    Chloroquine in lentiviral transduction


    Transfections allow for transient expression of a gene of interest in a target cell line and can be useful for short term studies of protein function. We specifically use this protocol with Lenti-X 293T cells, a cell line optimized for production of lentiviral vectors.

    Note When transducing a lentiviral construct into a cell line for the first time, a range of volume or MOI should be tested. 2, 5, 10, and 15 µL of lentiviral particles per 1.6 x 10 4 cells or MOIs of 1, 2, and 5 should be used to determine the optimal transduction efficiency and knockdown for each cell line see Appendix. Transduction. MM chloroquine diphosphate Dissolve 0.129 g of chloroquine diphosphate salt in 10 mL of sterile water. Filter sterilize through a 0.22 μm filter. Aliquot 50-100 μL and store at -20 ℃. Aliquots can be thawed and stored at 4 ℃ prior to use. Thawed aliquots should be discarded after 1-2 months. Lentivirus Vector, Viral Production, and Transduction of Primary CD4 T Cells. The tax gene from HTLV-2 was fused with enhanced green fluorescence protein GFP, and the tax2-gfp fusion fragment was cloned into the lentivirus vector pLCEF8, in which the human elongation factor 1 α promoter drives expression of Tax2-GFP.

    Last Upload: June 10, 2016 Day 0: Seed Lenti-X 293T cells (this cell line is optimized for production of lentiviral vectors) Day 1 (pm): Transfect Cells Day 2 (am): 18h post transfection - Remove media, replace with fresh media Day 3 or more (am): Observe fluorescence, harvest cells, or perform your experiment *Pro-Tips* Different brands and lots of FBS can promote or inhibit transfection. This approach can be adapted for different cell lines and different transfection reagents.

    Rapamycin Treatment of Hematopoietic Stem Cells Enhances Lentiviral Transduction through Autophagy. To determine the role of autophagy in human CD34 + cell transduction, cells were treated with 3-methyladenine, an inhibitor of autophagy, or bafilomycin A1 or chloroquine, small molecules that cause accumulation of autophagosomes by. Titering Lentivirus Particles After a lentivirus preparation is complete, the titer will need to be determined prior to transduction. Viral titers reported for our lentiviral products are determined by p24 ELISA. This assay measures lentivirus-associated p24 capsid protein. We determine the TU/mL based upon the p24 assay from ZeptoMetrix. Chloroquine use in transfection. - Oct/14/2011 Hello all, I wanted to transfect the HEk cells with lentiviral vector. Before addition of the transfection complex I forgot to treat the cells with chloroquine. what is the purpose of chloroquine in transfection? Can anyone please tell me whether the transfection has taken place, as i forgot.
