Product Information

strictly follow the protocol for on-column DNase Digestion in Appendix D of the RNeasy Mini Handbook (you can let wash buffer RW1 incubate on the column for 3-5 minutesbefore centrifuging to enhance removal of excess gDNA prior to applying the enzyme) Most cryosections are fixed using non-crosslinking agents. For isolation of RNA from tissue embedded in Tissue-Tek O.C.T. using non-crosslinking agents the RNeasy Plus Micro Kit or the RNeasy Micro Kit (Protocol: Total RNA Isolation from Microdissected Cryosections), or the RNeasy Mini Kit (RNeasy Mini Protocol for the isolation of Total RNA from Animal Tissue) give great results. We strongly recommend removing as much of the embedding compound as possible prior to RNA extraction from the sections. Please see QIAGEN News article, Issue 1 1998,' Effects of malnutrition on expression of lactase in children' for successful RNA isolation from O.C.T.-embedded tissue using the RNeasy Mini Kit. Purity of RNA isolated with RNeasy Kits can be evaluated bydetermining the ratio ofabsorbance readingsat 260 nmand 280 nm (A260/A280). This ratio provides an estimate of the purity of RNA with respect to contaminants that absorb in the UV range, such as protein.

These terms and conditions cover all sales of products and services by VWR International Ltd (VWR) in the United Kingdom and any information and advice given whether charged for or not, unless otherwise agreed by VWR in writing. These terms and conditions apply to the exclusion of any other terms submitted by the customer or which are implied by any trade, custom, practice or course of dealing. Customer Accounts 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: In the rare case that trace amounts of genomic DNA are still detectable in sensitive downstream applications such as e.g.,realtime RT-PCR, an in-solution digest using the RNase-Free DNAase set can be performed. Instructionsare presentedin Appendix C of the RNeasy MinElute Cleanup Handbook. Find out which origin of replication your plasmid contains, andlook at the table below for classification into high-copy or low-copy types. This table can also be found online atthe QIAGEN Plasmid Resource Centerin the section' Growth of bacterial cultures; Plasmid Copy Number' .A way to determine experimentallyif the copy number of your plasmid is high or low is to perform a miniprep. A high-copy plasmid should yield between 3-5 ug DNA per 1 ml LB culture, while a low-copy plasmid will yield between 0.2-1 ug DNA per ml of LB culture. Dilute the sample 10x by adding cold PBS. Pellet cells by centrifugation.Caution: Cells might lyse.

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. On termination of the contract for any reason the customer shall immediately pay to VWR all of its outstanding unpaid invoices and interest. Confidentiality Toensure efficient gDNA removal when doing an on-column digest using the RNase-Free DNase Set in combination with RNeasy Minithe following factors are crucial: 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 VWR may at any time, without limiting any other rights and remedies that it may have, set off any amount owing to it by the customer under the contract against any amount payable by VWR to the customer (whether under the contract or a separate agreement). Delivery

For very low-copy plasmids, expected yields are 20–100 µg for the QIAGEN-tip 100, and 100–500 µg for the QIAGEN-tip 500. 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. 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 QIAamp DNA Blood Kits yield DNA sized from 200 bp to 50 kb, depending on the age and storage of samples (see figure " Apoptotic banding in stored blood"). The purified DNA is suitable for long-range PCR amplification (see figure " Long-range PCR") and restriction fragment length polymorphism (RFLP) analysis used, for example, for paternity testing (see figure " Paternity testing by RFLP analysis").

Protocols

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.

The QIAcube Connect uses advanced technology to process QIAGEN spin columns, enabling seamless integration of automated, low-throughput sample prep into laboratory workflows. All steps in the purification procedure are fully automated — and up to 12 samples can be processed per run. The QIAcube Connect together with the dedicated RNeasy Mini QIAcube Kit provides fast, easy, and convenient RNA purification. 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 level of endotoxin contamination in purified plasmid DNA depends on the purification method used (see table "Endotoxin levels in plasmid preparations"). Silica-slurry–purified DNA exhibits extremely high endotoxin levels. QIAGEN, QIAfilter, and HiSpeed Plasmid Kits and 2x CsCl ultracentrifugation yield very pure DNA with relatively low levels of endotoxin. EndoFree Plasmid Kits include an integrated endotoxin-removal step to yield plasmid DNA containing <0.1 EU/µg plasmid DNA. 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 Optimized buffers lyse samples, stabilize nucleic acids, and enhance selective DNA adsorption to the QIAamp membrane. Alcohol is added and lysates loaded onto the QIAamp spin column. Wash buffers are used to remove impurities and pure, ready-to-use DNA is then eluted in water or low-salt buffer. |Genomic DNA from 8 blood samples stored at 4°C for 1 week.

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" If the cells in RNAprotect Tissue Reagent cannot be collected by centrifugation, please try one of the following suggestions: The PureLink™ HiPure Plasmid Maxiprep Kit is designed to isolate transfection-grade plasmid DNA from E. coli. The Maxiprep Kit protocol will typically yield 500–850 µg plasmid DNA from 100–200 mL bacterial culture, at a purity that is comparable to that achieved by two passes through cesium chloride gradients.

CompactPrep Plasmid Kits enable fast, large-scale plasmid purification. The use of a vacuum manifold allows up to 24 samples to be purified in parallel on a single workbench (see figure "Microcentrifuge column format") for plasmid midi and plasmid maxi preps. Up to 200 µg plasmid DNA is purified in less than 60 minutes from 25 ml (high-copy plasmids) or 50 ml (low-copy plasmids) LB medium using the CompactPrep Plasmid Midi Kit. DNA is eluted in 100 µl and concentrations are typically 1–2 µg/µl. The CompactPrep Plasmid Maxi Kit enables purification of up to 750 µg plasmid DNA in less than 60 minutes from 100 ml (high-copy plasmid) or 250 ml (low-copy plasmid) LB medium. DNA is eluted in 200 µl and concentrations are typically 3–4 µg/µl. CompactPrep Plasmid Kits provide molecular biology grade plasmid DNA with low endotoxin levels (see figure "Low endotoxin levels"). QIAamp DNA Blood Maxi Kit yields up to 95.8% recovery of DNA, depending on the starting cell densities (see table). In view of the wide range of uses of chemicals and apparatus, the customer will be solely responsible for determining the suitability and specification of products, services, information and advice for its purposes.Authorisation will be subject to the condition that the products are returned to VWR Customer Service Centre or to the manufacturer or other source and by the method advised by VWR. Total RNA purified with the RNeasy Maxi Kit is of high quality and is suitable for many downstream applications (see figure "High-quality RNA from a variety of samples"). Total RNA is easily purified with the RNeasy Maxi Kit from large amounts of starting material including animal or human cells, animal or human tissues, and yeast cells (see table “Total RNA yields obtained with RNeasy Kits”). 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.
