In electrophoresis, the primary type of support media used is a gel, commonly composed of agarose or polyacrylamide. These gels provide a matrix through which charged molecules, such as DNA, RNA, or proteins, can migrate when an electric field is applied. The choice of gel type and concentration affects the resolution and separation of the molecules based on their size and charge. Additionally, buffer solutions are used to maintain the pH and ionic strength during the electrophoresis process.

What is zone electrophorosis?
Zone electrophoresis is a type of electrophoresis where molecules are separated based on differences in their electrophoretic mobility in a homogenous support medium, such as a gel or a capillary. It is commonly used to separate proteins, nucleic acids, and other charged molecules based on size and charge. Zone electrophoresis is a powerful technique for analyzing complex mixtures of biomolecules.
What was used before gel electrophoresis?
Before gel electrophoresis, techniques like paper electrophoresis and agarose slab gel electrophoresis were used for separating and analyzing DNA or proteins. These methods were less efficient and had lower resolution compared to gel electrophoresis.
What is a culture media used to support growth of microorganisms?
Agar
What kind of macromolecules can you look at with gel electrophoresis do you need to use different techniques for the different kinds of macromolecules?
You can look at nucleic acids (DNA and RNA) and proteins using gel electrophoresis. However, different techniques are needed for each type of macromolecule. For nucleic acids, agarose gel electrophoresis is commonly used, while for proteins, polyacrylamide gel electrophoresis is typically employed.

Some viva voce questions for electrophoresis?
1. WHAT IS ELECTROPHORESIS AND WHAT ARE THE IMPORTANTAPPLICATIONS OF ELECTROPHORESIS?Ans. Movement of charged particle in the electric field either towards cathode or anode whensubjected to an electric current is called electrophoresis.The following factors influence the movement of particles during the electrophoresis.(a) Electric current.(b) Net charge of the particle.(c) Size and shape of the particle.(d) Type of supporting media.(e) Buffer solution.Important Applications of ElectrophoresisThe technique of electrophoresis is used to separate and identify the(i) Serum proteins(ii) Serum lipoproteins(iii) Blood hemoglobins2. WHAT ARE THE DIFFERENT TYPES OF ELECTROPHORESIS?Ans. (a) Moving boundary electrophoresis: This technique was first introduced by TISELIUS in 1937(b) Zone electrophoresis: In this type of electrophoresis different types of supporting mediaare used. These are;(a) Paper electrophoresis(i) Whatman filter paper(ii) Cellulose acetate(b) Gel electrophoresis(i) Agarose.(ii) Polyacrylamide gel (used for the separation of isoenzymes).(iii) SDS-PAGE.(iv) Iso-electric focussing (proteins seperated in a medium possessing a stable pH gradient).(v) Immuno electrophoresis (for the separation of immunoglobulins).
What gel is typically used in electrophoresis experiments?
The gel typically used in electrophoresis experiments is agarose gel.
What is a simple media?
In this media non-complicated ingredients are used to support the growth of microbes
What criteria should be used to select network media?
The criteria used to select a network media is the type of media.
What is one example of a type of media that might be used in a speech?
One example of a type of media that might be used in a speech is a slideshow presentation with visual aids like images, graphs, or videos to support and enhance the speaker's message.
What is the definition for paper electrophoresis?
Paper electrophoresis is a technique used for separating charged molecules, such as proteins or nucleic acids, based on their migration in an electric field through a paper support. The movement of molecules is influenced by their charge and size, allowing for separation and analysis. Paper electrophoresis is a cost-effective and simple method commonly used in biochemistry and molecular biology research.
What was used before gel electrophoresis?
Before gel electrophoresis, techniques like paper electrophoresis and agarose slab gel electrophoresis were used for separating and analyzing DNA or proteins. These methods were less efficient and had lower resolution compared to gel electrophoresis.
Difference between vertical and horizontal gel electrophoresis?
Horizantal gel electrophoresis is generally used for RNA/DNA based studies, while vertical gel electrophoresis is used for protein based studies.
