How to Calculate the Required Synergel™ Quantity?

1. What percentage agarose gel is currently being used?

2. The gel will inevitably contain 0.7 % agarose (the minimum agarose concentration required to ensure gel stability). Hence, subtract 0.7 % from the agarose total.

3. Divide the difference by 2. The result is the percentage of Synergel™ to be added to the 0.7 % agarose.

Convert a 1 % agarose to a 1 % Synergel™/agarose gel

a. Substract 0.7 % from the 1 % agarose: 1 % - 0.7 % = 0.3 %

b. Divide the difference by 2: 0.3 % : 2 = 0.15 %

c. 0.15 % (150 mg / 100 ml) is the amount of Synergel™ added to 0.7 % agarose (0.7 g / 100 ml) to produce the functional equivalent of a 1 % agarose gel.

Synergel™ ≥99 %, for gel electrophoresis, up to 30 kb

Synergel™ is a synergistic gelling and sieving agent consisting of a modified polysaccharide which, when combined with agarose, forms a hydrogen bonded binary gel system.
The addition of Synergel™ to agarose improves gel performance by providing superior separation and definition of DNA fragments up to 30 kb. A gel mixture containing 0,7 % agarose and 0,7 % Synergel™, e.g., will produce improved results when compared to a 2 % agarose-only gel.
Synergel™ also provides greater optical clarity, which allows higher quality photodocumentation of stained gels.

Directions for use

Standard buffer systems like phosphate, acetate or borate buffered Tris-EDTA may be used in forming the gel with agarose/ Synergel™. RNA may also be separated in this system by using a 2,2 M formaldehyde-containing buffer. Synergel™ is compatible with standard blotting procedures, thus, nucleic acid may be electroeluted or transferred to membranes following standard Southern/Northern blotting protocols.

The figure compares separation qualities of
A: 1,5 % Synergel™ / 0,7 % agarose and B: 4 % high-resolution agarose (NuSieve®).

General information

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.
