    Chloroquine concentration transfection


    Most non-viral vectors are known to internalize in the cells by endocytosis. Therefore, low transfection efficiency of non-viral vectors may be due to intracellular degradation of input DNA in the endosomes and/or lysosomes.

    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. Prepare the DNA in HBS for application to cells. 1. About 5 minutes prior to transfection, add chloroquine to each plate to 25uM chloroquine stock is 50 mM; for 3 mL media + 1 mL DNA, add 2u1. Chloroquine acts to inhibit lysosomal DNases by neutralizing vesicle pH. Chloroquine is commonly used to study the role of endosomal acidification in cellular processes 2, 3, such as the signaling of intracellular TLRs. Moreover, Chloroquine inhibits autophagy as it raises the lysosomal pH, which leads to inhibition of both fusion of autophagosome with lysosome and lysosomal protein degradation 4. References. 1.

    We report here the effects of individual lysosomotropic agents such as chloroquine, polyvinylpyrolidone (PVP) and sucrose on β-gal expression in cultured fibroblasts COS, 293 and CHO. DNA degradation can be inhibited either by inactivating the lysosomal enzymes or obliterating endosome fusion to lysosomes using lysosomotropic agents.

  3. The concentration of chloroquine added to the growth medium and the duration of treatment are limited by the sensitivity of the cells to the toxic effect of the drug and should be determined.

    C for 2 h. Chloroquine was added to each well to a final concentration of 100 µM, and the incubation was con-tinued for an additional 3 h. Medium was aspirated from the wells, and the cells were carefully washed in 1.0 mL of PBS. Wells were replenished with 2 mLof R10 and incubated in 5% CO 2 at 37°C for a total of 24 h from the start of. Chloroquine is a member of quinolone family and is a weak intercalating agent. Chloroquine is used for treating amebiasis, rheumatoid arthritis, discoid and systemic lupus erythematosus. Application DNA intercalator. Also used to increase transfection efficiency. Chloroquine diphosphate salt has been used • in in vitro antiplasmodial assays To understand how chloroquine CQ enhances transgene expression in polycation-based, nonviral gene delivery systems, a number of CQ analogues with variations in the aliphatic amino side chain or in the aromatic ring are synthesized and investigated. Our studies indicate that the aliphatic amino moiety of CQ is essential to provide increased gene expression.

    Chloroquine Is a Zinc Ionophore - PubMed Central PMC Chloroquine is an antimalarial drug that has been used in humans for many years. In recent years, Chloroquine has been shown to inhibit autophagy and induce apoptosis in malignant cells and thus has been tested in various experimental model systems and in human clinical trials.
