Name : Cynomolgus Siglec-3/CD33 Protein
Product Source :
Recombinant Cynomolgus Siglec-3/CD33 Protein is expressed from HEK293 with His tag at the C-Terminus. It contains Ser17-Leu248.[Accession | XP_005590138.1]
Molecular Weight :
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.
Endotoxin Level :
Less than 1EU per μg by the LAL method.
Purity :
> 95% as determined by Tris-Bis PAGE> 95% as determined by HPLC
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.
Storage and Stability :
-20 to -80°C for 12 months as supplied from date of receipt.-80°C for 3-6 months after reconstitution.2-8°C for 2-7 days after reconstitution.Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Product Concentration :
Tris-Bis PAGE Cynomolgus Siglec-3 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. SEC-HPLC The purity of Cynomolgus Siglec-3 is greater than 95% as determined by SEC-HPLC.
Background :
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.
Synonyms :
CD33 molecule; CD33; FLJ00391; gp67; Siglec3; Siglec-3; p67
