Study Notes

Electrophoresis

Electrophoresis is a laboratory technique used to separate and analyze mixtures of charged particles, such as proteins or nucleic acids, based on their size and charge.

Gel Electrophoresis

Gel electrophoresis is a type of electrophoresis that uses a gel matrix to separate charged particles.
The purpose of gel electrophoresis is to separate, identify, and purify mixtures of charged particles, such as DNA, RNA, and proteins.

Applications of Gel Electrophoresis

One of the main applications of gel electrophoresis in biomedical sciences is to analyze DNA fragments in forensic science, genetic engineering, and gene expression studies.

Principle of Gel Electrophoresis

In gel electrophoresis, charged particles move at different rates due to their size and charge, with smaller particles moving faster than larger ones.
The general principle of gel electrophoresis is that charged particles migrate through a gel matrix in an electric field, separating according to their size and charge.
