Description

Choline bitartrate is a vitamin-like essential nutrient, can affect diseases such as liver disease, atherosclerosis and neurological disorders^[1]^[2]. Choline bitartrate is a precursor for the neurotransmitter acetylcholine, as a methyl donor in various metabolic processes, and in lipid metabolism^[3].

IC₅₀ & Target

Human Endogenous Metabolite

In Vitro

Choline serves as a precursor component to two major cell membrane components: phosphatidylcholine and sphingomyelin in vitro^[3].
Choline is also a major source for methyl groups via its metabolite, betaine, which participates in S-adenosylmethionine synthesis pathways^[4].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Choline bitartrate (oral gavage; 300 mg/kg vs. 5 g/kg) is administrated. Choline restriction (300 mg/kg) provokes robust ketosis and weight loss in mice, also causes significant hepatic steatosis, inflammation, and cellular injury. when Choline is repleted, moderate ketosis and hepatic fat accumulation can be attenuated^[4].

* 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.

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.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.75 mg/mL (10.86 mM); Clear solution

This protocol yields a clear solution of ≥ 2.75 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (27.5 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.
Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.75 mg/mL (10.86 mM); Clear solution

This protocol yields a clear solution of ≥ 2.75 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (27.5 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.
Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 2.75 mg/mL (10.86 mM); Clear solution

This protocol yields a clear solution of ≥ 2.75 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (27.5 mg/mL) to 900 μL Corn oil, and mix evenly.

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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.
