  1. 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.

    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 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. Chloroquine diphosphate 52 mg Deionized, distilled H 2 O 1 mL Dissolve 52 mg of chloroquine diphosphate in 1 mL of deionized, distilled H 2 O. Sterilize the solution by passing it through a 0.22-µm filter. Store the filtrate in foil-wrapped tubes at −20°C.

    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.

  5. May 07, 2001 Transfection efficiency was affected by the concentration of lysosomotropic agents. The marked transfection enhancement was observed when the amount of sucrose increased from 5 to 500 mM and the optimum transfection efficiency was found at 500 mM in all cell lines tested Fig. 2 a–c.

    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. 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. Sep 15, 2013 A concentration of 0.1 n m siRNA decreased BMPR-II protein Fig. 6 A and mRNA Fig. 6 B expression levels by ∼50% compared with the transfection control. To allow for variability between PAEC donors, concentrations of 0.1 and 1 n m siRNA were used in subsequent experiments to determine whether chloroquine can rescue BMPR-II protein expression.

    Plaquenil, hydroxychloroquine (HCQ), is an anti-malarial medication that has been proven to be useful in the treatment of patients with rheumatoid arthritis (RA), systemic lupus erythematosus (SLE) and other inflammatory and autoimmune diseases.

    Hydroxychloroquine - LiverTox - NCBI Bookshelf Hydroxychloroquine has also been used as therapy of porphyria cutanea tarda where it seems to act by increasing excretion of porphyrins. Hydroxychloroquine is available in generic forms and under the brand names of Plaquenil in tablets of 200 mg. The usual dose is 400 mg daily in one or two divided doses.
