Propiolactone
Based on 1 publication(s) in Google Scholar
Propiolactone (β-propiolactone; 2-Oxetanone) is a viral chemical inactivator that causes the infectious inactivation of viruses. Propiolactone was co-incubated with SARS-CoV at a ratio of 1:1000 (v:v) and used as a bacteriostatic agent to formulate the BPL-inactivated influenza virus vaccine (Flu-BPL).

Biological Activity
SARS-CoV-2[1]
Propiolactone (β-propiolactone) can be used for vaccine purification. After cells were harvested by low-speed centrifugation, SARS-CoV was chemically inactivated with Propiolactone (1:1000 v:v). Propiolactone was incubated with SARS-CoV for 24 h at 4°C. A second incubation at room temperature was performed to hydrolyze residual propiolactone. and concentration of the vaccine. Following BPL inactivation. a polvethylene glycol-sodium chloride (PEG-NaCl) mixture was added to precipitate the inactivated virus. After cen and concentration of the vaccine. After propiolactone inactivation, a polyethylene glycol-sodium chloride (PEG-NaCl) mixture is added to precipitate the inactivated virus. Finally, Propiolactone (1:10000 v:v) was added as a bacteriostatic agent.
Propiolactone-inactivated virus loses infectivity in Vero cells[1].
Note: Propiolactone is unstable in water and prone to hydrolysis. It should be used immediately after being dissolved in water.

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 (34.69 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 (34.69 mM); Clear solution
