Human Siglec-3/CD33 Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Human Siglec-3/CD33 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. 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
> 95% as determined by HPLC

制剂(Formulation)

Supplied as 0.22μm filtered solution in 20mM PB, 500mM NaCl (pH 8.0).

存储(Storage)

Valid for 12 months from date of receipt when stored at -80°C.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

产品数据(Assay Data)
Tris-Bis PAGE

Human Siglec-3 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.

SEC-HPLC

The purity of Human Siglec-3 is greater than 95% as determined by SEC-HPLC.

ELISA Data

Immobilized Human Siglec-3, His Tag at 0.5μg/ml (100μl/Well) on the plate. Dose response curve for Anti-Siglec-3 Antibody, hFc Tag with the EC50 of 3.1ng/ml determined by ELISA.

背景(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.

分子别名(Synonyms)

CD33 molecule; CD33; FLJ00391; gp67; Siglec3; Siglec-3; p67
