An example of protein electrophoresis is SDS-PAGE ( sodium do-decyl sulpahate-polyacrrlamide gel electrophoresis).
Another example includess " isoelectric focusing".
In isoelectric focusing the protein is separated on the basis of its net charge.
The main principle lies on the basis of finding isoelectric point i.e. at which the net charge on the protein is zero.
The protein is loaded in the gel and then it separates itself on the basis of the charge.
NEgatively charged on the negative side and positively gharged on the positive side and the neutral ones in the centre.

What lab department does protein electrophoresis?
The Clinical Chemistry Section of a Hospital Pathology Laboratory will prpbably undertake protein electrophoresis on the blood samples from patients.
What happens to protein charge if pH value becomes lower than pi in 2 dimensional gel electrophoresis?
If the pH value becomes lower than the protein's isoelectric point (pI) in 2D gel electrophoresis, the protein will acquire a net positive charge due to the excess of protons. This will cause the protein to move towards the cathode during electrophoresis.
What is cause of faster protein migration in electrophoresis?
The main factors that can cause faster protein migration in electrophoresis are higher voltage, smaller pore size of the gel matrix, and lower molecular weight of the protein. These factors can increase the speed at which proteins move through the gel during electrophoresis.
What is protein marker and what is its use in electrophoresis?
A protein marker is a mixture of proteins of known sizes that is run alongside unknown samples in electrophoresis. It is used as a reference to help estimate the size of the unknown proteins based on their migration pattern in the gel. This allows researchers to determine the size of proteins in their samples and compare them to standards.
What is the main difference between protein electrophoresis and nucleic acid electrophoresis?
There are many similarities and differences between protein and DNA electrophoresis.Similarities:PAGE protein and DNA electrophoresis both cause separation by size, creating bands that are viewed by the scientist or a machine. The smallest segments more the fastest due to less friction with the surface of their medium or equipment.The movement of charges through the medium is what causes the DNA or proteins to move. Electrons move from the negative to positive end of the gel or capillary tube.Differences:In PAGE protein electrophoresis, a polyacrylamide gel is used to prevent convection from altering the movement of the proteins. If the proteins are charged, and there is a worry that the charge will affect the mobility of the protein segments, 1% SDS can be added to get rid of the mass/charge issue. This way, only the mass of the segment determines how far it moves. In DNA capillary electrophoresis, the size of the capillary is so small that it does not have room for convection to occur (it is only 20-50 microns wide). Thus, there is no medium in the capillary but DNA itself.In protein electrophoresis, the proteins are often dyed so their movement can be viewed with the naked eye, or a machine. With DNA capillary electrophoresis, DNA strands are made through DNA replication with dNTPs that are fluorescently labeled for the different nucleotides. Each base is labeled a different color. A fine laser lights up the DNA strand in the capillary tube and reads what color fluoresces. This is how the nucleotide is identified.Protein PAGE electrophoresis is used to determine the purity of a protein sample. It can also be used to see how large the chains are that make up a multi-chain protein if a denaturing agent is added. DNA electrophoresis is used to get the order of nucleotides in a DNA sequence. It is done by chopping the DNA sequence into many smaller bits and sequencing them, then putting them back together by lining them up according to sequence overlaps. This is called the "shotgun" method. Protein electrophoresis can figure out the order of about 15-20 amino acids by a similar method, but DNA electrophoresis can get up to 1000 nucleotides (~300 amino acids). DNA electrophoresis is limited by the low probability that the DNA sequence would be cut into a segment greater than 1000 nucleotides.

What color test tube for protein electrophoresis?
For protein electrophoresis, a clear or colorless test tube is typically used. This allows for easy visualization of the protein bands after electrophoresis is complete. Any other colored test tube could interfere with accurate observation and analysis of the results.
What happens to protein charge if pH value becomes lower than pi in 2 dimensional gel electrophoresis?
If the pH value becomes lower than the protein's isoelectric point (pI) in 2D gel electrophoresis, the protein will acquire a net positive charge due to the excess of protons. This will cause the protein to move towards the cathode during 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.
What is cause of faster protein migration in electrophoresis?
The main factors that can cause faster protein migration in electrophoresis are higher voltage, smaller pore size of the gel matrix, and lower molecular weight of the protein. These factors can increase the speed at which proteins move through the gel during electrophoresis.

What is a gel electrophoresis is not used for?
Gel electrophoresis is not typically used for determining the function of proteins or for studying protein-protein interactions. It is primarily used to separate and analyze DNA, RNA, or proteins based on their size and charge.
What color tube do you use to draw Protein electrophoresis?
Typically, a lavender or purple-top tube is used to collect a blood sample for protein electrophoresis testing. These tubes contain EDTA as an anticoagulant to prevent clotting and preserve the blood sample for analysis.
