Description

Hexadimethrine bromide (Polybrene) is a cationic polymer used routinely to enhance the efficiency of retrovirus vector-mediated gene transfer[1][2].

In Vitro

Hexadimethrine bromide inhibits human mesenchymal stem cell proliferation during lentiviral transduction. Hexadimethrine bromide is considered non-toxic at low concentrations, but has been found to negatively affect cell proliferation in some cell types at concentrations greater than 10 µg/mL. Trypsinized cells exposed to Hexadimethrine bromide are visibly larger in size when viewed under the microscope[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: ≥ 0.5 mg/mL (Infinity mM); Clear solution

    This protocol yields a clear solution of ≥ 0.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (5.0 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: ≥ 0.5 mg/mL (Infinity mM); Clear solution

    This protocol yields a clear solution of ≥ 0.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (5.0 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.

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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.

Cell Assay
[1]

Trypsinized cells are washed and resuspended in medium at 2×104 cells/mL with or without rhFGF-2 (final concentration=10 ng/mL, PeproTech) and with or without Hexadimethrine bromide at a final Hexadimethrine bromide concentration of 1, 4, or 8 µg/mL. The different conditions are seeded in 96-well plates at 1×103 cells in 50 µL per well in triplicate and cultured at 37°C, 5% CO2. After 6, 9, or 24 hr, the medium is changed and subsequent medium changes occurred every 3-4 days with 50 µL of ± FGF-2 medium (10 ng/mL). Plates are harvested on day 4, 7, 14, and 21 by removing the medium and placing the plates in the -80°C freezer until the day of analysis. The CyQUANT assay is then performed on the wells[1].

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.
