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 else can I help you with?
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.
Why do we use lambda DNA used as a marker in DNA extraction?
Lambda DNA is used as a marker in DNA extraction because it serves as a reliable standard for size comparison during gel electrophoresis. Its known fragment sizes allow researchers to estimate the size of the extracted DNA and verify its integrity. Additionally, using a consistent marker like lambda DNA helps ensure reproducibility and accuracy in experimental results. This is particularly useful in applications such as cloning, sequencing, and various molecular biology techniques.
What are reversible lanes used for?
Reversible lanes are traffic lanes that can change direction based on demand, typically used to manage traffic flow during peak hours. They allow for increased capacity in one direction when needed, such as during morning or evening commutes. By adjusting lane usage, reversible lanes help alleviate congestion and improve overall traffic efficiency. Proper signage and signals are essential for ensuring driver safety and awareness when lanes are reversed.
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 the charge of dye during electrophoresis?
The charge of dyes used in electrophoresis is usually negative, allowing them to move towards the positive electrode when an electric field is applied. This movement helps visualize the migration of DNA, RNA, or protein samples in the gel.
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.
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.
What are marker lights used for?
To assist drivers in maintaining road safety, marker lights are installed in road lanes and partitions, making them easily visible. Marker lights can either be LED-powered or merely reflective.
Reversible lanes are used during?
rush hour
When are reversible lanes used?
Normally, during rush hour.
What is the function of comb in electrophoresis?
The comb is used to create wells in the gel where samples can be loaded for electrophoresis. It helps to organize the samples and ensure that they are separated properly during the process.
How can one effectively interpret electrophoresis results?
To effectively interpret electrophoresis results, one must analyze the pattern of bands on the gel, noting the size and intensity of each band. Comparing the results to a standard marker can help determine the size of the DNA fragments. Additionally, understanding the principles of electrophoresis and the specific experimental conditions used can aid in interpreting the results accurately.
Why do we use lambda DNA used as a marker in DNA extraction?
Lambda DNA is used as a marker in DNA extraction because it serves as a reliable standard for size comparison during gel electrophoresis. Its known fragment sizes allow researchers to estimate the size of the extracted DNA and verify its integrity. Additionally, using a consistent marker like lambda DNA helps ensure reproducibility and accuracy in experimental results. This is particularly useful in applications such as cloning, sequencing, and various molecular biology techniques.
What gel is typically used in electrophoresis experiments?
The gel typically used in electrophoresis experiments is agarose gel.

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.
