Product Information

Any additional or special terms included by VWR in its written acceptance shall form part of the contract. The terms and conditions of the contract apply equally to the supply of both products and services except where application to one or the other is specified. ensure complete disruption and homogenization of the starting material as instructed in the section 'Disruption and homogenization of starting materials' of the handbook RNeasy Kits are the Gold standard for total RNA isolation. They provide fast purification of high-quality RNA from small to large amounts of cells, tissues, and yeast using silica-membrane RNeasy spin columns or 96-well plates. Tissue samples can be conveniently stabilized using RNAprotect Tissue Reagent or Allprotect Tissue Reagent, and efficiently disrupted using a TissueRuptor II or TissueLyser II or LT system. The RNeasy 96 Kit enables high-throughput purification of total RNA from up to 96 cultured-cell samples using silica-membrane RNeasy 96 plates. A dedicated RNeasy QIAcube Kit enables automated purification of 1–12 samples on the QIAcube Connect.

If cells are floating on the surface of the RNAprotect Tissue Reagent, try removing the reagent by pipetting from underneath. Leave behind approximately 100 ul of RNAprotect Tissue Reagent, and add 350 ul Buffer RLT before proceeding with the protocol "RNeasy Mini Protocol for Isolation of Total RNA from Animal Cells". For every 100 ul of cells in RNAprotect Tissue Reagent, use 250 ul of 96-100% ethanol instead of the 70% ethanol listed in step 4 of thestandard protocol. In addition, tissue/cell lysis steps are typically carried out with lysis buffers containing guanidine isothiocyanate, a potent protein denaturant. It is very important to use a sufficient amount of lysis buffer during RNA isolation. We recommend using at least 10x volume of lysis buffer to tissue/cell pellet.The customer shall cooperate with VWR in all matters relating to the services, provide all such access and information as is necessary and obtain any licences permissions and consents required before commencement of the services. RNeasy technology simplifies total RNA isolation (see table “Amount of starting material for RNeasy procedures”). Samples are first lysed and then homogenized. Ethanol is added to the lysate to provide ideal binding conditions. The lysate is then loaded onto the RNeasy silica membrane and RNA binds to the silica membrane, and all contaminants are efficiently washed away. For certain RNA applications that are sensitive to very small amounts of DNA, the residual amounts of DNA remaining can be removed using a convenient on-column DNase treatment. Pure, concentrated RNA is eluted in water. A variety of special application protocols is also available. VWR shall under no circumstances whatsoever be liable to the customer (whether in contract, tort (including negligence), breach of statutory duty or otherwise), for any loss of profit, or any indirect or consequential loss arising in connection with the supply of products under this contract; and

All intellectual property rights arising out of or in connection with the services shall be owned by VWR. Termination The PureYield™ Plasmid Maxiprep System purifies up to 1mg of transfection-quality plasmid DNA from 250ml bacterial cultures in under an hour. The system is designed for use with a vacuum source and vacuum manifold, greatly reducing the time spent on purification compared to silica resin or other membrane-based methods. An example of the calculations involved in RNA quantification is shown below. Use the buffer in which the RNA is diluted to zero the spectrophotometer: The PureLink™ HiPure Plasmid DNA Purification Kits use a patented anion-exchange resin to purify plasmid DNA to a level equivalent to two passes through CsCl gradients. The resin combines excellent capacity with a fast flow rate, high resolution, high yield, and efficient endotoxin removal. Plasmid preparations can typically be completed in less than 2 hours.Optionally, repeat the elution step, and incubate the spin column on the bench for 10 minutes with RNase-free water before centrifuging.

Any liability accepted by VWR under this contract is in lieu of any terms implied by law as to the quality or fitness for any particular purpose of the products and/or the standard of the services and all such implied terms are, to the fullest extent permitted by law, excluded from the contract between VWR and the customer. The customer shall indemnify VWR against any claims made against VWR by the customer’s employees, contractors or agents. Intellectual property rights The customer is required to ensure that the use of any products supplied by VWR does not infringe the intellectual property rights of any third party and the customer shall indemnify VWR against any claims made against VWR by any third party in relation to any such infringement or alleged infringement. Authorisation to return products damaged during delivery must be requested within 3 days of delivery. VWR has the right to repair and return damaged products. Products are scored from 1 to 10 except for energy and water consumption, which are scored as 1 point per kWh or gallon, respectively. A low score means a lower environmental impact (see figures "RNeasy Mini Kit ACT environmental impact factor label US, EU and UK" Add 600 µl Buffer RLT to a maximum of 200 µl sample volume, and proceed with step 3 of the "RNeasy Mini Protocol for Isolation of Total RNA from Animal Cells" in the RNeasy Mini Handbook . Load the lysate onto the column in successive aliquotsin step 5 of the protocol.

The dedicated RNeasy Mini QIAcube Kit, including rotor adapters preloaded with RNeasy spin columns and elution tubes, delivers greater convenience and time savings (see figure "Significant time savings with dedicated QIAcube Kits"). Low yields of plasmid DNAcan be caused by a number of different factors. The most common causes for low yield are poor culturing conditions and plasmid propagation, excessive amounts of starting material resulting in insufficient bacterial celllysis and column overloading. When working with the anion-exchange based QIAGEN Plasmid Purification Kits, extra care is required during the isopropanol precipitation step, as the glassy DNA pellet may be difficult to see, and tends to be only loosely attached to the side of the tube. Note that the A260/A280 ratio is influenced considerably by pH. As water is unbuffered, the pH and the resulting 260/280 ratio can vary greatly. For an accurate determination of purity, we recommend measuring the 260/280 absorbance in 10 mM Tris-Cl, pH 7.5. Be sure to calibrate the spectrophotometer with the same solution. Pure RNA has an A260/A280 ratio of 1.9-2.1. However, values up to 2.3 are routinely obtained for pure RNA (in 10 mM Tris, pH 7.5) with some spectrophotometers. prevent overloading by adjusting the amount of starting material tono more than the maximum amounts recommendedin the RNeasy Mini Handbook Authorisation for the return of products which fail to meet current published manufacturer’s specifications must be requested in writing within 28 days of delivery. VWR will assist customers, at customers’ expense, to obtain any manufacturer’s warranty consistent with that granted to VWR.
