If you use 6-well or 12-well plates, total volume of the medium should be 3ml and 1.5ml, respectively, and decrease the amount of each reagent accordingly.2. One hour prior to the transfection, change to medium containing 25M chloroquine (from x1000 stock in PBS, stored at -20C). (Chloroquine can be omitted, but increases efficiency about x2) to a final volume of 500 l. Plaquenil side effects bone pain Safe dosage of plaquenil Plaquenil reduces preeclampsia Does plaquenil cause acne Chloroquine treatment of rodent cells during the first hours of polyoma DNA transfection increase the fraction of cells expressing viral functions. The effect has been observed after DNA absorption using both the DEAE-dextran and calcium phosphate coprecipitation methods. Transfection of 293T cells • Calcium Phosphate transfection reagents self-made or kits, e.g. Promega ProFection or Sigma #CAPHOS. • Add 10ml medium including 25µM Chloroquine the Chloroquine is used in this step only. Use fluorescence microscope to check transfection, cells should be already very bright. Protocol for Lentivial Vector LV Production 2nd Generation Packaging Lenti virus can be packaged by any transfection reagent. In this protocol, we describe two methods a calcium phosphate precipitation method and an iMFectin Poly DNA method. Add this mixture directly to the cells dropwise through the medium. As long as the cells are alive, they produce proteins. When you are ready, add 500 l of 2x HBS dropwise while gently mixing. Make sure you evenly sprinkle the droplet over the entire area.5. For secreted protein, you can change media once (at day 3 or 4, save the collected sup) and give it another 3-4 days of culture.

Twenty-four hours prior to transfection, inoculate 1 to 2 x106 cells/10 cm plate or, inoculate 3x106 cells/plate 16-hours prior to transfection. in 10 ml DMEM media + 10% BCS supplemented with L-glutamine and Pen/Strep. At the time of transfection, cells should be about 30-40%. Calcium Phosphate Transfection of 293T Cells. Protocol for Lentivial Vector LV Production 2nd.. Glycerol shock or chloroquine? - Transfection and Transduction. Transient assays for gene expression in transfected cells are performed 48-72hrs post transfection. Some cells are Calcium tolerant and can live in the presence of Ca overnight, while other cells are Calcium intolerant and should be exposed to the precipitate for no longer than 4-6 hours. Calcium phosphate transfection is the method of choice to produce long-term stable transfectants. This method also works well for transient expression of transfected genes and can be used with most adherent cell lines. 2. Product Components and Storage Conditions Product Cat.# ProFection® Mammalian Transfection System—Calcium Phosphate E1200 The Calcium Phosphate Transfection Kit provides high-quality reagents to enable the introduction of DNA into eukaryotic cells via calcium phosphate co-precipitation. How it works The calcium phosphate transfection method for introducing DNA into mammalian cells is based on forming a calcium phosphate-DNA precipitate.
