Agarose Pulsed-Field, ROTI®Garose, Genetic engineering quality, CAS No. [9012-36-6], EG-Nr. 232-731-8

Our agarose ROTI^®Garose is a neutral polysaccharide which is obtained in many purification steps from the cell wall of certain algae, called Rhodophyceae. ROTI^®Garose forms very clear gels with all standard running buffers and will result in a sharp and clear separation of your biomolecules. Extremely pure agarose with very low interference binding to staining reagents. ROTI^®Garose produces a low background and high contrast appearance after staining.

For clear and sharp bands
Gels with high transparency
Low background
Suitable for all standard running buffers and high-speed buffer systems
Compatible with all nucleic acid staining systems
Non-toxic in cell immobilisation assays
Of course DNase and RNase free

Agarose as Gelling Reagent

Chemically, agarose is a galactan which is capable of forming extremely solid gels, even at a low concentration. The pore size of the gels is determined by the concentration of the agarose used. Because there are no ionic groups in the gel, hydrophilic materials without any interaction with the gel matrix will also be separated according to their size. The high hysteresis of the agarose, that is the thermal stability after solidification, ensures that the gels remain reliably stable even during heatproducing running conditions.

Agarose Pulsed-Field ROTI^®Garose Genetic engineering quality, for pulsed field electrophoresis

Optimised for separation of fragments of 20 to 50 kb or for Pulsed Field Gel Electrophoresis (PFGE)
High gel-strength agarose for tearproof gels that are easy to handle
High DNA mobility for fast and efficient gel electrophoresis
Low background fluorescence after ethidium bromide staining
In general, suitable for separation of fragments larger than 1000 bp
Tested for absence of DNAses, RNAses and DNA binding

Toepassing

Separation of large fragments (from 20 kb), Pulsed Field gel electrophoresis (PFGE)

Electroendosmosis (EEO)

Osmotic Liquid Migration Caused by Electric Current

In gel matrices of agarose gels, minor impurities caused by cations (sulphate ester) are frequent. When an electric field is applied they move in the direction of the cathode, generating an electroosmotic flow (EOF) of the entire aqueous medium towards the negative pole. The migration speed of the flow depends, amongst other things, on the strength of the electric field and the frictional force generated by the gel matrix. The EOF always runs in the direction of the cathode, that is opposite to the movement of the anions separated during nucleic acid electrophoresis, and slows down their migration.

In the event of an agarose with high EEO, many cations are present, which generate a strong EOF. Furthermore, the gel strength is low, causing only weak frictional force. The strong EOF can lead to a change of behaviour during the run of the negatively-charged molecules (DNA/RNA) when using the agarose MEEO or HEEO. In extreme case anions with low self-mobility can even be diverted and transported in the direction of the cathode, causing band shifting.
