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.
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).
Does gel electrophoresis separate molecules based on their charge?
Yes, gel electrophoresis separates molecules based on their size and charge.
What color tube is drawn for a hgb electrophoresis?
A lavender-top (EDTA) tube is typically used for drawing blood samples for hemoglobin electrophoresis testing.
Which pieces of DNA will migrate to the bottom of the DNA gel first during electrophoresis?
During electrophoresis, smaller pieces of DNA will migrate to the bottom of the gel first.

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.
Can a gel electrophoresis be performed both horizonnally and vertically?
yes for example 2D gel electrophoresis
What are the application of paper electrophoresis?
Paper electrophoresis is used to analyze scientific experiments. One use in scientific experiments for paper electrophoresis is to determine the presence of HIV from blood samples.
Where can one learn more on gel electrophoresis?
To learn more about gel electrophoresis, one can Google it. There is also a whole Wikipedia article dedicated to gel electrophoresis, and it happens to be quite informative.
What causes the absence of bands in gel electrophoresis?
The absence of bands in gel electrophoresis can be caused by factors such as improper loading of samples, insufficient DNA concentration, or issues with the gel or electrophoresis equipment.
What do the bands in gel electrophoresis represent?
The bands in gel electrophoresis represent different sizes of DNA fragments.
What gel is typically used in electrophoresis experiments?
The gel typically used in electrophoresis experiments is agarose gel.
