Are you a student or researcher in the field of biochemistry or molecular biology? If yes, then you must have heard about gel electrophoresis semi log graph. This technique is widely used for separating and analyzing DNA, RNA, and proteins based on their size and charge. In this blog post, we will discuss the basics of gel electrophoresis semi log graph and its applications in modern research.

What is Gel Electrophoresis Semi Log Graph?

Gel electrophoresis semi log graph is a technique used to separate and analyze biological macromolecules such as DNA, RNA, and proteins. The technique involves applying an electric field to a gel matrix that contains the biological sample. The samples are loaded onto the gel matrix and are then subjected to an electric field. This causes the samples to migrate through the gel matrix at a rate that is determined by their size and charge.

The gel matrix used in gel electrophoresis semi log graph is usually made of polyacrylamide or agarose. Polyacrylamide gels are commonly used for separating proteins, while agarose gels are commonly used for separating DNA and RNA. The gel matrix is prepared by mixing the gel-forming material with a buffer solution and a catalyst. The mixture is then poured into a mold and allowed to polymerize.

The Principle of Gel Electrophoresis Semi Log Graph

The principle of gel electrophoresis semi log graph is based on the fact that biological macromolecules such as DNA, RNA, and proteins have a negative charge due to the presence of phosphate groups and carboxyl groups. When an electric field is applied to a gel matrix, the negatively charged macromolecules migrate towards the positively charged electrode. The rate of migration is determined by the size and charge of the macromolecule.

The gel matrix used in gel electrophoresis semi log graph is usually divided into two parts: the stacking gel and the separating gel. The stacking gel is a lower concentration gel that is used to concentrate the sample into a narrow band. The separating gel is a higher concentration gel that is used to separate the macromolecules based on their size.
