    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.

    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. For CaPO3, I use chloroquine, which inhibits DNA degradation by lysosomes by raising their pH - but this is toxic to the cell, so media must be changed after 6-8 hr. PEI also prevents DNA. The results showed that in the presence of the drug, the transfection efficiency is reduced by 7- to 200-fold, depending on the cell line Akinc et al. 2005; Kichler et al. 2001; Yue et al. 2011. These data clearly indicate that the acidification process is involved in the PEI-mediated transfection mechanism.

    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.

  3. Culture cells in chloroquine for 30 mins - prepare transfection cocktail structural vector, sample vector, envelope vector, Calcium chloride - Add 2X HBS to the cocktail containing 50mM HEPES, 10mM KCl, 12mM Dextrose, 280nM NaCl, 1.5mM Na2HPO4 - add to cells and viola! Beautiful GFP expression the following day.

    Within 5-10’ of adding the chloroquine. 7. For 15cm plates, add 1.69ml of the transfection buffer to the DNA-CaCl2 solution by “bubbling”. To “bubble”, use two mechanical pipeters Pipet-AidTM, one with a 1ml pipette to bubble air into the DNA-CaCl2 solution and the other to slowly drip the transfection buffer into the conical tube. 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 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.

    Lupus hot flashes - Tips and Tricks From Doctors Hot flashes are caused by an imbalance between multiple hormones but especially estrogen and progesterone. The symptoms can occur several times a day. They are often associated with filling hot all over causing one to want to take off some of their clothing. There is a syndrome called estrogen dominance.
