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. Chloroquine lysosome acidification What is hydroxychloroquine side effects Plaquenil buy online Chloroquine lc3-ii Carefully transfer the transfection mix to the Lenti-X 293T packaging cells. Add the transfection mix dropwise being careful not to dislodge the cells. Incubate the cells for 18 h, or until the following morning. The following morning, carefully aspirate the media. Replace the media with 15 mL of DMEM complete. C H A P T E R 16 C ultivation and Retroviral Infection of Human Epidermal Keratinocytes Fiona M Watt, Simon Broad, and David M Prowse I. INTRODUCTION There are many techniques for culturing human epi- dermal keratinocytes, but the method described here is the one devised by Rheinwald and Green 1975. Add 22 l of 25mM chloroquine to each 15cm dish for 10cm plate 7.8 l of chloroquinei.e. final concentration = 25 M. The cells should be transfected 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”. 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.

Plate cells at 2.5×106 cells in 8 mL DMEM in a 10 cm dish one for each transfection to be done. System Retrovirus preparation using Phoenix cells. Transient Transfection of 293T cells. Production of Replication-Defective Retrovirus by Transient.. 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. In this study, the effect of chloroquine on transduction and associated toxicity of baboon CD34 cells and a variety of cell lines was studied. Materials and Methods. Cell lines. To study the effects of chloroquine on retroviral transduction of cell lines, three cell lines were chosen Hela cells, D17 and 208 F cells. Transfection, the process of introducing foreign genetic material into a eukaryotic cell, is an important tool for many cell and molecular biologists, as well as anyone studying the effects of altered gene expression on cellular physiology. Getting nucleic acids of interest—whether plasmid DNA or various types of RNA messenger, short interfering or micro—into a cell without killing it.
