    Using pei vs chloroquine transfection


    This procedure can be modified for alternative packaging cell lines or transfection reagents. Once produced, lentivirus can be used for a variety of downstream applications such as stable-cell line generation.

    We have developed a simple protocol to transfect mammalian cells using linear polyethylenimine PEI. Our linear PEI protocol is as effective as commercial reagents in the transfection of HeLa cells and XDC293 cells, a derivative of HEK293 cells, but at a fraction of the cost. Pro-Tip* The ratio of ug DNAug PEI needs to be empirically determined. Once a batch of PEI is prepared, transfect cells with a fluorescent plasmid using a variety of ratios. Check the cells 1-2 days after transfection to determine what ratio gives the highest percentage of GFP positive cells. Both N‐quaternization and the use of bafilomycin A1 a vacuolar proton pump inhibitor reduced the transfection efficiency of PEI by approximately two orders of magnitude. Chloroquine, which buffers lysosomes, enhanced the transfection efficiency of N‐quaternized PEIs and polylysine by 2–3‐fold.

    Test a variety of brands and lots of FBS to find one suitable with your protocols. Last Upload: August 26, 2016 *Pro-Tip* Different brands and lots of FBS can promote or inhibit transfection.

  4. As shown in Fig. 1b, the titers of lentiviral vectors produced using PEI-mediated transfection were only slightly lower than those involving the CaP-based transfection method. Also, the PEI-based method resulted in robust titers 10 7 TU/ml even though the transfection conditions had not been optimized at this point. It was also interesting.

    PEI condenses DNA into positively charged particles that bind to anionic cell surfaces. Consequently, the DNAPEI complex is endocytosed by the cells and the DNA released into the cytoplasm Sonawane et al. 2003. Our laboratory uses PEI over other cell transfection reagents because of its low cost. Transfection Reagent Ratio Optimisation in CHO-S Cells. The ratios of transfection reagent to DNA examined are listed in. Table S1 Supplementary material. For Linear PEI 25,000 Da Polysciences Europe GmbH, Germany the protocol is as follows based on 8 0.8 L of DNA and varying amounts of PEI Table S1 were diluted in Akinc and co-workers showed that bafilomycin dramatically decreased the transfection activity of PEI 25 kDa by preventing the acidification of endosomes and thus, the further protonation of PEI, whereas chloroquine did not affect PEI activity but increased that of quaternized counterparts. 31 On the other hand, PEI 1.8 kDa was completely.

    Plaquenil Side Effects on Your Eyes and Vision If you are taking Plaquenil to treat an inflammatory condition or malaria, you should be aware of the side effects that may occur to your eyes and vision. Plaquenil hydroxychloroquine is in a class of drugs called disease-modifying anti-rheumatic drugs, which are used to decrease inflammation, pain and joint damage.
