Definition

1. Noun:
   • A laboratory technique for separating charged molecules: "paper electrophoresis" is a specific analytical method where an electric field is applied to a sample on a strip of filter paper, causing molecules (like proteins or nucleic acids) to migrate and separate based on their charge and size.

Usage Examples

• Noun:
  • The researcher used paper electrophoresis to analyze the serum proteins.
  • Paper electrophoresis was a common technique in mid-20th century biochemistry.

Advanced Usage

• "to perform paper electrophoresis": to carry out this specific laboratory procedure.
  • The protocol describes how to perform paper electrophoresis on these dyes.

Variants and Related Words

• Electrophoresis (n): the broader category of separation techniques using an electric field.
  • Gel electrophoresis has largely replaced paper electrophoresis for many applications.
• Filter paper (n): the porous paper medium used in this technique.
• Zone electrophoresis (n): a general term for electrophoresis performed on a stabilizing medium, such as paper or gel.

Synonyms

• Filter paper electrophoresis: A more descriptive synonym.
• Paper-strip electrophoresis: Another term for the same technique.

Notes on Meaning

This term refers specifically to the historical and methodological use of filter paper as the supporting medium. It is considered a simpler, older form of electrophoresis compared to modern gel-based methods. The core meaning is inseparable from the tool (paper) and the process (electrophoresis).

Noun

1. electrophoresis carried out on filter paper
