Biological Activity

Description Trolox is a cell-permeable, water-soluble derivative of vitamin E with potent antioxidant properties.
In vitro

Trolox (6-hydroxy-2,5,7,8-tetramethylchroman-2-Carboxylic Acid) is a vitamin E analog and a direct scavenger of peroxyl and alkoxyl radicals. Trolox impairs PT4 cell survival, has minor effects on ROS levels and causes wide deregulation of cell cycle genes[1]. Trolox enhances As2O3-mediated apoptosis in APL, myeloma, and breast cancer cells. Trolox inhibits DNA damage formation induced by singlet oxygen in human lymphoblast WTK-1 cells and protects red blood cells during photodynamic treatment[2].

In vivo After cerebral ischemia reperfusion, Trolox prescription increases anti-apoptotic proteins and decreased proapoptotic proteins thus protects neurons of the hippocampus and caused improvement of memory[3].


Cell Research:[2]
- Collapse
  • Cell lines: NB4, IM9, and AsR2 cells
  • Concentrations: 100 μM
  • Incubation Time: 6 days
  • Method: NB4, IM9, and AsR2 cells are seeded at 1 × 105 cells/mL in 24-well plates. Cells are treated with various concentrations of As2O3 or doxorubicin, alone or in combination with 100 μM trolox for 6 days. Viable cells are counted by trypan blue exclusion on days 1, 3, and 6. All cells are maintained at a density lower than 1 × 106 cells/mL through dilution as required, and media ± treatment is replaced every third day. MCF-7, MDA-231, and T47D are seeded in 24-well plates at a density of 4000 cells/well. The next day, fresh media containing As2O3 ± trolox is added. On the days indicated, cells are fixed in 10% trichloroacetic acid and subsequently stained with sulforhodamine B (SRB). Bound SRB is solubilized in 10 mM unbuffered Tris (tris(hydroxymethyl)aminomethane), and optical density is measured at 570 nm in a microplate reader.

Bio Calculators

Molarity Calculator

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)

  • Mass
    Molecular Weight

*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

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 )

  • C1

* 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.
