Loading buffer is optional. Samples can be loaded directly into the wells if no buffer is used, or you can dilute them with deionized water or TE buffer. If you want to use a loading buffer, please see the recipes below:
E-Gel agarose gels (including EX)
10 mM Tris-HCl, pH 7.5
1 mM EDTA
0.005% bromophenol blue
0.005% xylene cyanol FF
E-Gel CloneWell II and E-Gel SizeSelect II agarose gels
10 mM Tris-HCl, pH 7.5
1 mM EDTA
Alternatively, you can use 10X BlueJuice Gel Loading Buffer or TrackIt Loading Buffer. Dilute this buffer 50- to 200-fold to obtain optimal results with E-Gel agarose gels.

Our E-Gel agarose gels can be used for either DNA or RNA separation. RNA separation occurs under non-denaturing or denaturing conditions. Please note, our gels are not QC tested for the presence of RNases. See our suggestions below for running your non-denaturing or denaturing samples:
Non-denaturing conditions
1. Mix RNA sample with 15 µL of RNase-free water.
2. Do not heat. Load the entire sample onto the E-Gel agarose gel.
3. Electrophorese for 30 min.
Denaturing conditions
1. Mix 15 µL of RNA loading buffer with 1-5 µL of RNA (1-5 µg).
2. Heat samples at 65 degrees C for 10 min to denature RNA.
3. Place samples on ice immediately after heating.
4. Load entire sample onto E-Gel agarose gel.
5. Electrophorese for 30 min.
Note:
- The only denaturing agent that is compatible with the E-Gel system is formamide, 50-95%. Heating the sample for 5 min at 65 degrees C should be sufficient for denaturing. Using other denaturing agents like glyoxal, formaldehyde, or urea will result in very poor separation and band morphology on E-Gel agarose gels.
- Additionally, we do not recommend running samples with RNA loading buffer on the same gel as samples loaded with water.
- E-Gel EX Double Comb agarose gels and E-Gel Double Comb agarose gels with SYBR Safe stain have not been tested for use in RNA applications.

To create a bufferless system, each E-Gel cassette contains two unique ion exchange matrices that lie between the running gel and the electrodes. The ion exchange matrices provide a buffer-ion reservoir that supplies a continuous flow of Tris, acetate, and dye ions throughout the gel. This patented technology results in a sustained electric field with enhanced buffering capacity. E-Gel gels thus eliminate the need for you to prepare and dispose of liquid buffer, thus saving time and waste.

The E-Gel agarose gel system is a precast bufferless TAE system that uses ion exchange matrices. The gels themselves are enclosed within a semi-UV-transparent cassette. This patented technology results in a sustained electric field with enhanced buffering capacity. E-Gel gels thus eliminate the need for you to prepare and dispose of liquid buffer, thus saving time and waste.

E-Gel agarose gels are routinely used in-house in R&D and manufacturing for RNA analysis with excellent results. However, the gels are not guaranteed to be “RNAse-free”. The manufacturing process is designed to avoid contamination of any type, but not RNAses specifically.
If you do want to try it, any loading buffer that would be used for non-denaturing RNA electrophoresis should be fine for E-Gel agarose gels. Depending on your application, these gels may or may not be suitable for use.

Several advantages of the E-Gel 96 are listed below:
1. They are pre-cast - no gels to pour.
2. They are bufferless - no buffers to prepare or dispose; no mess to clean up.
3. They are pre-stained - no staining/destaining procedures, no handling of toxic staining agents.
4. Bases are SBS (Society for Biomolecular Screening) standard compatible for 96-well format - they fit most robotic platforms designed for standard microtiter plates.
5. Patented staggered-well format offers double the run length per sample compared to standard 96-well gels, while still remaining compatible with standard 8-, 12-, or 96-tip robotic loading systems.

Potential problems include:
- Loading too much DNA. Do not load more than the recommended amount.
- Samples with a high salt concentration. Samples containing > 50 mM NaCl, 100 mM KCl, 10 mM acetate ions, or 10 mM EDTA will cause loss of resolution.
- Samples may have been diluted in TAE instead of TE or water.
- Samples may have been pre-run; pre-running is not recommended for any of our E-Gel agarose gels.
- Sample was not properly loaded or had a very low volume of sample loaded. Load the recommended sample volume based on the gel type and loading method. For proper band separation, we recommend keeping sample volumes uniform.
- Bubbles may have been introduced while loading the samples. Bubbles will cause band distortion. Load deionized water or TE into any empty wells, and avoid introducing bubbles.
- A longer electrophoresis run time was used. Do not run the gel longer than the recommended time for each gel type. Longer run times cause an increase in the current, resulting in poor band migration or a melted gel. We recommend that you run single comb gels for 25-30 min (double comb gels 15-20 min) for straighter patterns. Do not run single comb gels longer than 40 minutes (20 minutes for double comb), or the gel will be damaged and resolution will be poor.
- Voltage or current too high. This should not be an issue with the E-Gel PowerBase power supply, which is pre-set with the proper conditions. However, researchers using the old E-Gel Base (the one that plugged into a separate power supply) should ensure that they run the gel at 60 to 70 volts (constant voltage) or 40-50 mA (constant current). Do not allow the current to exceed 60 mA.
- For E-Gel 96 Agarose Gels being run on an E-Base device, be sure you are running on the “EG” program rather than the “EP” program designed for E-PAGE gels.
- The gel was not electrophoresed immediately after sample loading (for best results, run gel within 1 min of loading).
- The gel may have been used beyond its expiration date. Check the expiration date.

No. Standard safety and hazardous waste disposal procedures should be followed when handling E-Gel EX agarose gels.
E-Gel EX agarose gels separate DNA faster, offer enhanced sensitivity, and provide added flexibility. The stain within the E-Gel EX agarose gels is SYBR Gold II which has similar spectral properties but increased sensitivity compared to SYBR Safe DNA Gel Stain. E-Gel EX agarose gels are especially suited for applications where high sensitivity is critical.
No. E-Gel agarose gels have enough buffering capacity for one run only. Performance will be impaired with multiple runs.
