    Chloroquine transfection what is


    Using various chemical or physical methods, this gene transfer technology enables the study of gene function and protein expression in a cellular environment. The development of reporter gene systems and selection methods for stable maintenance and expression of transfected DNA have greatly expanded the applications for transfection.

    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. Chloroquine is an aminoquinoline that is quinoline which is substituted at position 4 by a 5-diethylaminopentan-2-ylamino group at at position 7 by chlorine. It is used for the treatment of malaria, hepatic amoebiasis, lupus erythematosus, light-sensitive skin eruptions, and rheumatoid arthritis. Mar 11, 1983 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.

    Chemicals like calcium phosphate and diethylaminoethyl (DEAE)‐dextran or cationic lipid-based reagents coat the DNA, neutralizing or even imparting an overall positive charge to the molecule (Figure 1). Assay-based reporter technology, together with the availability of a wide array of transfection reagents, provides the foundation to study mammalian promoter and enhancer sequences, Transfection overcomes the inherent challenge of introducing negatively charged molecules (e.g., phosphate backbones of DNA and RNA) into cells with a negatively charged membrane.

  6. Chloroquine, which is generally applied to the cells along with the DNA, appears to enhance transfection efficiency by binding to the DNA11 and inhibiting its degradation by lysosomes.12 A. Preparation of DNA for Transfection Supercoiled plasmid DNA is efficiently expressed following DEAE-dextran mediated transfections.

    I usually do not use chloroquine in CaPO4 transfections, only with DEAE-dextran. It does make a difference but can be toxic. Don't leave it on your cells for more than 3 hours, so for CaPO4, add it 3 hours before you plan to harvest. Hours after transfection reaction has been applied to cells, gently remove media and replace with 10% glycerol or DMSO for 2-3 minutes. Remove and feed with complete media various references. *1 hour before transfection, replace cDMEM with cDMEM + 25 mM chloroquine. Add transfection reaction to this media, and incubate o/n JoVE. With any transfection procedure, a critical first step is to optimize the transfection conditions. Every cell type and transfection procedure has a characteristic set of requirements for optimal introduction of foreign DNA, and these conditions have a large degree of variability even among cell types that are very similar to one another.

    Abnormal Weight Gain and Gut Microbiota Modifications Are. The linear regression analysis revealed that the duration of treatment was significantly associated with a decrease in Bacteroidetes P = 0.0001, Firmicutes P = 0.002, and total bacteria P 0.00001. Abnormal weight gain is a side effect of long-term doxycycline and hydroxychloroquine treatment.
