    The soluble complex is added to the cells, which take it up by nonspecific endocytosis. The method described here uses an initial incubation with a DNA/DEAE-dextran mixture, followed by a second incubation in growth medium supplemented with chloroquine.

    Two protocols for DEAEdextran transfection of cells are provided in this unit. The describes a procedure used to transfect adherent cells and the first presents a method used to transfect suspension cells. If an increase in transfection efficiency is needed, cells can be treated with chloroquine as described in the second. Transfection Methods Reagent-Based Methods DEAE-Dextran Method Overview Solution A DNA ~1–5 µg/ml diluted into 2 ml of growth medium with serum containing chloroquine Solution B DEAE-dextran solution ~50–500 µg/ml Solution C ~5 ml of DMSO Solution D Complete growth medium 1 Add solution A to solution B, then mix gently. Abstract. DEAE-dextran transfection is one of the oldest chemical, nonviral methods developed to transfer RNA or DNA to cultured mammalian cells 1, 2. Early transfection studies used viral RNA and DNA, which were easy to propagate and purify, and allowed phenotypic discrimination of the transfected mammalian cells.

    This protocol describes transfection of lymphocyte cell lines, but it can be used for transient transfection of both adherent and nonadherent cells. Chloroquine is thought to enhance transfection efficiencies by neutralizing lysosomal hydrolases, which can degrade the DNA.

  7. DEAE-dextran was the first non-viral transfection method verified by Vaheri and Pagano in 1965. DEAE-Dextran is a cationic polymer that tightly associates with the negatively charges nucleic acids. principle DNA is mixed with DEAE-dextran DNA/polymer complex comes into contact with negatively charged membrane due to excess of positive charge.

    A variation of the classical DEAE-dextran method of gene transfer was developed for efficient transfection of HeLa cells with plasmid DNA. A coincubation of the cells with chloroquine during. Chemical Methods for Transfection. Chemical transfection methods typically rely on electrostatic interactions to bind nucleic acid and to target cell membranes. These methods utilize compounds such as calcium phosphate, polycations e.g. DEAE-dextran, and liposomes, as well as more current technologies such as cationic lipids, polymers. Carried out by the DEAE-dextran chloroquine shock method Som- payrac and Danna, 1981; Gorman, 1985 with 25 pg of DNA and 1.5 mg of DEAE-dextran in 3 ml of Tris-buffered saline TBS' per 10- cm Petri dish. The DNA-containing medium was removed after 40 min at 37 "C. Cells were then incubated for 3 h at 37 "C in 6 ml of
