VIPhyb
Based on 1 Customer Validation
VIPhyb is a vasoactive intestinal polypeptide (VIP) receptor antagonist. VIPhyb can inhibit VIP signaling, increase T-cell immunity and downregulate PD1. VIPhyb can inhibit cancer cell proliferation. VIPhyb can reduce inflammatory cytokine expression. VIPhyb can enhance viral clearance. VIPhyb can be used for the researches of cancer, infection and inflammation and immunology, such as non-small cell lung cancer (NSCLC), cytomegalovirus infection and colitis.

Result:Prolonged survival of mice.
Had less inflammation and tissue damage in the liver.
Decreased intranuclear viral inclusions, inflammatory leukocytes, necrosis, and CMV-infected giant cells.
Increased the numbers of effector/memory CD8+ T-cells and mature NK cells were.
Prevented the up-regulation of PD-L1.
Increased CD80, CD86, and MHC-II expression.
Increased numbers of IFN-γ- and TNF-α-expressing NK cells and T-cells.
Decreased the percentage of Treg cells and levels of serum VEGF.

Solvent & Solubility
DMSO : 100 mg/mL (28.84 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : ≥ 100 mg/mL (28.84 mM)
* "≥" means soluble, but saturation unknown.
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.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.
