CTAB DNA Extraction Buffer

Polysaccharides are problematic contaminants associated with DNA isolated from plants, because they can interfere with manipulations of DNA following isolation.
The ready-to-use buffer contains the non-ionic detergent Cetyltrimethylammonium-bromide (CTAB). Polysaccharides and DNA have different solubilities in CTAB depending on the concentration of sodium chloride. At higher salt concentrations, polysaccharides are insoluble, while at lower concentrations DNA is insoluble.  Consequently, by adjusting salt concentration in lysates containing CTAB, polysaccharides and DNA can be differentially precipitated.

The BioDrop Family for micro-volume measurement

Whatever your application — you can rely on the BioDrop range of instruments for rapid, simple and accurate measurement of your DNA, RNA, oligos and protein concentration and purity. BioDrop's fresh new approach has resulted in a range that is flexible when you require it, fast when you need it, and easy-to-use in every case.
The built-in sample port uses no moving parts. This meams that the instrument provides excellent reproducibility without the need to recondition or calibrate. Measurements are also highly accurate because the pathlength of the port is highly specified to +/- 5 µm.

Accuracy, robustness and ease of use are the hallmarks of BioDrop products.


BioDrop DUO

BioDrop µLITE – The choice for life scientists for whom speed and accuracy in micro-volume measurement are required, rather than a broad measurement range
BioDrop DUO – The ideal solution for those where flexibility of measurement is the key
BioDrop TOUCH – A UV/VIS spectrophotometer ideal for use with BioDrop CUVETTEs
BioDrop CUVETTE – The revolutionary micro-volume device is an accurate and robust tool for measurement of DNA, RNA, oligos and protein. For the use with BioDrop DUO and BioDrop TOUCH as well as for all UV/VIS spectrophotometers with beam heights of 8.5 mm and 15 mm.
BioDrop Resolution Life Science PC Software – A powerful analysis software that is included with all instruments

  • Non-corrosive, non-carcinogen
  • Easily sprayed on all surfaces without leaving any traces


Removal of DNA is very important especially on PCR work places to avoid cross-contamination between samples leading to inaccurate data. DNADecon completely destroys and removes DNA and RNA molecules from any surface making it ideal for decontamination prior to PCR reactions. It can be used for decontamination of all surfaces and equipment like electrophoresis chambers, pipettes, reaction tubes etc..

  • Ready-to-use, non-alkaline and non-carcinogenic
  • Complete removal of DNA and RNA
  • Easily sprayed on all surfaces without leaving any traces

• Easily inactivated and removed
• Unsurpassed stability, can be stored up to 1 year at room temperature

Cyanase™ Inactivation Resin
Highly specific Cyanase inhibitor protein coupled to Sepharose Fast Flow resin creating a novel method for inactivating and removing the Cyanase enzyme.
No more worries about downstream contamination with nucleases or difficult removal processes which may compromise product integrity.
• Removal of Cyanase Nuclease simple and easy in as little as 20 min
• No optimization needed
• Active over a wide range of conditions
• No interactions with other proteins or targets
• Extremely tight interaction between Cyanase and resin

Benzonase = trademark of Merck KGaA, Cyanase = trademark of RiboSolutions, Inc.

Salt Active Nuclease

The only endonuclease with an optimum activity in 0.5 M NaCl and significant activity at low temperatures


Salt Active Nuclease is a highly active non-specific endonuclease from a marine bacterium that cleaves both DNA and RNA.
• Works well in traditional protein buffer systems

New Application Note:
ICPL™ - Coupled Immunoprecipitation

ImmunoPrecipitation (IP) is widely used as a method to selectively isolate protein complexes from primary tissues. However, due to lack of specificity and selectivity of most antibodies and unspecific binding of the carrier beads, the method can produce false positives. The ICPL approach, employing stable isotope labelling and mass spectrometry, can discriminate true positive from false positive IP complexes.
