Biotinylated Human Fc gamma RI/CD64 Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Biotinylated Human Fc gamma RI/CD64 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. It contains Gln16-Pro288.[Accession | P12314-1]

分子量大小(Molecular Weight)

The protein has a predicted MW of 33.5 kDa. Due to glycosylation, the protein migrates to 55-68 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)

Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.

重构方法(Reconstitution)

Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.

存储(Storage)

-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.

产品数据(Assay Data)
Tris-Bis PAGE

Biotinylated Human Fc gamma RI on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.

SEC-HPLC

The purity of Biotinylated Human Fc gamma RI is greater than 95% as determined by SEC-HPLC.

SPR Data

Biotinylated Human Fc gamma RI, His-Avi Tag captured on CM5 Chip via Anti-His Antibody can bind Trastuzumab with an affinity constant of 0.91 nM as determined in SPR assay (Biacore T200).

背景(Background)

The Fc gamma Rs have been divided into three classes based on close relationships in their extracellular domains; these groups are designated Fc gamma  RI (also known as CD64), Fc gamma  RII (CD32), and Fc gamma  RIII (CD16). Each group may be encoded by multiple genes and exist in different isoforms depending on species and cell type.

分子别名(Synonyms)

CD64; CD64a; Fc gamma RI; FCG1; Fc-gamma RIA; FCGR1; FcgRI; FCRI; FcRIA; FLJ18345; FCGR1A; IGFR1; Fcr; Fcgr; FCE1A; FcERI

Note: HPLC results always come from liquid protein, due to absorption peak interference of trehalose in lypholized powder.
