Product Introduction

Bioactivity

Description	L-Ornithine ((S)-2, 5-diaminopentanoic acid) is a non-protein amino acid. L-Ornithine is mainly used in the urea cycle to remove excess nitrogen from the body. L-Ornithine is renoprotective. L-Ornithine has antifatigue effects.
Targets&IC50	Arginase (bovine):1.02 mM (Ki)
In vitro	METHODS: HK-2 cells were treated with L-Ornithine (100, 300 μM) for 24 hours, and ROS levels were measured using fluorescence microscopy. RESULTS: Ornithine protected HK-2 cells from ROS production. [1]
In vivo	METHODS: To investigate the effect of L-Ornithine on peripheral clock gene expression, mice were orally treated with L-Ornithine (1000 mg/kg) for 3 days. RESULTS: The phase of PER2 gene expression in liver, submandibular gland and kidney was significantly advanced in L-Ornithine treated mice. [2] METHODS: To investigate the effect of L-Ornithine on sleep behavior, L-Ornithine was added to the diet of maternal mice, and its effect on the sleep behavior of offspring mice was observed. RESULTS: L-Ornithine supplementation increased sleep-like behavior in mice. [3] METHODS: To study the effect of L-Ornithine on acute necrotizing pancreatitis, rats were intraperitoneally injected with L-Ornithine (3 g/kg). RESULTS: Severe acute necrotizing pancreatitis was induced by L-Ornithine in rats. [4]

In Vivo Formulation Calculator (Clear solution)

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.
