Biological Activity

Description FIN56 is a specific inducer of ferroptosis .
Ferroptosis [1]
In vitro

FIN56 is a specific inducer of ferroptosis. The mechanism involves two distinct pathways: one pathway is degradation of GPX4, which requires the enzymatic activity of acetyl-CoA carboxylase; the other pathway is activation of squalene synthase, which leads to coenzyme Q10 depletion, in a manner independent of GPX4 degradation[1].


Cell Research:


- Collapse
  • Cell lines: HT-1080 cells
  • Concentrations: 5 μM
  • Incubation Time: 10 h
  • Method:

    500,000 HT-1080 cells are seeded in a 10-cm dish. Cells are grown at 37 °C for 16 h. On the day of the analysis, cells are cotreated with 100 μM α-tocopherol and either vehicle (DMSO) or a ferroptosis inducer (10 μM erastin, 0.5 μM (1S, 3R)-RSL3, or 5 μM FIN56) and incubated for 10 h. Cells are then trypsinized, pelleted, washed once with 400 μL of ice-cold PBS containing 1 mM EDTA, and sonicated. After the cell debris have been pelleted and removed, both oxidized and reduced glutathione in 120 μL of sample is quantified in technical triplicates. The glutathione quantity is normalized to the protein concentration measured via Bradford assay.

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.
