CVRARTR
Based on 1 Customer Validation
CVRARTR is a programmed cell death ligand-1 (PD-L1) antagonist with a KD of 281 nM. CVRARTR induces the internalization of PD-L1 and downregulates PD-L1 on the cell surface. CVRARTR restores cytokine secretion and T cell proliferation in cell CT26. CVRARTR exhibits antitumor efficacy against in CT26 homograft mouse model. CVRARTR can be used in melanoma research.

Description
In Vitro
CVRARTR (25 μM) has a stronger binding ability to MDA-MB231 cells with high PD-L1 expression than to MCF7 cells with low PD-L1 expression[1].
CVRARTR can increase the secretion of cytokines IFN-γ, TNF-α, and granzyme B, promote T cell proliferation, and enhance tumor cell lysis in T cells co-cultured with B16F10-OVA melanoma cells[1].
CVRARTR (24 h) promotes the proliferation of T lymphocytes co-cultured with 4T1 cells[2].

Solvent & Solubility
In Vitro:
DMSO : 6.25 mg/mL (7.26 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

In Vivo:
Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 0.62 mg/mL (0.72 mM); Clear solution
This protocol yields a clear solution of ≥ 0.62 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (6.2 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 0.62 mg/mL (0.72 mM); Clear solution
This protocol yields a clear solution of ≥ 0.62 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (6.2 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
