Product Description |
Recombinant Human PD-L2/B7-DC Protein is expressed from HEK293 with hFc tag at the C-terminus.It contains Leu20-Thr220. |
Product Background |
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. |

> 95% as determined by Bis-Tris PAGE |
Endotoxin |
Less than 1EU per ug by the LAL method. |
Form |
Lyophilized |
Shipping |
Shipped at ambient temperature. |
Formulation |
Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. |
Reconstitution |
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water. |
Stability And Storage |
Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles. |
