XtremeGENE HP DNA Transfection Reagent is a high performance reagent that transfects a broad range of eukaryotic cells, including insect cells and hardtotransfect cell lines (e.g., Sf9, U2 OS, MEF, MCF7, Hep G2, PC3, HeLa, HT29, HT1080, K562, RAW 264.7, Jurkat, PC12, and HCT 116). Benefit from an easytouse nonliposomal reagent that is free of animalderived components, stable at room temperature, filtered through 0.2 μm pore size membrane, and active in serumcontaining medium. Achieve new levels of transfection efficiency in primary cells and tumor cell lines that are not transfected well by other reagents. Generate physiologically relevant data using a reagent with low cytotoxic effects. Increase experimental throughput and enable target evaluation using a simple and consistent protocol. Quality Each lot of XtremeGENE HP DNA Transfection Reagent is carefully tested following established quality procedures to ensure that the product is consistently

DSD 867 MET screens saliva sample for the following common drugs Detection Levels, Abbreviations & Detection Times Cannabis 12ng/ml THC up to 12hrs Cocaine 20ng/ml COC up to 24 hrs Opiates 40ng/ml OPI Opiate & Heroin up to 48 hrs Amphetamine 50ng/ml AMP up to 72hrs Methamphetamine 50ng/ml MET up to 72hrs Benzodiazepine 50ng/ml BZO up to 48 hrs How to use a DSD867 saliva drug testing kit It is not a matter of just wiping the drug test swab around the mouth as many people think, the collection sponge needs to be well saturated with saliva, so that there is enough oral fluid collected to run the drug test. If the saliva sample is inadequate the drug test will not work ( ie no results ) Tips for using this type of saliva drug test kit Make sure that the saliva collection sponge is well soaked with saliva. It can take up to 23 minutes to collect a good sample. Pop the collection sponge into the pot and screw it right down

Virtually painfree lancing Clixmotion technology controls the lancet’s movement Less sidetoside motion of the lancet means less skin damage Turn the rotatable cap for 11 penetration depth settings for different skin types The AccuChek Softclix lancets are precisely manufactured for precise entry Additional specification Penetration Depth 11 fixeddepth options, set with the rotatable cap Penetration Range 0.8 to 2.3 mm Lancing Technology Clixmotion Technology Weight 21 g Alternative Site Testing AST cap provided Needle Diameter 0.4 mm Gauge 28 Coating Silicon How to use the AccuChek Softclix lancing device The AccuChek Softclix lancing device is small and easy to operate, with onehand priming and lancing. Pull off the cap. Insert a new lancet into the lancet holder and push it in until it clicks. Press the cap on again until it clicks. Rotate the cap until the desired penetration depth is set. Press the priming button down until it clicks.

DNA with either blunt or sticky ends (≤200 ng). Heat inactivation 10 min at 65 °C (T4 Ligase) Inactivation of T4 Ligase is necessary only if the ligation reaction mixture is to be used in experiments other than transformation assays. Note Heat inactivation of the ligation reaction mixture before transformation causes the number of transformed colonies to decrease drastically (> factor of 20). Star activity Star activity should also be avoided. When double digests are performed with enzymes prone to star activity, consult the Roche Restriction Enzyme Poster (or the Roche Applied Science Catalog) to select the optimal buffer for a given enzyme combination. Whenever possible use Buffer H for double digests. Application The Rapid DNA Ligation Kit covalently joins either stickyended or bluntended DNA fragments, for example, for Cloning into plasmid or phage vectors. Adding linkers to plasmids or other DNAs. Recircularizing linear DNA. Features and Benefits
