Nucleic Acid Purification

AquaGenomic™

Highest yields and purest total DNA in just 1 hour

Overview

AquaGenomic™ is a novel, nontoxic and multifunctional aqueous solution for the isolation
and purification of genomic DNA. The patent pending technology allows the completion of
cell suspension, cell lysis, DNA extraction and debris removal using a single aqueous solution!

Features:

• It's different
  Isolation and purification is based on selective extraction in aqueous solution instead of binding to solid support.
  
• It's simple
  Cells are lysed, genomic DNA is extracted, and cell debris is precipitated in a single step using one aqueous solution, before purified genomic DNA is precipitated with isopropanol.
  
• It's easy
  No columns, no resins, no slurries, no beads, no filters, no membranes, no needles, no cartridges, no manifolds, no HPLC.
  
• It's scalable
  One single AquaGenomic™ solution does all: mini, midi, maxi and 96-well preps.
  
• It's flexible
  Genomic DNA can be isolated from cultured cells, buccal swabs, microbes, blood, saliva, stool or various animal or plant tissues using the same AquaGenomic™ Solution.
  
• It's fast
  Less than 20 minutes from cells or tissues to pure genomic DNA.
  
• It delivers pure DNA
  Excellent purity - suitable for all common applications.
  
• It delivers high yield
  Excellent quantities of 5-10 µg DNA from 1-2 mio. cells, 200 µl of whole blood, 15 mg of feces, 1 ml bacterial culture, 5-10 mg of animal tissue, or 10-20 mg of plant tissue.
  
• Its economic
  AquaGenomic™ Solution is priced about 1/4 compared with other genomic DNA isolation kits - that’s 85 ct per mini prep!

AquaRNA™

A novel aqueous solution-based technology for isolation and purification of RNA

AquaRNA™ is a multifunctional aqueous solution for DNA, RNA, and protein extraction. It functions to lyse the cells, inactivate RNases, and extract DNA, RNA, and proteins. DNA and RNA are readily recovered from the lysate by isopropanol precipitation, while proteins remain in the supernatant and can be recovered by acetone precipitation. It allows you to isolate DNA, RNA, and proteins for analyses from the same cells, tissue, or organism. Additionally, AquaRNA™ can be used to inactivate and remove contaminating RNases in purified RNA samples to ensure RNA integrity and stability.

Features:

• Concept-Changing
  AquaRNA™ will change the way you think and work with RNA by simply inactivating and removing endogenous contaminating RNases in your purified RNA samples.
  
• "RNA is very unstable, labile, and must be stored at -80 °C." - This is a misconception. If endogenous contaminating RNases are removed, RNA samples can be stored at 4 °C or even room temperatures for months without degradation.
  
• "We buy and use only RNase-free consumables." - This is a waste of money. If RNA is not contaminated with endogenous RNases, your chance of getting RNA degradation by using regular reagents, solutions, tubes, and tips is very slim.
  
• "RNA work must be done at designated RNA-only workbench and use RNA-only equipment." - This is again a waste of resources. Just don't let your fingers, with or without gloves, touch the inside of your RNA tube and its lid, you will be fine. "I am always anxious until I see the results of my RNA experiments." - If the RNA is not contaminated with residual RNases, you will find that RNA is no longer difficult to work with and you will get consistent and reproducible results.
  
• RNase Decontamination
  AquaRNA™ can be used to treat purified RNA that is contaminated with RNases. It can also be used to treat plasmid DNA or in vitro transcribed RNA to remove any contaminating RNases to ensure successful in vitro transcription and translation reactions.
  
• Not only for RNA
  AquaRNA™ can extract DNA, RNA, and proteins from the same biological samples. If you are comparing two genomic profiles, such as normal vs. tumor tissues, why not compare their RNA expression profiles, and further, their protein expression profiles as well? In addition to maximizing the value of your invaluable samples, you might uncover new correlations and new differences.
  
• Simple
  Due to the multifunctionality of the AquaRNA™ solution, its protocol is very simple. After cell lysis, DNA/RNA are precipitated with isopropanol leaving proteins in the supernatant.
  
• Easy
  No columns, no resins, no slurries, no beads, no filters, no membranes, no needles, no cartridges, no manifolds, no HPLC, no ultracentrifuge.
  
• No Nasty Organic Solvents
  AquaRNA™ extracts DNA/RNA/proteins much like the famous Trizol^® (Invitrogen), but is much simpler and requires no phenol and no chloroform. Yes, it contains guanidine thiocyanate.
  
• Scalable
  One single AquaRNA™ Kit does all: mini, midi, maxi, and HTP; no need to purchase separate mini, midi, maxi, and HTP kits. High yield up to 100 ug of DNA, 50 ug of RNA, and 2000 ug of proteins can be isolated from 5 million mammalian cells or 50 mg animal tissue.
  
• Economic
  AquaRNA™ kit is priced at 199 €/kit for 300 minipreps, that is 0.66 €/miniprep or approximately 1/6 the price of other RNA isolation kits. Each miniprep uses 100 ul AquaRNA to extract DNA/RNA/proteins from 1 million cells.

For rapid isolation of DNA and for essential purification steps these kits can be used in the determination of gene expression or polymorphisms in metabolic or genetic hereditary diseases. The application of beads for isolating DNA from cells needs to wash-out bound DNA, which can be done by different principles.
Recent tests demonstrated that the M-Beads DNA can be used with buffers from other suppliers.

M-Beads Magnetic silica beads DNA are specifically designed for nucleic acid isolation for rod type robotic systems.
M-Beads Magnetic silica beads DNA allround have high magnetic content optimized for nucleic acid isolation from various sources (blood, cells, bacteria etc.) for robotic and manual workflow.
M-Beads Magnetic silica beads DNA COOH are especially developed for nucleic acid isolation for rod type robotic systems. The carboxylated surface guarantees best results in terms of DNA purity and yield. They are recommended for high DNA yield applications like isolation of viral DNA, DNA sequencing or PCR clean up.
M-Beads Magnetic silica beads DNA allround COOH with their high magnetic content are optimal for high DNA yield applications for robotic and manual workflow.

Different applications, interests and needs cannot be matched with one single method or with one single magnetic silica bead. High throughput applications supported by robotic liquid handling stations typically take advantage of magnetic beads with strong magnetic response, whereas highly complex, manual DNA extraction procedures need magnetic beads with highest DNA capture, DNA selectivity and lowest unspecific binding. The following tables will help you choosing the best solution for your needs.

NuClean Silica Matrix DNA Purification

Features:

• Yields highly purified DNA
  
• Time-saving, easy protocol
  
• Exceptionally low price

Product Description:

NuClean is a quick and efficient system for the purification of single- and double-stranded DNA from solutions and agarose gels. The method is based on the high affinity of nucleic acids to the large surface of the silica particles in the presence of a chaotropic salt. After two washing steps, the purified DNA can be eluted quantitatively in a small volume of water or TE buffer. No further purification is required for subsequent enzymatic procedures. Since DNA fragments <40 bp in size do not bind to the particles, it is possible to separate DNA products from non-incorporated nucleotides and oligonucleotides. Striking features of NuClean are high purity of the nucleic acid product, minimal time needed for the procedure (<20 minutes) and an exceptionally low price! The product yield is between 60 and 80%. One NuClean kit is sufficient for 400 purifications from TAE gels or 300 purifications from reaction solutions. NuClean II comes with an additional modification solution that allows the purification of DNA from TBE gels.

Applications:

• Isolate DNA fragments from TAE or TBE gels
  
• Purify DNA from non-incorporated nucleotides and oligonucleotides
  
• Quickly purify and concentrate your PCR products
  
• Purify plasmids from bacterial lysates
