Standard Protocols:

Protocol I: siRNA Transfection per Cell Culture Vessel

1. Preparation of Working Solution (1X):

  • Dilute the Transfection Buffer (5X) with ddH2O at a 1:4 ratio to obtain a Working Solution (1X). Store at room temperature for up to 24 months.

2. Cell Seeding:

  • Plate cells 18 to 24 hours prior to transfection to achieve approximately 50% confluency at the time of transfection.
  • Add complete medium containing serum and antibiotics to each vessel 30-60 minutes before transfection.

3. siRNA Transfection:

  • Recommended siRNA concentrations range from 1 to 100 nM. Start with 5.0 nM siRNA for most adherent cell lines, adjusting to 50 nM for challenging cell types.
  • Follow these steps per vessel:
a. Add complete medium with serum and antibiotics.
b. Dilute siRNA into the Working Solution (1X) and mix.
c. Add the Transfection Reagent to the siRNA solution and mix gently.
d. Incubate for approximately 15 minutes at room temperature.
e. Add the transfection mix drop-wise to the cells.
f. Replace transfection medium with growth medium approximately 5 hours post-transfection if needed.
 

4. Assessment:

  • Evaluate gene silencing 24-72 hours after transfection using appropriate assays. Adjust conditions based on cell type and experimental requirements.

Protocol II: DNA/siRNA Co-transfection:

1. Preparation of Working Solution (1X):

  • Dilute the Transfection Buffer (5X) with ddH2O at a ratio of 1:4 to create a stable Working Solution (1X). Store at room temperature for up to 24 months.
  • Note: Maintain the Transfection Buffer (5X) at room temperature to prevent precipitation. Refrigeration may induce white precipitates, which do not compromise transfection efficiency. Upon dilution to Working Solution (1X), any precipitates will dissolve.

2. Cell Seeding:

  • Plate cells 18 to 24 hours before transfection to achieve approximately 70% confluency at the time of transfection.
  • Add complete medium containing serum and antibiotics to each vessel 30-60 minutes before transfection.
  • Note: The Transfection Reagent is compatible with serum and antibiotics throughout the experiment.

3. DNA & siRNA Co-transfection Protocol:

  • Recommended for each vessel: Use 0.3-0.5 µg DNA and 1-20 nM siRNA, starting with 0.5 µg DNA and 10 pmoles siRNA (final concentration 10 nM) per vessel.
  • Follow these steps per vessel:
a. Add complete medium with serum and antibiotics.
b. Dilute 0.5 µg DNA and 10 pmoles siRNA into 100 µL of the  Working Solution (1X) and mix thoroughly.
Note: Use the Working Solution (1X) for optimal transfection efficiency and maximal gene silencing.
c. Prepare siRNA stock solution at 10 µM and add 1.0 µL per vessel for a final 10 nM siRNA concentration.
d. Add 3 µL of the Transfection Reagent immediately and mix gently.
e.Incubate for approximately 15 minutes at room temperature to allow transfection complex formation. Do not exceed 30 minutes.
f. Add the transfection complex drop-wise to the cells.
g. Gently rock the vessel and return it to the incubator.
h. Replace the transfection medium with cell growth medium approximately 5 hours post-transfection if necessary.
 

4. Assessment:

  • Assess gene silencing 24-72 hours post-transfection. Adjust parameters based on cell type and experimental requirements.

Protocol III: DNA transfection to Mammalian Cells

1. Preparation of Working Solution (1X):

  • Dilute the Transfection Buffer (5X) with ddH2O at a ratio of 1:4 to create a stable Working Solution (1X). Store at room temperature for up to 24 months.
  • Note: Maintain the Transfection Buffer (5X) at room temperature to prevent precipitation. Refrigeration may induce white precipitates, which do not compromise transfection efficiency. Upon dilution to Working Solution (1X), any precipitates will dissolve.

2. Cell Seeding:

  • Plate cells 18 to 24 hours before transfection to achieve approximately 80% confluency at the time of transfection. Add complete medium containing serum and antibiotics to each vessel 30-60 minutes before transfection.
  • Note: the Transfection Rreagent is compatible with serum and antibiotics throughout the experiment.

3. DNA Transfection Protocol:

  • Recommended for each vessel: Use 0.5 to 1.0 µg DNA per well in a 6-well plate. Starting with 1.0 µg DNA and 3.0 µL of the Transfection Reagent per well typically yields satisfactory efficiency without visible toxicity.
  • Follow these steps per vessel:
a. Add 1.0 mL of complete medium with serum and antibiotics to each well 30-60 minutes before transfection.
b. Dilute 1.0 µg DNA into 100 µL of the Working Solution (1X) and mix thoroughly.
Note: Use the Working Solution (1X) for optimal transfection efficiency and maximal gene expression.
c. Add 3 µL of the Transfection Reagent and vortex briefly.
d. Incubate for approximately 10 minutes at room temperature to allow transfection complex formation. Do not exceed 20 minutes.
e. Add the transfection complex drop-wise to the cells.
f. Gently rock the vessel and return it to the incubator.
g. Replace the transfection medium with cell growth medium 24 hours after transfection and proceed with analysis as required. h. Adjust parameters based on cell type and experimental requirements.
