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.

M503227200 Used as a transfection enhancement reagent, the mechanisms by which CQ enhances gene expression remain unclear. CQ is a weak base with pKas of 8.1 and 10.215 and is known to buffer the luminal pH of endosomes.16,17 The buffering activity of CQ could improve transfection efficiency by facilitating DNA release from the endocytic pathway as it may Article On the Mechanism of Chloroquine Resistance. daily without chloroquine is not as abundant as a single one-time collection between 48-60 hours after initial transfection with chloroquine. 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.

ATP currents is regulated by chloroquine interaction with a different site, and likely involves disruption of interactions between Kir6.2/SUR2A and PIP 2. Our findings reveal multiple mechanisms of K ATP channel inhibition by chloroquine, highlighting the numerous convergent regulatory mechanisms of these ligand-dependent ion channels. Chloroquine is an inhibitor of the lysosomal degradation of the DNA which is taken up by the cells, so as leelee said, transfection should have been successful, albeit at a slightly lower level than if you would have added the chloroquine. In my normal transfections, I never add chloroquine and get high efficiencies nevertheless. Chloroquine has been used to increase transfection efficiency for calcium phosphate, DEAE-dextran, and some liposome-mediated gene delivery 63,65–68. However, effects of lysosomotropic agents on polymer and some lipid based methods of gene delivery are still controversial in the literature.
