Western Blotting Electrophoresis Techniques

When running multiple gels in parallel, use of constant voltage is often preferred because a single voltage can be specified that is independent of the number of gels run in parallel. Constant Current. If the current is held constant during a run, the voltage, power, and consequently the heat of the gel chamber increases during the run.

Electrophoresis Power Supplies

Some power supplies support outputs of up to 5,000 V, 500 mA, and 400 W, which allow them to be used for many high-voltage applications, even those with a low current (microampere) range. Such power supplies can be used in running vertical or horizontal gels for protein gel electrophoresis, nucleic acid gel electrophoresis, and DNA sequencing.

Lab 4: Gel Electrophoresis

Gel electrophoresis is a method of separating DNA fragments by movement through a Jello-like substance called agarose. Derived from a seaweed polysaccharide, agarose gels form small pores ... speed of movement: (i) the voltage of the electrical field, (ii) the concentration of agarose, and (iii) most importantly, the size of the DNA molecule.

the run, voltage will increase to satisfy the requirement V=IR. If a voltage limit is not set and a local fault condition occurs, such as a poor connection, the voltage will increase sharply to compensate for the very local high resistance (Figure 2). This can generate enough excess heat to severely damage the gel and the apparatus.

General Recommendations for Protocol DNA Electrophoresis

DNA Electrophoresis • Use the same DNA loading dye (supplied with the DNA ladder/marker) for both the sample DNA and the ladder/marker DNA. • If possible, always load equal volumes of the sample DNA and the ladder/marker DNA. The sample can be diluted with 1X DNA loading dye. • Avoid high salt concentrations in the DNA samples as

Power/Running Conditions for Protein Electrophoresis

Power supplies that are used for electrophoresis hold one parameter constant (either voltage, current, or power). The PowerPac™ HC and PowerPac™ Universal power supplies also have an automatic crossover capability that allows the power supply to switch over to a variable parameter if a set output limit is reached. This helps prevent damage to the electrophoresis cell.
