Recombinant Human Siglec-3/CD33 Protein is expressed from Expi293 with His tag and Avi tag at the C-terminal. It contains Asp18-His259.[Accession | P20138-1] |
分子量大小(Molecular Weight)
|
The protein has a predicted MW of 29.6 kDa. Due to glycosylation, the protein migrates to 52-60 kDa based on Tris-Bis PAGE result. |
内毒素(Endotoxin)
|
Less than 1EU per μg by the LAL method. |
纯度(Purity)
|
> 95% as determined by Tris-Bis PAGE |
制剂(Formulation)
|
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. |
重构方法(Reconstitution)
|
Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/ml is recommended (usually we use 1mg/ml solution for lyophilization). Dissolve the lyophilized protein in distilled water. |
存储(Storage)
|
-20 to -80°C for 12 months as supplied from date of receipt. |

-20 to -80°C for 3-6 months in unopened state after reconstitution.
2-8°C for 2-7 days after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please avoid freeze-thaw cycles.
Sialic-acid-binding immunoglobulin-like lectin (Siglec) that plays a role in mediating cell-cell interactions and in maintaining immune cells in a resting state.They are sialoadhesin/CD169/Siglec-1, CD22/Siglec-2, CD33/Siglec-3, Myelin-Associated Glycoprotein (MAG/Siglec-4a) and Siglecs 5 to 11. To date, no Siglec has been shown to recognized any cell surface ligand other than sialic acids, suggesting that interactions with glycans containing this carbohydrate are important in mediating the biological functions of Siglecs.
