Publish, post, upload, distribute or disseminate any inappropriate, profane, defamatory, infringing, obscene, indecent or unlawful topic, name, material or 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) 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 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. DNA was purified using the QIAamp DNA Blood Mini Kit. When blood is stored at 4°C, the DNA is rapidly degraded due to apoptosis; the resulting apoptotic banding pattern can clearly be seen in these samples. M1: lambda-Hind III; M2:100 bp ladder.|Amplification of a 10 kb fragment of the human ALDH1 gene from genomic DNA isolated from blood. DNA was purified using conventional methods (Phenol) or the QIAamp DNA Blood Maxi Kit (QIAamp). PCR products were sequenced directly. M: 1 kb ladder.|Three paternity cases tested with DNA purified from blood samples with the QIAamp DNA Blood Mini Kit. 1: mother; 2: child; 3: alleged father; 4: child + alleged father. M: markers. Each lane had 3 µg of DNA loaded. Outcome: A: alleged father excluded; B & C: alleged father confirmed.

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.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. Optionally, repeat the elution step, and incubate the spin column on the bench for 10 minutes with RNase-free water before centrifuging. Where delivery or performance dates are stated by VWR these are estimates only and time is not of the essence; however, if VWR needs to change such dates it will do so only after providing information to the customer and having regards to the customer’s stated objectives.

If the cells in RNAprotect Tissue Reagent cannot be collected by centrifugation, please try one of the following suggestions: 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 rightsVWR 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 the total liability of VWR for any loss or damage suffered by a customer in connection with the supply of the products under this contract is limited to the invoice price of the products in relation to which loss or damage is claimed.

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. 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. 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.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.

In case crosslinking agents (e.g. formaldehyde or glyoxal-containing) were used for fixation of the tissue for cryosectioning the RNeasy FFPE Kit is the perfect choice. The RNeasy FFPE Kit is especially designed for purifying total RNA from formalin-fixed tissue sections. Special lysis and incubation conditions reverse formaldehyde modification of RNA for improved results in downstream application. The crosslinking causes the RNA to break, resulting in overall smaller molecules, which look like a smear when analyzed on a formaldehyde gel.Price on application’ (POA) quotations and all other quotations do not constitute offers and will be valid for 30 days from the date of the quotation, unless otherwise notified by VWR. 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.
