蛋白长度：A DNA sequence encoding the human/cynomolgus/rhesus CD28 (P10747-1/Q0PDN3-1/NP_001036106.2) (Asn19-Pro152) was expressed with a polyhistidine tag at the C-terminus and a signal peptide (Q0PDN3-1/NP_001036106.2, Met1-Gly18) at the N-terminus. Human, Cynomolgus and Rhesus CD28 sequences (Asn19-Pro152) are identical.
性质：
表达系统：HEK293 Cells
种属：Human, Cynomolgus, Rhesus
氨基酸序：Asn19-Pro152
标签类型：C-His
分子量：The recombinant human/cynomolgus/rhesus CD28 consists of 145 amino acids and predicts a molecular mass of 16.6 kDa.
活性：At Leading Biology, the biological activity of a recombinant protein is routinely measured using a bioassay, e.g. chemotaxis or cell proliferation assay, enzyme assay, or a functional ELISA. When a recombinant protein is an enzyme, specific activity is derived from an enzymatic assay. Each enzyme is tested for potency by cleavage of a substrate. We are in the process of updating the biological activity data. If you have any questions regarding this update, please feel free to contact our technical support team.
内毒素：< 1.0 EU per μg protein as determined by the LAL method.
基因名称：CD28 molecule
通用名：CD28
蛋白序参考：NP_001036106.2
总结：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.
形式：Lyophilized
纯度：> 90 % as determined by SDS-PAGE.
储存条件：In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise. Stable for 1 year at -20°C or below from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and opening the cap. For long-term storage, aliquot and store at -20°C or below. Avoid repeated freeze-thaw cycles.
储存溶液：Lyophilized from sterile PBS, pH 7.4. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.
