Biological Activity

Description (-)-Epicatechin gallate (ECG) is an inhibitor of cyclooxygenase-1 (COX-1) with IC50 of 7.5 μM.
In vitro

Treatment of HuH7 cells with (–)-Epigallocatechin gallate (EGCG) causes a time- and dose-dependent decrease in the expression of VEGFR-2 and p-VEGFR-2 proteins. EGCG effectively suppresses the growth of HuH7 human HCC cells both in vitro and in vivo[1]. EGCG potently modulates cardiac excitation contraction coupling by acting on RyR and possibly on L-type Ca2+-channel and NaCa exchanger[2].

In vivo Drinking of EGCG significantly inhibits the growth of HuH7 xenografts in nude mice and this is associated with inhibition of the activation of VEGFR-2 and its related downstream signaling molecules, including ERK and Akt. EGCG drinking also decreases the expression of Bcl-xL protein and VEGF mRNA in the xenografts[1].


Cell Research:[1]
- Collapse
  • Cell lines: HuH7 or Hc cells
  • Concentrations: 0-100 μg/mL
  • Incubation Time: 48 h
  • Method: Three thousand HuH7 or Hc cells are seeded into 96-well plates. Twenty-four hours later, the cells are treated with the indicated concentrations of EGCG (0–100 μg/mL) for 48 h in DF10 medium, and cell viability is examined. All assays are carried out in triplicate.

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and SDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
