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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (6.30 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 (6.30 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 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Protocols
-
Cell migration
Cell migration is a method that plays an important role in wound healing, cell differentiation, embryonic development, etc.
-
Chemotaxis Gradient Chamber Assay 1
The chemotaxis gradient chamber assay is based on the principle of observing directional cell migration in response to a stable, linear or quasi-linear concentration gradient of a chemoattractant formed between two fluid reservoirs separated by a narrow observation chamber. Cells placed within the chamber respond to the gradient by polarized movement toward higher chemoattractant concentrations, allowing quantification of chemotactic behavior in real time under microscopy. The classic Zigmond chamber design enables simultaneous visualization of gradient formation and individual cell trajectories, making it suitable for studying leukocyte chemotaxis and other motile cell types in vitro.
-
Under-Agarose Cell Migration Assay
The under-agarose cell migration assay is a classical in vitro chemotaxis method designed to evaluate directed cell movement through a semi-solid agarose matrix toward soluble chemoattractant gradients, enabling visualization and quantification of leukocyte or motile cell migration in a confined 2D-like environment. In this system, cells and chemoattractants are placed in separate wells cut into an agarose gel, allowing diffusion-driven gradient formation that guides directional migration, which is typically assessed by measuring migration distance, cell morphology changes, and accumulation toward the chemoattractant source. This assay has been widely used to study neutrophil and leukocyte chemotaxis as a simple alternative to filter-based migration systems and allows direct microscopic observation of migrating cells under near-physiological confinement conditions.
-
Transwell/Boyden Chamber Migration Assay
The Transwell/Boyden chamber migration assay measures cell movement through a porous membrane separating an upper and lower chamber, usually after a chemoattractant gradient is established by placing cells in the upper chamber and chemoattractant-containing medium in the lower chamber. The readout is generated by quantifying cells that traverse the membrane and appear on the lower membrane surface or in the lower chamber, depending on whether the cell type is adherent or non-adherent. This assay reflects chemotactic or haptotactic migration rather than matrix invasion unless an extracellular-matrix barrier is added to the membrane.
-
Chemotaxis Gradient Chamber Assay 2
Chemotaxis gradient chamber assays measure directional cell migration in response to a soluble chemical gradient by imaging cells as they move across a defined observation region; the readout is generated from time-lapse cell trajectories, displacement toward the gradient, forward migration index, trajectory plots, rose/polar plots, and statistical tests of non-random directionality. The Dunn chamber is a direct-viewing glass chamber in which cells migrate across a bridge between control and chemoattractant wells, allowing observation of cells in a linear concentration gradient; related direct-viewing formats include the Insall chamber, which supports defined unidirectional gradients and high numerical-aperture microscopy, and the μ-Slide Chemotaxis chamber, which supports long-term live-cell imaging and gradient characterization with fluorescent dye.
