Agarose Gels

  1. Contrary to what you might expect, very large fragments of DNA readily move in agarose gels when an electrical field is applied. (Web site)

Electrical Charges

  1. The electrical charges (nerves impulses) created by the billions of neurons in the brain combine to generate an electrical field. (Web site)


  1. Proteins carry a positive or a negative electrical charge, and they move in fluid when placed in an electrical field.
  2. In a clinical protein electrophoresis test, proteins are separated on the basis of how fast they move on a medium in an electrical field. (Web site)

  2. Electrophoresis is a technique that separates large molecules by size using an applied electrical field and a sieving matrix. (Web site)

Isoelectric Point

  1. Thus, the isoelectric point is the value of pH at which the colloidal particle remains stationary in an electrical field. (Web site)

Electrical Field

  1. Serum protein electrophoresis uses an electrical field to separate the proteins in the blood serum into groups of similar size, shape, and charge.
  2. Gel electrophoresis is a procedure that separates molecules on the basis of their rate of movement through a gel under the influence of an electrical field.
  3. The electrical field causes the electrons to move from the semiconductor toward the negative surface, where they become available to the electrical circuit.
