Recombinant Cynomolgus CTLA-4/CD152 Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Ala37-Ser160 [Accession | G7PL88-1]. |
分子量大小(Molecular Weight)
|
The protein has a predicted MW of 14.4 kDa. Due to glycosylation, the protein migrates to 25-30 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. |

CTLA-4 (cytotoxic T-lymphocyte-associated protein 4), also known as CD152, is a protein receptor that, functioning as an immune checkpoint, downregulates immune responses.CTLA4 is constitutively expressed in regulatory T cells but only upregulated in conventional T cells after activation – a phenomenon which is particularly notable in cancers. It acts as an "off" switch when bound to CD80 or CD86 on the surface of antigen-presenting cells.
