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: ≥ 5.25 mg/mL (13.73 mM); Clear solution
This protocol yields a clear solution of ≥ 5.25 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (52.5 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: ≥ 5.25 mg/mL (13.73 mM); Clear solution
This protocol yields a clear solution of ≥ 5.25 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (52.5 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.

Cell Cytotoxicity Assay
Cytotoxicity assays are usually based on the assessment of cell membrane damage, which can also be indirectly detected by measuring cell viability. Detection methods include MTT assay, CKK-8 assay, LDH assay and ATP assay, etc.

CFSE Dye Dilution Proliferation Assay
The CFSE (carboxyfluorescein diacetate succinimidyl ester) dye dilution proliferation assay is based on the covalent labeling of intracellular proteins by a cell-permeant fluorescent dye that becomes fluorescent upon intracellular ester cleavage and then is stably retained within cells. As labeled cells divide, the dye is partitioned equally between daughter cells, resulting in a stepwise halving of fluorescence intensity that can be quantified by flow cytometry to determine the number of cell divisions undergone by each cell population. This fluorescence dilution approach enables quantitative tracking of lymphocyte proliferation at the single-cell level over multiple rounds of division. CFSE-based proliferation analysis has been widely applied to measure antigen-driven lymphocyte expansion in vitro, where discrete fluorescence peaks correspond to successive cell divisions and allow reconstruction of proliferative history within heterogeneous populations.

Dye-dilution cell tracking and proliferation staining
Dye-dilution cell tracking assays quantify cell proliferation by covalently labeling intracellular proteins with a stable fluorescent dye that is equally partitioned between daughter cells during mitosis, resulting in stepwise halving of fluorescence intensity with each cell division as measured by flow cytometry histograms. Carboxyfluorescein diacetate succinimidyl ester (CFSE) is a prototypical dye that diffuses into cells, is enzymatically converted into a fluorescent compound, and then covalently binds intracellular amine groups, producing long-lived fluorescence suitable for tracking multiple rounds of division in vitro and in vivo. Successive generations of dividing cells form discrete peaks of decreasing fluorescence intensity, enabling estimation of proliferation history, precursor frequency, and division index within heterogeneous populations. Alternative dyes such as CellTrace Violet (CTV) and far-red membrane dyes (e. g. , PKH26) follow the same dilution principle but differ
