Transfections allow for transient expression of a gene of interest in a target cell line and can be useful for short term studies of protein function. We specifically use this protocol with Lenti-X 293T cells, a cell line optimized for production of lentiviral vectors. Chloroquine synthesis reaction Can you take plaquenil with metoprolol Plaquenil diarrhea nausea Chloroquine is thought to enhance transfection efficiencies by neutralizing lysosomal hydrolases, which can degrade the DNA. This protocol describes transfection of lymphocyte cell lines, but it can be used for transient transfection of both adherent and nonadherent cells. The total volume of transfection complex medium, DNA and ViaFect™ Transfection Reagent to add per well of a 96-well plate is 5–10μl. The following protocol is a guideline for transfecting approximately 10–20 wells, depending on the volume of ViaFect™ Transfection ReagentDNA mixture used. For additional wells, scale volumes accordingly. Gently add the diluted PEI to the diluted DNA. Add the diluted PEI dropwise while gently flicking the diluted DNA tube. Incubate the mixture 15-20 min at room temperature. Carefully transfer the transfection mix to the Lenti-X 293T packaging cells. Add the transfection mix dropwise being careful not to dislodge the cells. Last Upload: June 10, 2016 Day 0: Seed Lenti-X 293T cells (this cell line is optimized for production of lentiviral vectors) Day 1 (pm): Transfect Cells Day 2 (am): 18h post transfection - Remove media, replace with fresh media Day 3 or more (am): Observe fluorescence, harvest cells, or perform your experiment *Pro-Tips* Different brands and lots of FBS can promote or inhibit transfection. This approach can be adapted for different cell lines and different transfection reagents.

The cells should be transfected within 5-10’ of adding the chloroquine. 7. For 15cm plates, add 1.69ml of the transfection buffer to the DNA-CaCl2 solution by “bubbling”. Transient Transfection of 293T cells. Addgene General Transfection. Chloroquine and amphipathic peptide helices show synergistic.. Transfection-mediated toxicity usually leads to changes in gene expression, even in the absence of any visual toxicity. Therefore, it is important to choose a transfection method that can mitigate both observed as well as non-apparent cellular toxicity. Cationic lipids and polymers also form complexes with DNA through electrostatic interactions. After cells chloroquine-treated or untreated have been exposed to the calcium phosphate–DNA coprecipitate in growth medium for 2–6 h, remove the medium by aspiration and wash the. We describe a highly efficient stable gene transfection procedure for Chinese hamster ovary CHO cells using a modification of the calcium phosphate-DNA coprecipitation method. We have found that treatment of CHO cells with chloroquine increases the efficiency of gene transfer by up to 20-fold from approx. 0.01% to approx. 0.2% when transfection is done using the pSV2-neo plasmid. The.
