Product Introduction

Bioactivity

Description	Tetrahydrobiopterin (BH4) is a cofactor for aromatic amino acid hydroxylases and an essential cofactor for nitric oxide synthase (NOS), which is used in the study of endothelial dysfunction such as hypertension, hypercholesterolemia, and diabetes.
In vitro	Microglia cultures under hyperoxic conditions were supplemented with or without Tetrahydrobiopterin (100 μM). Exposure of microglia to hyperoxia-induced oxidative stress for 24 h showed a significant increase in TSP-1 mRNA expression and protein compared with normoxia (21% O2). Tetrahydrobiopterin supplementation significantly prevents hyperoxia-induced microglial activation and prevents microvascular damage in choroidal explants by reducing Iba-1 and TSP-1 expression.[1]
In vivo	To assess the levels of tetrahydrobiopterin in the retina, three to five retinal pools were collected from WT and HPH-1 mice at postnatal ages 7, 14, and 22 years and evaluated by LC-MS/MS. LC-MS/MS analysis confirmed that the concentration level of tetrahydrobiopterin in the retinal tissue of HPH-1 mice was significantly reduced by approximately 90% compared with WT groups P7, P14, and P22, respectively.[1]

Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, TargetMol | Animal experiments

and a total of 10 animals are to be administered, using a formulation of TargetMol | reagent

10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH₂O , the resulting working solution concentration would be 2 mg/mL.

Stock Solution Preparation:

Dissolve 2 mg of the compound in 100 μL DMSO TargetMol | reagent to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.

Preparation of the In Vivo Formulation:

1) Add 100 μL of the DMSO TargetMol | reagent stock solution to 400 μL PEG300 and mix thoroughly until the solution becomes clear.

2) Add 50 μL Tween 80 and mix well until fully clarified.

3) Add 450 μL Saline,PBS or ddH₂O TargetMol | reagent and mix thoroughly until a homogeneous solution is obtained.

This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.

All co-solvents required for this protocol, includingDMSO, PEG300/PEG400, Tween 80, SBE-β-CD, and Corn oil, are available for purchase on the TargetMol website.
