Biological Activity

Description Folic acid, a B vitamin, plays an important role in cell division and in the synthesis of amino acids and nucleic acids like DNA.
In vitro

Folic acid treatment induces dose-related increases in BRCA1 mRNA expression in HepG2, Huh-7D12, Hs578T, and JURKAT and in BRCA2 in HepG2, Hs578T, MCF7, and MDA-MB-157 cells. FA does not affect the corresponding normal cells or on any of the ovarian cell lines. Folic acid induces increased BRCA1 protein expression in Hs578T, but not HepG2 cells, whereas BRCA2 protein levels are undetectable. FA treatment does not alter DNA repair in liver-derived cells, whereas there are transient effects on breast-derived cells. There is no effect of FA treatment on BRCA1 or BRCA2 DNA methylation, although there is some variation in the methylation of specific CpG loci between some cell lines[1].


Cell Research:


- Collapse
  • Cell lines: HepG2, Huh-7D12, Hs578T, JURKAT, Hs578T, MCF7, and MDA-MB-157 cells
  • Concentrations: 0, 25, 50, 75, or 100 nmol/L
  • Incubation Time: 72 h
  • Method:

    To determine the effect of FA supplementation on BRCA1 and BRCA2 mRNA expression, all cell lines were treated with 0, 25, 50, 75, or 100 nmol/L FA for 72 hours before harvesting in TRI Reagent according to the manufacturer’s instructions.

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.
