Description
Specifications
Source |
Recombinant Human Fc epsilon RI alpha/FCER1a Protein is expressed from HEK293 with His tag at the C-terminal. It contains Val26-Gln205.[uniprot | P12319-1] |
Molecular Weight |
The protein has a predicted MW of 22.1 kDa. Due to glycosylation, the protein migrates to 48-65 kDa based on Tris-Bis PAGE result. |
Endotoxin |
Less than 1EU per μg by the LAL method. |
Purity |
> 95% as determined by Tris-Bis PAGE and HPLC |
Activity |
ELISA Data: Immobilized Human Fc epsilon RI alpha, His Tag at 0.2μg/ml (100μl/well) on the plate. Dose response curve for Anti-Fc epsilon RI alpha Antibody , hFc Tag with the EC50 of 14.1ng/ml determined by ELISA. |
Formulation |
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. |
Reconstitution |
Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. |
Storage
The product should be stored at -25~-15℃ for 1 year from date of receipt.
2-7 days, 2 ~8 °C under sterile conditions after reconstitution.
3 months, -25~-15℃ under sterile conditions after reconstitution.
Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.
