Tetrahydrofolic acid (L-5,6,7,8-Tetrahydrofolic acid) is the biologically active vitamin B9 folate derivative. Tetrahydrofolic acid is a donor of one-carbon groups for amino acids, nucleic acids, and lipids. Tetrahydrofolic acid serves as an acceptor of free formaldehyde, producing 5,10-methylenetetrahydrofolate-Tetrahydrofolic acid.

Description

Tetrahydrofolic acid (L-5,6,7,8-Tetrahydrofolic acid) is the biologically active vitamin B9 folate derivative. Tetrahydrofolic acid is a donor of one-carbon groups for amino acids, nucleic acids, and lipids. Tetrahydrofolic acid serves as an acceptor of free formaldehyde, producing 5,10-methylenetetrahydrofolate-Tetrahydrofolic acid[1].

Human Endogenous Metabolite

 

In Vitro

Tetrahydrofolic acid (0-200 μM; 3 days; Adh5-/- DT40 cells) exposure is cytotoxic to Adh5- and Fanconi anemia (FA)-deficient cells due to the accumulation of extensive DNA damage and chromosome breaks[1].
Tetrahydrofolic acid (0-100 μM; 16 hours; Adh5-/- DT40 cells) treatment strongly promots FANCD2 and ser139-H2AX focus formation in Adh5-/- cells in a dose-dependent manner[1].
Tetrahydrofolic acid exposure activates the DNA damage response (DDR) due to uncontrolled activity of the thymidylate synthase enzyme, which causes a depletion of essential nucleotides, and promotes repair by a homologous recombination mechanism[1].

Cell Viability Assay[1]

Cell Line: Adh5-/- DT40 cells
Concentration: 0-200 µM
Incubation Time: 3 days
Result: Viability of Adh5-/- DT40 cells rapidly dropped.

Western Blot Analysis[1]

Cell Line: Adh5-/- DT40 cells
Concentration: 0-200 µM
Incubation Time: 16 hours
Result: Strongly promoted FANCD2 and ser139-H2AX focus formation in Adh5-/- cells in a dose-dependent manner.
In Vivo

Tetrahydrofolic acid (62.5 mg/kg; intraperitoneal injection; daily; Adh5-/- mice) treatment perturbs the hematopoiesis of hematopoietic cells, increases ser139-H2AX phosphorylation, and decreases the survival of progenitor cells (HSPCs) suggesting that excess Tetrahydrofolic acid could be mutagenic and genotoxic to bone marrow cells[1].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.08 mg/mL (4.67 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.08 mg/mL (4.67 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
