Cynomolgus Siglec-3/CD33 Protein (CD3-CM133)
|Recombinant Cynomolgus Siglec-3/CD33 Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Ser17-Leu248.
|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.
|The protein has a predicted MW of 26.83 kDa. Due to glycosylation, the protein migrates to 40-50 kDa based on Tris-Bis PAGE result.
|> 95% as determined by Tris-Bis PAGE;> 95% as determined by HPLC
|Less than 1EU per ug by the LAL method.
|Shipped at ambient temperature.
|Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
|Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
|Stability And Storage
|Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
