| Scientific Background | 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. |
| Molecular Mass | The protein has a predicted MW of 42.6 kDa. Due to glycosylation, the protein migrates to 55-70 kDa based on Bis-Tris PAGE result. |
| Sl Sequence | Asn19-Pro152 |
| Solubility | Dissolve the lyophilized protein in distilled water. It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 μg or less, at 1mg/ml for 500μg or 1mg lyophilized powder. Do not mix by vortex or vigorous shaking. |
| Appearance | Lyophilized |
| Endotoxin Levels | Less than 1 EU per μg by the LAL method. |
| Expression System | HEK293 |
| Gene Id | P10747-1 |
| Amino Acid Sequence | Recombinant Human/Cynomolgus/Rhesus macaque CD28 Protein is expressed from HEK293 with hFc (IgG1) tag and Flag tag at the N-Terminus.It contains Asn19-Pro152. |
| Storage | -20 to -80°C for 12 months as supplied from date of receipt.；-80°C for 3 months after reconstitution.；Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles. |
