An easier, but less accurate, method uses a spot-urine protein electrophoresis.

It is produced by the liver, and is a major component of the alpha-2 band in protein electrophoresis.

Using protein electrophoresis, these two groups can be separated into five smaller groups (fractions):

They confirmed the genetic difference of the two species by the means of protein electrophoresis.

The term alpha-1 refers to the protein's behavior on protein electrophoresis.

See protein electrophoresis for more information on the different globulins.

Some years later, he was awarded the 1948 Nobel Prize for his work in protein electrophoresis.

Work with protein electrophoresis began around 1956.

Because of practical limitations, protein electrophoresis is generally not suited as a preparative method.

Immunofixation is however only sensitive to immunoglobulins and is more expensive than protein electrophoresis.
