Specifications
Source |
Recombinant Human Siglec-8 Protein is expressed from HEK293 with hFc tag at the C-terminal. It contains Met17-Ala363.[Uniprot | Q9NYZ4] |
Molecular Weight |
The protein has a predicted MW of 64.6 kDa. Due to glycosylation, the protein migrates to 70-82 kDa based on Tris-Bis PAGE result. |
Endotoxin |
Less than 1EU per μg by the LAL method. |
Purity |
> 95% as determined by Tris-Bis PAGEand HPLC |
Formulation |
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 5% 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. |
