Product Description |
Recombinant Human ITPRIPL1/CD3L1 Protein is expressed from HEK293 with hFc tag at the C-terminus.It contains His25-Gly103. |
Product Background |
Inositol 1,4,5-trisphosphate receptor-interacting protein-like 1 (ITPRIPL1), a single-pass type I membrane protein with uncharacterized functions, exhibits normal testis-enriched expression and widespread overexpression in various human cancers. ITPRIPL1 possesses a distinct ECD and is particularly prevalent in tumors exhibiting low or no PD-L1 expression. ITPRIPL1 functions as an inhibitory ligand of CD3ε, and its expression inhibits T cells in the tumor microenvironment. |

> 95% as determined by Bis-Tris PAGE;> 95% as determined by HPLC |
Endotoxin |
Less than 1 EU 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 |
Dissolve the lyophilized protein in distilled water. It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 ug or less, at 1mg/ml for 500ug or 1mg lyophilized powder. Do not mix by vortex or vigorous shaking. |
Stability And Storage |
-20 to -80°C for 12 months as supplied from date of receipt.；-80°C for 3 months after reconstitution.；Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles. |
