BP003820: Human IgE Protein with the C-His-Avi Tag
Source: The recombinant Human IgE Protein, (amino acids Cys209-Lys428) fused with a His-Avi tag at the C-terminus, was produced in HEK 293 cells.
Molecular Weight:The recombinant Human IgE protein with the His-Avi tag at the C-terminus has a predicted MW of 27.8 kDa. Due to glycosylation, the protein migrates to 30-35 kDa based on Tris-Bis PAGE result.
Activity: Immobilized recombinant Human IgE protein with the C-His-Avi tag at 0.5 ug/ml (100 ul/well) on the plate. Dose response curve for the recombinant Anti-IgE Antibody protein with the C-hFc tag with the EC50 of 7.0 ng/ml determined by ELISA.
Purity: >95% by SEC-HPLC and SDS-PAGE under reducing conditions.
Endotoxin Level: Less than 1 EU per ug of protein as determined by LAL method.
Formulation: Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution: It is recommended to reconstitute the lyophilized recombinant Human IgE Protein in sterile H2O to a protein concentration not less than 100 ug/ml. Centrifuge the tube before opening.
Shipping: The recombinant Human IgE Protein is shipped with ice pack. Upon receipt, store it immediately at the temperature recommended below.
Stability & Storage: Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
12 months from date of receipt, -20 to -70°C as supplied.
1 week, 2 to 8°C under sterile conditions after reconstitution.
6 months, -20 to -70°C under sterile conditions after reconstitution.
