产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Cynomolgus/Rhesus macaque CD27/TNFRSF7 Protein is expressed from HEK293 with hFc tag at the C-Terminus. It contains Ala20-Arg191.[Accession | XP_005569963.1]

分子量大小(Molecular Weight)

The protein has a predicted MW of 46.5 kDa. Due to glycosylation, the protein migrates to 60-70 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

Cynomolgus/Rhesus macaque CD27 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.

SEC-HPLC

The purity of Cynomolgus/Rhesus macaque CD27 is greater than 95% as determined by SEC-HPLC.

ELISA Data

Immobilized Cynomolgus CD27 Ligand, His Tag at 2μg/ml (100μl/well) on the plate. Dose response curve for Cynomolgus/Rhesus macaque CD27, hFc Tag with the EC50 of 41.3ng/ml determined by ELISA.

背景(Background)

CD27, also known as TNFRSF7, is an approximately 55 kDa transmembrane protein in the TNF receptor superfamily. It functions as a co‑stimulatory molecule that supports lymphocyte activation and survival. It binds to ligand CD70, and plays a key role in regulating B-cell activation and immunoglobulin synthesis.

分子别名(Synonyms)

CD27 antigen; Tp55; TNFRSF7; S152; T14; S152. LPFS2; MGC20393; S152CD27L receptor

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