The peqGOLD DNase I Digest Kit is optimised for use with peqGOLD RNA extraction protocols. Normally DNase I digestion is not required for RNA purified with peqGOLD RNA Mini Columns as our silica-based spin column technology efficiently removes the majority of DNA without enzymatic digestion. However, certain sensitive RNA applications may require further DNA removal.

Powerful electronic stirrers that feature a smooth start operation which prevents spills and splashing media. The speed ramps up slowly until set speed has been reached. Both models feature safe start and stop of operation via an intuitive glass slide touch panel to avoid accidental start-up. An overtemperature sensor shuts off the unit in dangerous heat-up situations, ideal for unattended continuous operation. All units are designed for continuous 24-hour operation, including challenging high viscosity applications in polymer research. High torque levels give better mixing results in less time, maintenance-free motors reduce repairs and down time. Hei-TORQUE Value 400 and Hei-TORQUE Precision 400 units have two speed gears.

Agarose is a natural polysaccharide isolated from agar or agar-bearing marine algae. Its physical and chemical properties are particularly suited for use as a gel medium for diffusion and electrokinetic movement of biomolecules. Agarose is essentially biologically inert and forms relatively clear, transparent gels. Agarose based gels offer several advantages: High gel strength permits use of low concentrations. The macroporous nature of the gels allows rapid diffusion of high molecular weight molecules. Agarose is Non-toxic. Agarose gels are thermally reversible facilitating sample recovery. Staining and destaining may be done rapidly with minimal background. Because agarose forms macroporous gels that are electrically nonionic, it is an excellent medium for Isoelectric Focusing (IEF). A selection of different formulated agaroses with specific qualities for unique applications are available from MP.
Multipurpose Agarose is a versatile high gel strength agarose, especially designed for a wide range of molecular biology techniques. It is used for resolution of fragments over a large size range from 200 bp up to 50 kb by conventional electrophoresis. It is suitable for use in pulsed field gel electrophoresis and for blotting assays.
High gel strength agarose, especially designed for a wide range DNA. Versatile – separate fragments from 200 bp up to 50 kb by conventional electrophoresis. Concentrations between 0.4% and 6%. Multipurpose Agarose features the highest gel strength available, allowing 0.4 - 0.5% agarose gels. Significantly decreases electrophoresis times. Improves separation of very large fragments. Dissolves easily in a microwave.
