Ibi Scientific Ib02060 G418 Disulfate Solution 20 Ml
G418 DiSulfate Solution is routinely used as a selection antibiotic in cell culture gene selection applications. G418 solution is an aminoglycoside antibiotic isolated fromMicromonospora rhodorangeaand is closely related to the gentamicins; most notably, genatmicin B1. G418 is a generic name of Geneticin®.Features:Used as a selection antibiotic in cell culture gene selection applicationsPrevents protein synthesis by blocking the elongation step in prokaryotic and eukaryotic ribosomesConcentration: 50mg/mlThis product cannot be shipped to a private residence.Technical Description and Characteristics:G418 blocks polypeptide synthesis by inhibiting the elongation step in both prokaryotic and eukaryotic cells. G418 is commonly used in laboratory research to select genetically engineered cells, typically using the kanMX selectable marker.G418 is also used to select successfully transfected mammalian cells that express the neo resistance gene in addition to the gene of interest. The neo gene encodes amino-glycoside 3'-phosphotransferase; an enzyme which confers resistance to G418 disulfate and neomycin.Kill Curve / G418 Titration Protocol1) Seed cells of the parental cell line in a 24-well plate at different densities (50,000 - 100,000 and 200,000 cells /ml) and incubate the cells for 24 hours.2) Remove the medium and then add medium, with varying concentrations of antibiotic, to each well (0, 50, 100, 200, 400, 600, 800, and 1,000 ug/ml) and incubate at 37 deg C.3) Refresh the selective medium every 3 - 4 days and observe the percentage of surviving cells over time using procedures such as EMA vs Hoechst staining, flow cytometry or MTT assay.4) Determine the lowest concentration of antibiotic that kills a large majority of the cells within 14 days. This concentration should be used for selection of a stable transfected cell line.5) If necessary, repeat the experiment to narrow the antibiotic concentration range.Method: Determine Optimum Working Concentration for Selection of Mammalian Cells1) Plate cells in 0.5ml complete growth medium (ex: DMEM + 10% FBS) per/well in a 24-well tissue culture plate one day prior to introducing antibiotic selection. Cells should be 60-80% confluent prior to adding G418 disulfate. Typical cell density for adherent cells is 0.8 - 3.0 x 105 cells per/ml, and for suspension cells 2.5 - 5.0 x 105 cells/ml.2) Add increasing amounts of G418 disulfate to duplicate wells of cells plated in complete media. Make certain to include a duplicate control well with no G418 disulfate. General working concentration for G418 is 0.2mg/ml - 1.0 mg/ml.3) Replace media containing G418 every 2 - 3 days for 7 - 14 days. Examine the culture every day for viability of the cells.4) Use the lowest concentration that gives 100% cell death after 7 days under G418 disulfate selective pressure.Stock Solution:G418 disulfate is prepared as a solution at a concentration of 50mg/ml in water for quick and easy dilution factor calculations. Sterile filtration through a 0.22 micron filter is standard procedure.For more information, please see Specification Sheet and SAFETY DATA SHEET

These can include: Express delivery, Standard delivery, Economy delivery, Click & Collect, Free local collection from seller.
Returns
Your options for returning an item vary depending on what you want to return, why you want to return it, and the seller's return policy. If the item is damaged or doesn't match the listing description, you can return it even if the seller's returns policy says they don't accept returns. If you've changed your mind and no longer want an item, you can still request a return, but the seller doesn't have to accept it. If the buyer changes their mind about a purchase and wants to return an item, they may need to pay return postage costs, depending on the seller's return policy. Sellers can provide a return postage address and additional return postage information for the buyer. Sellers pay for return postage if there's a problem with the item. For example, if the item doesn't match the listing description, is damaged or defective or is counterfeit. By law, customers in the European Union also have the right to cancel the purchase of an item within 14 days beginning from the day you receive, or a third party indicated by you (other than the carrier) receives, the last good ordered by you (if delivered separately). This applies to all products except for digital items (e.g. Digital Music) that are provided immediately to you with your acknowledgment, and other items such as video, DVD, audio, video games, Sex and Sensuality products and software products where the item has been unsealed.
Refunds
Sellers have to offer a refund for certain items only if they are faulty, such as: Personalized items and custom-made items, Perishable items, Newspapers and magazines, Unwrapped CDs DVDs and computer software. If you used your PayPal balance or bank account to fund the original payment, the refunded money will go back to your PayPal account balance. If you used a credit or debit card to fund the original payment, the refunded money will go back to your card. The seller will effect the refund within three working days but it may take up to 30 days for Paypal to process the transfer. For payments funded partially by a card and partially by your balance/bank, the money taken from your card will go back to your card and the remainder will return to your PayPal balance.
