Tylvalosin tartrate
Based on 2 publication(s) in Google Scholar
Tylvalosin (Acetylisovaleryltylosin) tartrate is an orally active, broad-spectrum macrolide antibiotic with antimicrobial activity. Tylvalosin tartrate is an antiviral agent useful in studying PRRSV infection. Tylvalosin tartrate induces apoptosis. Tylvalosin tartrate also has anti-inflammatory activity, relieves oxidative stress, and alleviates acute lung injury by inhibiting NF-κB activation.

Tylvalosin tartrate (10 μg/mL; 0.5, 1 h) increases caspase-3 cleavage in porcine neutrophils, leading to DNA fragmentation during apoptosis [4].
Tylvalosin tartrate (0.1-10 μg/mL; 0.5 h) Promote endocytosis of porcine neutrophils by macrophages without changing phagocytosis [4].

Solvent & Solubility
DMSO : 100 mg/mL (83.87 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
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 (stored under nitrogen). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

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: ≥ 5 mg/mL (4.19 mM); Clear solution
This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 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.
