Ractopamine hydrochloride
Based on 1 Customer Validation
Ractopamine hydrochloride (LY031537) is a potent and orally active β-adrenergic receptor (βAR) agonist with Kd value of ~25 nM for pig β1AR and β2AR. Ractopamine hydrochloride also is a mTAAR1 agonist with an EC50 of 16 μM. Ractopamine hydrochloride promotes muscle mass development, limits fat deposition, reduces feed consumption, increases total cellular protein synthesis, and improves growth rate and feed efficiency in finishing swine. Ractopamine hydrochloride can be used for researching to increase lean tissue growth and improve production efficiency in pigs.

Biological Activity
Ractopamine (50 nM-100 μM) hydrochloride acts as a full agonist of mouse trace amine-associated receptor 1 (mTAAR1) in Xenopus laevis oocytes coexpressing hCFTR and mTAAR1, with an EC50 of 16 μM, via a cAMP-dependent pathway[1].
Ractopamine hydrochloride increases protein accumulation and synthesis in postfusion ELC5 myotubes in a concentration-dependent manner[3].
Ractopamine hydrochloride shows Kd value of ~25 nM for pig β1AR and β2AR[5].

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: ≥ 2.5 mg/mL (7.40 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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: ≥ 2.5 mg/mL (7.40 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.
