In vivo batch selection In vivo Batch:
Homogeneous suspension	CMC-NA	≥5mg/ml	Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O Validated by Selleck labs. Should you need adjustments to this formulation, contact our sales team for custom testing.	5.000mg/ml (6.05mM)	Taking the 1 mL working solution as an example, add 50 μL of 100 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC₅₀/Ki	microtubule ^[1]
In vitro	Eribulin Mesylate (1-100 nM; 72 h) inhibits cells proliferation of LM8 and Dunn cells. This compound (10-50 nM; 12-72 h) increases early apoptosis significantly in LM8 cells. It (10-50 nM; 12-72 h) induces G2/M arrest by 12 h treatment with at the dose of 50 nM, but not by long-term treatment (72 h) with 10 nM in LM8 cells. This chemical (1-10 nM; 16 h) induces morphological change and suppresses cell migration in a low concentration in LM8 cells.^[2]
In vivo	Eribulin Mesylate reduces primary tumor growth and lung metastasis of osteosarcoma in mice.^[2]
