Description

In Vitro

(E)-2-octenal (0.25-2.00 mL L⁻¹; 2-4 d) inhibits the mycelial growth of prochloraz-resistant Penicillium italicum strain XX5 with an MIC of 0.25 mL L⁻¹ and MFC of 0.50 mL L⁻¹^[1].
(E)-2-octenal (1/2 MIC-MIC; 30-120 min) induces dose- and time-dependent oxidative stress in prochloraz-resistant Penicillium italicum strain XX5 mycelia, leading to ROS accumulation and lipid peroxidation^[1].
(E)-2-octenal (0.1-1.6 μL/mL; 1-4 days) inhibits mycelial growth of Neofusicoccum parvum in a concentration-dependent manner, with minimum inhibitory concentration (MIC) 0.4 μL/mL and minimum fungicidal concentration (MFC) 0.8 μL/mL^[2].
(E)-2-octenal (0.2-0.4 μL/mL) damages the morphology of Neofusicoccum parvum mycelia, with more severe damage at higher concentrations^[2].

Stock Solution Working Solution

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: ≥ 5 mg/mL (39.62 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.

Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)

Solubility: ≥ 5 mg/mL (39.62 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 900 μL 20% SBE-β-CD in Saline, and mix evenly.

Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 5 mg/mL (39.62 mM); Clear solution

This protocol yields a clear solution of ≥ 5 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 (50.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
