Product Description
Specifications
| Size | 10 µg, 50 µg, 200 µg |
| Estimated Lead Time | 2-3 business days |
| Species | Human |
| Accession Number | P16410-1 |
| Gene Id | 1493 |
| Gene Symbols | CD152, CTLA4 |
| Protein Name / Synonyms | Cytotoxic T-lymphocyte protein 4 (Cytotoxic T-lymphocyte-associated antigen 4) (CTLA-4) (CD antigen CD152) |
| Expressed Region | Lys36-Asp161 |
| Expression System | HEK293 cells |
| Conjugation | Biotin |
| Tag | N-terminal histidine tag. The primary amino groups (-NH2) at the N-terminus and the side chains of lysine (K) residues were biotin-conjugated using the standard chemical labeling method. |
| Purity | >95% |
| Purity Determined By | SDS-PAGE under reducing conditions and visualized by Coomassie blue staining |
| Molecular Weight (kDa) | Recombinant protein has a calculated molecular weight of about 14 kDa. Due to the abundant glycosylation, it migrates as approximately 18-22 kDa protein bands in SDS-PAGE under DTT, beta-mercaptoethanol reducing conditions. |
| Format | Lyophilized powder |
| Formulation | Lyophilized from a 0.2 µm filtered solution in PBS |
| Concentration (lot specific) | Determined by Pierce BCA protein assay kit |
| Preservative | None |
| Reconstitution | Briefly spin the vial and bring the contents to the bottom prior to opening. It is recommended to reconstitute at 0.5 - 1 mg/mL with sterile deionized water. |
| Endotoxin Level | Not determined |
| Research Area | Inflammation, Autoimmune Disease, Cancer Immunology |
| Shipping Type | Ambient temperature |
| Storage | -20°C |

Storage/Stability
Upon arrival, the lyophilized protein may be stored for 2 weeks at 4°C. For long term storage, it is recommended to store desiccated below -20°C in a manual defrost freezer. Following reconstitution, the protein may be stored for 2 weeks under sterile conditions at -20°C. For long term storage, it is recommended to make appropriate aliquots and store at -80°C. Avoid repeated freeze-thaw cycles.
