EGCG treatment increases cTnI protein levels in ageing hearts. (A) Western blotting analysis using cTnI and cTnT antibodies. b-Actin was used as protein loading control. (B) A summary of Western blotting results of cTnI. Values are expressed as mean S.D. from four separate experiments. Statistical significance was determined by ANOVA followed by least significant difference (LSD) tests. *P < 0.05 as compared with the 18M + EGCG and 3M groups. EGCG: epigallocatechin-3-gallate

(a) Huh7 cells were incubated with HCVcc of JFH-1 for 2 h before overlaying with 1% agarose dissolved in culture medium or with AR3A anti-E2 neutralizing antibodies, in the presence of 20 μg/ml SZA. EGCG (50 μM) was introduced as a positive control. At 48 h post-infection, infected cells were quantified by IF. Nuclei were stained with DAPI. (b) Numbers of cells per positive colony were determined in 15 foci.

(-)-Epigallocatechin gallate functions as a powerful antioxidant, preventing oxidative damage in healthy cells, but also as an antiangiogenic and antitumor agent and as a modulator of tumor cell response to chemotherapy. (-)-Epigallocatechin gallate shows multiple anticancer effects, such as anti-proliferation, anti-angiogenesis, transformation prevention of various cancer cells, cancer cell cycle arrest and inhibition of tumor metastasis. (-)-Epigallocatechin gallate exerts multi-anticancer effects through regulating several cancer-related cell signal pathways (regulated the function or the expression of key signal proteins, such as nuclear factor-κB, MAPKs and activator protein-1, EGFR, IGF, COX-2 signaling pathway, and so on.), effecting methylation of cancer genes and combination of ligand with membrane receptors. [1] (-)-Epigallocatechin gallate also shows an immunomodulating effects. Several types of immune cells in both the innate and adaptive immune systems are known to be affected in varying degrees by (-)-Epigallocatechin gallate. Among them, the dramatic effect on T cell functions has been repeatedly demonstrated, including T cell activation, proliferation, differentiation, and production of cytokines. Studies using animal models of autoimmune diseases have reported disease improvement in animals treated with green tea/EGCG. [2] (-)-Epigallocatechin gallate displays anti-infective properties. Antiviral activities of (-)-Epigallocatechin gallate with different modes of action have been demonstrated on diverse families of viruses, such as Retroviridae, Orthomyxoviridae and Flaviviridae and include important human pathogens like human immunodeficiency virus, influenza A virus and the hepatitis C virus.

Bio Calculators
Molarity Calculator
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
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 )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

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.
