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.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

製品説明	(-)-Epigallocatechin, widespread in plants, has been shown to exhibit anti-tumor, anti-cancer and anti-inflammatory functions.
in vitro	(-)-Epigallocatechin (EGC) shows the anti-proliferation effects on AML cells. EGC-treated cells show not only the suppression of FLT3, but also the suppression of phosphorylation of MAPK, AKT and STAT5. EGC suppresses FLT3 expression through Hsp90^[1]. EGC inhibits heregulin-β1 (HRG)-induced migration/invasion of MCF-7 human breast carcinoma cells. It does not cause modification of MCF-7 cell cycle phases. EGC inhibits HRG-induced phosphorylation of ErbB2/ErbB3 at a low cell confluence and does not activate Akt at either a low or high cell confluence^[2].

	実験の流れ	Cell proliferation is determined by trypan blue dye exclusion test. Briefly, cells are seeded in 6-well plates at a density of 1×10⁵ cells/ml in the presence of different concentrations of EGCG, EGC, ECG and C for 72 hours. After the treatment, 10 µl of the cell suspension is mixed with 10 µl of 0.4% trypan blue, and alive cells are counted manually using a hemacytometer.
