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, Human/Cynomolgus/Rhesus macaque, Recombinant (His & Avi), Biotinylated is expressed in HEK293 mammalian cells with N-His-Avi tag. The predicted molecular weight is 18.2 kDa and the accession number is P10747.

別名 | CD28 antigen (Tp44), CD28 molecule, CD28, MGC138290 |
Construction | Asn19-Pro152 |
Protein Purity | > 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC |
分子量 | 18.2 kDa (predicted). Due to glycosylation, the protein migrates to 38-50 kDa based on Tris-Bis PAGE result. |
Endotoxin | < 1 EU/μg 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℃. For reconstituted proteinsolutions, 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 shipping with blue ice. |
