Dialysis Tubes

While working with proteins and nucleic acids, it is very often necessary to eliminate small molecular weight substances such as reducing agents [dithiothreitol (DTT), 2-mercaptoethanol (BME), urea], un-reacted crosslinking or labeling reagents (sulfo-SMCC, biotin) and preservatives (sodium azide, thimerosal) that might interfere in subsequent steps of the experimental protocol. Methods such as dialysis and electro-elution (for extraction of nucleic acids from gels) have long been used to purify proteins and nucleic acids. However, these traditional methods are riddled with numerous problems which may lead to tremendous time consumption, sample loss, contamination and high sample dilutions requiring further concentration.

BioVision’s DiaEasy™ Dialyzer tubes product line offers a solution to most of these issues. Our Dialysis tubes come in easy to use sets of 10, 25 and 100 tubes each, catering to different molecular weight cut-offs of 1 kDa, 3.5 kDa, 6-8 kDa, 12-14 kDa, 25 kDa and 50 kDa for different sample volumes ranging from 10 µl to 20 ml. These sets also contain floating racks and/or supporting trays for convenient handling of the tubes in the exchange buffer and electro-elution. The combination of DiaEasy™ Dialyzer tubes and the electro-elution accessories provides a unique tool for extraction of any protein, protein-protein, or protein DNA complexes from non-denaturing and denaturing (SDS) polyacrylamide gels, and for extraction of oligonucleotides, RNA, and DNA from both polyacrylamide and agarose gels. The DiaEasy™ tube’s membranes are ultra-clean, sulfur and heavy metal free and EDTA treated which makes the harvested proteins and nucleic acids suitable for molecular biology experiments. These DiaEasy™ tubes allow rapid, secure and simple loading and recovery. They are very high performance dialysis tubes and are the most convenient, user friendly dialysis system on the market.
