CD28 Protein, Canine, Recombinant (mFc)
(Synonyms: MGC138290, CD28 molecule, CD28 antigen (Tp44), CD28) Copy Product InfoSynonyms: MGC138290, CD28 molecule, CD28 antigen (Tp44), CD28
Catalog No. TMPK-01177 Copy Product Info
CD28 is the receptor for CD80 (B7-1) and CD86 (B7-2) proteins.When activated by Toll-like receptor ligands, the CD80 expression is upregulated in antigen presenting cells (APCs). The CD86 expression on antigen presenting cells is constitutive. CD28 is the only B7 receptor constitutively expressed on naive T cells. CD28 Protein, Canine, Recombinant (mFc) is expressed in HEK293 mammalian cells with C-mFc tag. The predicted molecular weight is 41.6 kDa and the accession number is Q9GKP3.

| Description | CD28 is the receptor for CD80 (B7-1) and CD86 (B7-2) proteins.When activated by Toll-like receptor ligands, the CD80 expression is upregulated in antigen presenting cells (APCs). The CD86 expression on antigen presenting cells is constitutive. CD28 is the only B7 receptor constitutively expressed on naive T cells.

| Species | Canine |
| Expression System | HEK293 Cells |
| Tag | C-mFc |
| Accession Number | Q9GKP3 |
| Construction | Thr18-Pro153 |
| Protein Purity | > 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC |
| Endotoxin | < 1.0 EU/μg of the protein as determined by the LAL method. |
| Formulation | Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS (pH 7.4). Typically, 8% trehalose is incorporated as a protective agent before lyophilization. |
| Reconstitution | Reconstitute the lyophilized protein in distilled water. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing. |
| Stability & Storage | It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots. |
| Shipping | In general, lyophilized powders are shipped with blue ice, while solutions are shipped with dry ice. |
| Synonyms | MGC138290, CD28 molecule, CD28 antigen (Tp44), CD28 |
| Research Background |
| Molecular Weight | 41.6 kDa (predicted). Due to glycosylation, the protein migrates to 50-70 kDa based on Tris-Bis PAGE result. |
| Storage | Lyophilized powder: -20~-80°C for 1 year | Solution: -80°C for 6 months |
