Description

Blebbistatin is a selective non-muscle myosin II (NMII) inhibitor, promotes directional migration of corneal endothelial cells (CECs) and accelerates wound healing, and better preserves cell junctional integrity and barrier function. Blebbistatin blocks cell migration[1][2].

IC50 & Target

Non-muscle myosin II (NMII)[1]

In Vitro

The therapeutic potential of targeting NMII to enhance CEC migration is investigated using bovine corneal endothelial cells (BCECs). Blebbistatin, a direct myosin motor inhibitor, promotes migration and directional persistence in CECs through decreasing actin retrograde flow and increasing lamellipodial protrusion persistence to accelerate wound healing in vitro[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Blebbistatin (0.05 mL, 20 μM; intracameral injection; daily; for 6 days; New Zealand white rabbits) treatment promotes wound healing in rabbit corneal endothelial scraping model[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: New Zealand white rabbits (16-20 weeks; 3-3.5 kg)[1]
Dosage: 0.05 mL; 20 μM
Administration: Intracameral injection; daily; for 6 days
Result: Resulted in significant improvement of corneal clarity and corneal edema resolution, implying the restoration of an intact corneal endothelial monolayer.

In Vivo:

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.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: 2.5 mg/mL (8.55 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 2.5 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 (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.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
