PD-1 ligand 2 (PD-L2) as a second ligand for PD-1 and compare the function and expression of PD-L1 and PD-L2. Engagement of PD-1 by PD-L2 dramatically inhibits T cell receptor (TCR)-mediated proliferation and cytokine production by CD4 T cells. At low antigen concentrations, PD-L2-PD-1 interactions inhibit strong B7-CD28 signals. PD-L2 Protein, Cynomolgus, Recombinant (aa 20-220, His) is expressed in HEK293 mammalian cells with C-His tag. The predicted molecular weight is 23.73 kDa and the accession number is A0A2K5U5Z4.

蛋白构建 | Leu20-Thr220 |
蛋白纯度 | > 95% as determined by Tris-Bis PAGE; > 95% as determined by HPLC |
分子量 | 23.73 kDa (predicted). Due to glycosylation, the protein migrates to 40-50 kDa based on Tris-Bis PAGE result. |
内毒素 | < 1 EU/μg by the LAL method. |
缓冲液 | 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. |
复溶方法 | 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. |
存储 |
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. |
运输方式 |
In general, Lyophilized powders are shipping with blue ice. |
