Recombinant Human EPOR Protein (Ala25-Pro250), C-hFc-tagged
Product Description
Cat
IMP-9979
Official Symbol
EPOR
Product Overview
Recombinant human Erythropoietin R protein (Ala25-Pro250) with a Human IgG1 (Pro100-Lys330)Fc tag at C-terminus was expressed in Mouse myeloma cell line.
Description
This gene encodes the erythropoietin receptor which is a member of the cytokine receptor family. Upon erythropoietin binding, this receptor activates Jak2 tyrosine kinase which activates different intracellular pathways including: Ras/MAP kinase, phosphatidylinositol 3-kinase and STAT transcription factors. The stimulated erythropoietin receptor appears to have a role in erythroid cell survival. Defects in the erythropoietin receptor may produce erythroleukemia and familial erythrocytosis. Dysregulation of this gene may affect the growth of certain tumors. Alternate splicing results in multiple transcript variants.
Expression System
Mouse myeloma cell line
Species
Human
Tag
C-hFc
Form
Lyophilized from a 0.2 μm filtered solution in PBS, EDTA and CHAPS.
Molecular Mass
Predicted Molecular Mass: 51.4 kDa (monomer)
SDS-PAGE: 55-60 kDa, reducing conditions
Protein length
Ala25-Pro250
Bio-activity
Measured by its ability to inhibit Epo-dependent proliferation of TF-1 human erythroleukemic cells. The ED50 for this effect is 1-4 ng/mL in the presence of 0.1 U/mL of recombinant human Epo.
Endotoxin
<0.10 EU/μg of the protein by the LAL method.
Purity
>90%, by SDS-PAGE under reducing conditions and visualized by silver stain.
Notes
Disulfide-linked homodimer
Storage
Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
12 months from date of receipt, -20 to -70 centigrade as supplied.
1 month, 2 to 8 centigrade under sterile conditions after reconstitution.
3 months, -20 to -70 centigrade under sterile conditions after reconstitution.
Reconstitution
