Recombinant Human CD40/TNFRSF5 Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Glu21-Arg193 [Accession | P25942-1]. |
分子量大小(Molecular Weight)
|
The protein has a predicted MW of 20 kDa. Due to glycosylation, the protein migrates to 35-40 kDa based on Bis-Tris PAGE result. |
纯度(Purity)
|
> 95% as determined by Bis-Tris PAGE |
内毒素(Endotoxin)
|
Less than 1EU per μg by the LAL method. |
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. |

Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
CD40 is a costimulatory protein found on antigen presenting cells and is required for their activation. The binding of CD154 (CD40L) on TH cells to CD40 activates antigen presenting cells and induces a variety of downstream effects.CD40 molecule is a potential target for cancer immunotherapy. There are number of completed and ongoing clinical trials where agonistic anti-CD40 monoclonal antibodies are employed to activate an anti-tumor T cell response via activation of dendritic cells.
