Human HVEM/TNFRSF14 Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Human HVEM/TNFRSF14 Protein is expressed from Expi293 with His tag at the C-terminal. It contains Leu39-Val202.[Accession | Q92956-1]

分子量大小(Molecular Weight)

The protein has a predicted MW of 18.5 kDa. Due to glycosylation, the protein migrates to 32-48 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 tubes 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.
-20 to -80°C for 3-6 months in unopened state after reconstitution.
2-8°C for 2-7 days after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please avoid freeze-thaw cycles.

背景(Background)

Herpesvirus entry mediator (HVEM), also known as tumor necrosis factor receptor superfamily member 14 (TNFRSF14), is a human cell surface receptor of the TNF-receptor superfamily.  Two TNF superfamily ligands lymphotoxin α (TNF-β) and LIGHT (TNFSF14) are identified as cellular ligands for HVEM and initiate the positive signaling.

分子别名(Synonyms)

CD270; CD40-like protein;  HVEM; LIGHTR; ATAR; TNFRSF14; TR2
