Clear solution
5% DMSO 95% Corn oil
1.25mg/ml Taking the 1 mL working solution as an example, add 50 μL of 25 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
2.5mg/ml Taking the 1 mL working solution as an example, add 50 μL of 50 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <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.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

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].

Protocol (from reference)

Cell Assay:[2]
  • 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.
