METAFECTENE EASY + combines a simple and fast protocol with outstanding transfection efficiency and low toxicity. Thanks to the new FEE Technology ("Fast, Easy, Efficient") transfections can now be performed efficiently using a fixed DNA lipid ratio, rendering time consuming optimization obsolete. Because the new protocol of METAFECTENE EASY + takes only three days to complete, it also enables two consecutive tests to be performed within one week. METAFECTENE EASY + shows no serum inhibition and is the reagent of choice for sensitive cells. METAFCETENE EASY+ Manual DE 201109121505 1

1. General Information 1.1 Specifications Application Formulation Sterility Assays Shelf life Storage Transfection of mammalian cells with DNA Cationic lipids with colipids in water Tested : up to 750 (24 well); up to 160 (6 well) 1 year 15 C 1.2 Quality Control Standard transfection assay. Absence of bacterial and fungal contamination is verified using thioglycolate medium. 1.3 Explanatory Remarks Fast, Easy, Efficient the perfect description of the latest transfection reagent from Biontex. In intensive in depth research and development, we succeeded in achieving outstanding transfection results with a fixed DNA lipid ratio. This elimination of time consuming optimization processes, combined with a new simple protocol, results in significantly shorter assay times. The transfection efficiency of METAFECTENE EASY + achieves outstanding results for a wide range of cells, including sensitive strains. Storage METAFECTENE EASY + is delivered non chilled and should be stored in a freezer at approximately 15 C immediately after receipt. The reagent must be thawed before every transfection process to undergo a freeze thaw cycle which restores the optimum distribution of the liposomes. The recommended storage conditions are based on this freeze thaw cycle and are unrelated to the stability of the product. Shipping at room temperature does not affect product stability. Storage for several days at room temperature is not a problem provided that the reagent is subsequently stored again at 15 C; the number of times the product is thawed for use and re frozen is irrelevant. Cell conditions Cells to be transfected should be well proliferating and healthy. Cells which have been at full confluency for a while (before seeding) may not be transfected as efficiently as cells which are growing rapidly (70 90% coverage of the growth area). Therefore it is recommended to use regularly passaged cells for transfection experiments. Microbial contamination, for example with mycoplasma or fungi, can drastically alter transfection results. The Biontex products MycoSPY und MycoRAZOR can be used to reliably detect and effectively remove mycoplasma. Quality of genetic material To achieve optimum transfection results the DNA used should be of the maximum possible purity. Endotoxins and other contaminants can drastically reduce transfection efficiency. METAFCETENE EASY+ Manual DE 201109121505 3
2. Working Instructions 2.1 Remarks concerning the protocol Tolerance to transfection reagents may vary, sometimes significantly, depending on cell types or cell lines. In the following protocol, cells are transfected in two wells using two different volumes of DNA lipid complex (lipoplex). The evaluation of this assay serves as the basis for deciding which of the two lipoplex volumes is ideal for the transfected cells. This volume must be determined empirically for each cell type. If the lipoplex volume suitable for the cells in question is already known, only this volume need be used. The pipetting charts are given in section 2.8. The following instructions apply to wells with 1 cm² growth surface (equivalent to a single well of a 48 well plate). A conversion chart for other well formats is given at the end of this section. 2.2 Preparing the reagents First make up 1 EASY + buffer from the 10 EASY + buffer supplied. To do this, mix 1 part 10 EASY + buffer with 9 parts of sterile water suitable for cell culture under sterile conditions. Prior to transfection, bring 1x EASY + buffer and METAFECTENE EASY + to room temperature and vortex shortly. Bring the DNA solution to room temperature and mix gently. 2.3 Preparing the cells Prepare 500 µl of cell suspension at a concentration of 4 8 10 5 cells/ml in complete culture medium. Fill two wells (Well 1 and Well 2) with 250 µl of cell suspension each. 2.4 Preparing the lipoplex Place 75 µl 1 EASY + buffer in a test tube, ideally polypropylene (PP). Pipette 2.0 µl METAFECTENE EASY + into the 1 EASY + buffer and mix the solution by gently pipetting up and down once. Add 2.0 µg DNA by pipetting and mix as before. Mix gently! Shearing forces damage the lipoplex and reduce transfection efficiency. Then incubate for 15 min at RT. 2.5 Transfection Now add the lipoplex solution to the wells of cell suspension as follows: 25 µl of lipoplex in Well 1 and 50 µl in Well 2. Mix the solutions in both wells by gently pipetting up and down once. 1. Then incubate the wells under the normal conditions for the cell line used (e.g. 37 C in atmosphere containing CO 2 ). 4 METAFCETENE EASY+ Manual DE 201109121505
2.6 Evaluation Evaluation generally takes place 24 to 72 h later. The best results / highest protein production are generally obtained after 48 h. The optimum time is determined on the basis of the properties of the cells expression product and promoter activity. 2.7 Transfer to other well formats Format Area Cell suspension 1 EASY + Lipoplex volume buffer M.

When highly sensitive cells are used, replacement of the medium approx. 6 8 h after seeding may be useful. If lower cell densities are desired, the volume of cell suspension can be reduced by up to 30%. When growth is under way (6 8 h) culture medium should be added.
