| 来源 | The recombinant Canine CD28 Protein, (amino acids Thr18-Pro153) fused with a His tag at the C-terminus, was produced in HEK 293 cells. |
| Accession | Q9GKP3 |
| 产品标签 | C-His |
| 生物素化 | no |
| 确定序列 | Thr18-Pro153 |
| 分子量 | The recombinant Canine CD28 protein with the His tag at the C-terminus has a predicted MW of 16.7 kDa. Due to glycosylation, the protein migrates to 40-60 kDa based on Tris-Bis PAGE result. |
| Form | Lyophilized |
| 形式 | Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. |
| 制剂 | It is recommended to reconstitute the lyophilized recombinant Canine CD28 Protein in sterile H2O to a protein concentration not less than 100 ug/ml. Centrifuge the tube before opening. |
| 纯度 | >95% by SEC-HPLC and SDS-PAGE under reducing conditions. |
| 内毒素 | Less than 1 EU per ug of protein as determined by LAL method. |
| 运输 | The recombinant Canine CD28 Protein is shipped with ice pack. Upon receipt, store it immediately at the temperature recommended below. |
| 稳定性与储存 | Use a manual defrost freezer and avoid repeated freeze-thaw cycles. 12 months from date of receipt, -20 to -70°C as supplied. 1 week, 2 to 8°C under sterile conditions after reconstitution. 6 months, -20 to -70°C under sterile conditions after reconstitution. |
| 注意事项 | Conditions of optimal recombinant Canine CD28 Protein performance should be determined experimentally by the investigator. |

BP004767: Canine CD28 Protein with the C-His Tag (犬 CD28 蛋白 C-His 标签)
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.
