Specifications
| Synonyms | T-cell replacing factor; IL-5;Interleukin-5; EDF |
| Source | Biotinylated Human IL-5 Protein is expressed from HEK293 with His tag and Avi tag at the N-Terminus. It contains Ile20-Ser134.[Accession | P05113] |
| Molecular Weight | The protein has a predicted MW of 16.1 kDa. Due to glycosylation, the protein migrates to 18-25 kDa based on SDS-PAGE result. |
| Purity | > 95% as determined by SDS-PAGE and HPLC. |
| Formulation | Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. |
| Endotoxin | Less than 1EU per μg by the LAL method. |
| Reconstitution | Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. |
| Activity | ELISA Data: Immobilized Human IL-5 R alpha, hFc Tag at 2μg/ml (100μl/Well) on the plate. Dose response curve for Biotinylated Human IL-5, His Tag with the EC50 of 90.4ng/ml determined by ELISA . |
