In Vitro
(-)-Epigallocatechin Gallate (EGCG, 10-60 μM) inhibits the growth of FB-2 and WRO cells in a dose-dependent manner[1].
(-)-Epigallocatechin Gallate (10-60 μM, 0-24 h) reduces cyclin D1 and phosphorylation of AKT and ERK1/2, and increases p21 and p53 expression[1].
(-)-Epigallocatechin Gallate (10-60 μM, 12 h) reduces cell motility and migration[1].
(-)-Epigallocatechin Gallate (0-20 μM, 0-20 min approximately) inhibits GLUD1/2 and IDH1 activity in a concentration and time-dependent way (biochemical assays)[2].
(-)-Epigallocatechin Gallate (0-35 μg/mL, 24-72 h) inhibits the proliferation of colorectal cancer cells (LoVo, SW480, HT-29, HCT-8 cells), increases cell apoptosis and blocks cells at the G0/G1 phase[3].

*Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles. Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
*
Note: If you choose water as the stock solution, please dilute it to the working solution,
then filter and sterilize it with a 0.22 μm filter before use.
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
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μLDMSO stock solution (20.8 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.
Protocol 2
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.
Taking 1 mL working solution as an example, add 100 μLDMSO stock solution (20.8 mg/mL) to 900 μLCorn oil, and mix evenly.
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.

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.
