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. |
|
Endotoxin |
Less than 1EU per μg by the LAL method. |
|
Purity |
> 95% as determined by SDS-PAGE and HPLC. |
|
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 . |
|
Formulation |
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. |
|
Reconstitution |
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. |
