Retro-2 (1 μM; 1-4 hours) induces autophagy in GFP-LC3-expressing HeLa cells and promoted the dramatic cytoplasmic accumulation of large autophagosomes[2].
Retro-2 (1 μM; 0.5-4 hours) treatment hows an increase over time of the abundance of LC3-II protein in cells[2].
Retro-2 impairs the trafficking between autophagosomes and lysosomes. Retro-2 abolishes autolysosomes formation[2].
Retro-2 (20 μM; pretreatment for 30 min) inhibits HeLa cell intoxication by ricin, Shiga-like toxins 1 (Stx1) and 2 (Stx2)[1].
Retro-2 blocked invasion of cells by the intracellular parasite Leishmania, as well as replication of non-enveloped viruses, including polyoma-, papilloma-, and adeno-associated viruses[3].

Solvent & Solubility
DMSO : 250 mg/mL (780.25 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 (protect from light). 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: 2.08 mg/mL (6.49 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.08 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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: 2.08 mg/mL (6.49 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.08 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.
