twelve months from date of receipt at -70ºC. | Storage : Store it under sterile conditions at -20ºC~-70ºC. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles. | Reconstitution : It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4℃ before opening to recover the entire contents.
