What is a maker lane in electrophoresis?
A maker lane in electrophoresis is a designated lane in a gel where a molecular weight marker or ladder is run alongside the samples. This marker contains a mixture of DNA, RNA, or protein fragments of known sizes, allowing for the estimation of the sizes of the sample bands based on their position relative to the marker. It serves as a reference to help researchers determine the molecular weight of the unknown samples being analyzed.
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.
Why the marker lanes are used during electrophoresis?
The marker lanes are important in electrophoresis because in these lanes peptides or proteins with known molecular sizes and weights (standards) run beside, on the same gel, with the sample and the Rfs (relative mobilities) of the developed bands of the unknown proteins can be compared with those of the standards.
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 the purpose of the marker in gel electrophoresis?
The purpose of the marker in gel electrophoresis is to help determine the size of DNA fragments by providing known reference points for comparison.

What has the author A J Houtsmuller written?
A. J. Houtsmuller has written: 'Agarose-gel-electrophoresis of lipoproteins' -- subject(s): Blood protein electrophoresis, Electrophoresis, Gel electrophoresis, Lipoproteins
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.
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.

One lane of an electrophoresis gel shows a 100bp ladder. What is the purpose of this ladder?
It is used as a marker for molecular weight.

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 a marker protien?
A protein marker is just that - a marker for specific proteins. This usually deals with running an experiment (assay) to determine the presence, absence, and with some markers, abundance of a specific protein
