| 产品编号 | KMP2893 |
|---|---|
| 产品名称 | Human CD28 Protein, hFc Tag, Avi Tag |
| 产品描述 | The Human CD28 Protein(KMP2893) is produced in HEK293 Cells. The target gene encoding the human CD28 (NP_006130.1) (Met1-Pro152) is expressed with a C-terminal Fc region of human IgG1 tag followed by an Avi tag. The expressed protein is biotinylated in vivo by the Biotin-Protein ligase (BirA enzyme) which is co-expressed. |

| 产品背景 | CD28 (Cluster of Differentiation 28) is a disulphide-bonded glycoprotein belonging to the immunoglobulin (Ig) superfamily, and structurally consists of a single Ig V-like extracellular domain, a transmembrane domain and an intracellular domain. Mouse CD28 is constitutively expressed on the surface of all murine T cells and on developing thymocytes as disulfide-linked homodimers or as monomers. CD28 can binds the B7-1 and B7-2 ligand, and together perform important functions in the T and B cell response pathways. B7/CD28 family members, which can augment or antagonize T-cell receptor signaling, in the regulation of central and peripheral T-cell tolerance. CD28 is thus involved in T-cell activation, the induction of cell proliferation and cytokine production and promotion of T-cell survival. |
