Page 9: Mini Submarine Electrophoresis Unit Function
Mini submarine electrophoresis unit function ® The Hoefer HE33 horizontal agarose unit is intended for rapid electrophoresis of small quantities of nucleic acids in agarose gels. A gel is cast in the gel caster, which holds one or two combs. (Eight different combs are available;... -

Page 11: Operating Instructions
Operating instructions Agarose gels are first prepared using the gel cast- ing kit. Samples are then loaded into wells and electrophoretically separated. The fluorescent dye ethidium bromide can be added to the gel or electrophoresis buffer or both to track separa- tion progress. - Page 12 Prepare solutions Prepare 250 ml of running buffer. (Refer to page 12 for recipes of commonly used electrophoretic running buffers.) Caution: Ethidium bromide is a known mutagen. Always wear gloves when handling. Prepare the sample loading buffer. (Refer to page 14 for a recipe and a table of volume requirements for each comb size.) ...
- Page 13 Cast the gel Install the running tray Firmly grasp the casting tray with one hand. With the other hand, place one end of the running tray against the foam pad at the bottom edge, press the tray against the pad, and then lower it to rest on the bottom of the casting tray, seating the other end of the tray against the opposite foam pad.
- Page 14 Once the gel is set, remove the comb carefully. Partially lift and slightly tilt the comb at one end and then slowly withdraw it from the gel. (Pulling the comb straight up creates a vacuum in the wells that may lift the gel out of the tray.) ...
- Page 15 The electrophoresis run Refer to the notes, buffers, and volumes section for additional information and guidelines. Chill the base before use, especially when higher voltage settings will be used or when the separation will require more than 30 minutes. Note: To monitor separation progress, either add 0.5 µg/ml (final conc.) of ethidium bromide to the running buffer now, or add 50 µg/ml (final conc.) ethidium bromide to the sample buffer.
- Page 16 Quick, high-voltage runs Certain applications, such as screening samples or checking sample purity, can be accomplished quickly under high voltage conditions. Chill the base (-20 °C) and limit the run to 5 minutes or less at 500 V. Slower, lower voltage runs A voltage gradient of 12 V/cm (150 V) separates 0.1 Note: To calculate the voltage gradient, divide the voltage to 23 kb fragments of a Hind III digest of λ...

Page 18: Troubleshooting
Troubleshooting problem solution Deformed sample well Allow the gel to set for a minimum of 30 minutes and make sure it is at room temperature before removing the comb. When removing the comb, hold it at a slight angle and lift very slowly to prevent the gel from breaking. Take care to not damage the well with the pipet while loading the sample;... -
Page 19: Notes, Buffers, And Volumes
Notes, buffers, and volumes Agarose gel electrophoresis notes Agarose gel electrophoresis can be used to sepa- rate DNA fragments as small as 0.1 kb or less. Polyacrylamide gels are usually used for frag- ments smaller than 1 kb. DNA mobility Suggested agarose concentration for separating fragments of various sizes is given in Table 2 below. - Page 20 RNA samples usually require longer runs or buffers that are easily depleted, and so require circulation. The Hoefer SUB20C and SUB25C horizontal units are recommended for this appli- cation rather than the HE33. Running buffers for DNA in agarose gels...

DNA detection DNA can be detected either by the fluorescence of bound ethidium bromide or by autoradiography of radiolabeled DNA. Ethidium bromide (0.5 µg/ml) can be added to running buffer to monitor sample progress because Caution! Ethidium bromide is the dye’s fluorescence under a UV lamp reveals a known mutagen. -
