Ligustrazine (Chuanxiongzine) is an orally active, blood-brain barrier-permeable alkaloid. It can be isolated from Ligusticum striatum DC. Ligustrazine reduces ROS, upregulates the levels of p-Akt/Akt and p-eNOS/eNOS, and decreases ALT and AST. It inhibits glutamate excitotoxicity, calcium overload, oxidative stress, ischemia-reperfusion injury and atherosclerotic plaque progression, enhances synaptic plasticity, and improves neurological function, cerebral infarct volume and brain water content. Ligustrazine possesses anti-inflammatory, antioxidant, lipid-lowering, endothelial protective and hepatoprotective activities. It can be used in studies related to ischemic stroke, cerebral ischemia-reperfusion injury and atherosclerosis.

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.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Working Solution

For the following dissolution methods, please prepare the working solution directly:

It is recommended to prepare fresh solutions and use them promptly within a short period of time.

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: 0.5% CMC-Na/0.5% Tween-80 in Saline water

Solubility: 15.92 mg/mL (116.89 mM); Suspended solution; Need ultrasonic

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.
