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 solidifi cation, ensures that the gels remain reliably stable even during heatproducing running conditions.

Add remaining buffer up to the desired final volume. Weigh and record the weight of of agarose and all components the flask prior to heating. Heat for 1 — 2 minutes in a microwave oven Watt. Gently swirl the flask to mix the solution. Warning: Due to microwave heating of puffer, there may be a delay in the liquid boiling!
Using the microwave oven, heat in short bursts of 5 — 10 seconds or until the solution with agarose is boiling, with breaks of 10 — 15 seconds between heating phases to disperse bubbles by gently swirling the flask.
Beware of hot glass ware and liquid. Continue until the agarose is completely dissolved. Again, weigh the flask and top up lost volume with warm, deionized water.
Gently swirl the flask to ensure complete mixing of agarose and all components. Method 2: Simmering water bath. Weigh and record the weight of the flask prior to heating. Heat agarose suspension up in a simmering water bath with constant stirring. Leave the flask of agarose and all components bath in the water for further 15 — 20 minutes, or until the agarose is completely dissolved. Switch off the magnetic stirrer and leave the flask with agarose in the bath for further 15 minutes.
Storage: can be stored at room temperature for more than 4 years. Dear customer, GeneON likes to send free samples for Agarose for Gelelektrophorese to convince the valued customer about the quality. Please understand that the shipping costs may be very high to some destinations. That is the reason why we cannot assure to fulfil all sample requests. Sorry for that, please understand. To make half-wave or full-wave rectified current is not so difficult. Figure 12 is a diagram showing full-wave rectification from alternating current.
Four diodes are needed in this diagram, and they are substituted by one Graetz bridge. A simple circuit diagram of full-wave rectification for agarose gel electrophoresis. A DIY power supply based on a diagram of Figure Figure 13 is an example of DIY power supply, which is based on the diagram of Figure Figure 14 is a close view of the same DIY power supply, in which only one Graetz bridge is used. A fuse is incorporated in this supply for safety.
A close view of the DIY power supply Figure An inexpensive Graetz bridge AM is used in the supply. In this manuscript, several technical tips for low-cost agarose gel electrophoresis have been described.
The key factor of the tips is agarose or agar selection, recycling of agarose, buffer selection, and DIY equipment. Several experiments need a step to recover and isolate fractionated DNA from the agarose gel.
In such cases, a high quality of agarose can affect the experiment. Nevertheless, such a high-quality agarose is not always needed for simply checking the band patterns of fractionated DNA. Agarose quality can be changed in its purpose, time, place, and occasion.
Agarose gel electrophoresis is a simple technique. Based on its principle, it can be modified and customized as how much cost you spend to the experiment. Moreover, technical tips described here do not mean downgrading of experiment quality; DNA can migrate and be fractionated as the same way as the standard protocol.
The important point is that a calibration test is needed at each reagent and equipment. In my experience, gel strength varies in each product, and concentration of the agar in the gel should be adjusted at each condition. In this manuscript, the topic has been focused into mainly DNA electrophoresis by agarose gel. RNA is far more sensitive to nuclease ribonuclease for ribonucleotides than DNA deoxyribonuclease for deoxyribonucleotides.
This also means that much higher quality of reagents is required for RNA electrophoresis, especially eliminating a contamination of ribonuclease.
Moreover, some special technique is required in RNA electrophoresis for denaturation of tertiary structure of single strand RNA. Even though there stand such points to take account of RNA, the buffer tank and power supply in this manuscript will also be able to work in RNA electrophoresis, because of the same principle of the electrophoresis of nucleic acids.
