Retroviral transduction protocol

Apr 24, 2012 · Protocol Steps: Prepare 293T Cells: 1. Grow 293T cells in a T175 flask. Note: A least 1 T175 flask per factor will be needed, so you must have at least 4 flasks. Each T175 should be fed with 32mls of 293T Media. 2. Cells should be ~85% confluent. Note: Cells are normally ready about 2 days after a 1:5 split. Transfection of 293T Cells: 3. RetroNectin reagent provides better retroviral and lentiviral transduction efficiency for hard-to-infect cell types (e.g., hematopoietic cells) than conventional transduction protocols, including those that use Polybrene. For human CD34+ cells, RetroNectin reagent can increase transduction efficiency by 50–70% (see example in Figure 1).

Troubleshooting and Optimization of Retroviral Transduction Parameters. One of the most frequent laments of using recombinant retroviruses is that the titer does not appear to be sufficient to infect the cells of interest at a high enough frequency to suit your purposes.

Retroviral transduction. Retroviruses have the ability to transform their single-stranded RNA genome into a double-stranded DNA molecule that stably integrates into the genome of dividing target cells.Retroviral infection was induced using cells producing the retroviral vector as previously described . Briefly, the viral supernatant of the producing cells was added to the MSC (between passages 3 and 8) culture medium, supplemented with polybrene (8 μg/mL) in a 1:1 ratio after filtration through a 0.45-μm-pore filter.

Feb 18, 2015 · Here we describe a new strategy for the early retroviral transduction of minimally differentiated triVSTs that produces high and stable levels of transgene expression in all three VST components and allows rapid expansion to numbers sufficient for infusion within 8 to 16 days of culture. Transfect a Platinum retrovirus packaging cell line, such as Plat-A (amphotropic) or Plat-E (ecotropic), which stably expresses both MMLV Gag-Pol and an amphotropic or ecotropic envelope protein, with a retroviral expression vector. These cells require transfection of only an expression vector to produce retrovirus.

Jan 19, 2019 · Perform a "reverse transduction" by seeding 50,000 cells into each well of the 6-well dish. These cells will be added to the wells that already contain 0.5 mL of virus solutions at various dilution. Make sure to use the polybrene-containing media to make the cell solution in this step. To seed the cells:

Day 3 • Remove the culture medium and replace with 1 ml of complete medium (without Polybrene®). • Incubate the cells overnight. Day 4 • To select stable clones expressing the shRNA, split cells 1:3 to 1:5, depending on the cell type, and continue incubating for 24–48 hours in complete medium. Day 5-6 and Forward
