| Species | Cynomolgus | ||||
| Protein Construction |
|
||||
| Purity | > 95% as determined by BisTris PAGE | ||||
| Endotoxin Level | Less than 1EU per μg by the LAL method. | ||||
| Biological Activity | Measured by its binding ability in a functional ELISA.Test result was comparable to standard batch. | ||||
| Expression System | HEK293 | ||||
| Theoretical Molecular Weight | 14.4 kDa | ||||
| Apparent Molecular Weight | Due to glycosylation, the protein migrates to 25-30 kDa based on Bis-Tris PAGE result. | ||||
| Formulation | Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). | ||||
| Reconstitution | Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. | ||||
| Storage & Stability | Upon receiving, the product remains stable for 6 months at -20℃ or below. Upon reconstitution, the product should be stable for 3 months at -80℃. Avoid repeated freeze-thaw cycles. |

| Target Background | 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. |
