Electrophoresis per se cannot be used to implicate a suspect. Rather, electrophoresis is merely one of many analytical techniques which may be applied to a specific question, being posed by a an investigator. The value of electrophoresis is nil outside the data quality objectives (DQOs) presented by the investigating team, and the QA/QC program of the analyzing laboratory. Without QA/QC, in the lab, and without appropriate DQOs, electrophoresis is no more capable of implicating a suspect than a ouija board. Laboratories cannot perform in the real world as seen on TV's CSI, and real CSIs would go to jail if they pulled some of the stunts seen on the TV series.

What are the differences between tris-glycine and bis-tris gels in terms of their composition and performance in protein electrophoresis?
Tris-glycine gels contain both tris and glycine buffers, while bis-tris gels use bis-tris buffer. Bis-tris gels offer better resolution and sharper bands in protein electrophoresis compared to tris-glycine gels.
What are the differences between bis-tris and tris-glycine gels in terms of their composition and performance in protein electrophoresis?
Bis-Tris gels and Tris-Glycine gels differ in their composition and performance in protein electrophoresis. Bis-Tris gels use bis-Tris buffer and have a more stable pH range, resulting in sharper protein bands. Tris-Glycine gels use Tris-Glycine buffer and are more commonly used for separating smaller proteins. Overall, the choice between the two gels depends on the specific needs of the experiment and the proteins being analyzed.
what is the gel in Gel Electrophoresis?
The gel in gel electrophoresis is typically made of agarose or polyacrylamide. It acts as a matrix to separate DNA, RNA, or proteins based on size and charge as an electric current passes through it. Agarose gels are commonly used for DNA analysis, while polyacrylamide gels are often used for higher resolution protein separation.
What are the differences between tris-glycine gel and bis-tris gel in terms of their composition and performance in protein electrophoresis?
Tris-glycine gels use a combination of tris and glycine buffers, while bis-tris gels use a bis-tris buffer system. Bis-tris gels offer better resolution for larger proteins due to their pH stability, while tris-glycine gels are more commonly used for smaller proteins.
What are the best gel electrophoresis kits available for purchase?
There are several reputable gel electrophoresis kits available for purchase, including those from companies like Bio-Rad, Thermo Fisher Scientific, and Agilent. These kits typically include all the necessary components for running gel electrophoresis experiments, such as agarose gels, buffers, and DNA markers. It is recommended to choose a kit based on your specific research needs and budget.
Are electrophoresis gels hazardous?
Electrophoresis gels can pose hazards due to the chemicals and dyes used in their preparation, as well as the potential for exposure to ultraviolet light during visualization of the separated DNA or proteins. It is important to handle electrophoresis gels with proper safety precautions, including wearing appropriate personal protective equipment and disposing of them properly.

Tris-glycine gels contain both tris and glycine buffers, while bis-tris gels use bis-tris buffer. Bis-tris gels offer better resolution and sharper bands in protein electrophoresis compared to tris-glycine gels.
What is Laemmli gels?
Laemmli gels are a type of polyacrylamide gel used in protein electrophoresis. They are commonly used in the separation of proteins based on their size during techniques such as SDS-PAGE. Laemmli gels are named after the scientist who developed the gel electrophoresis technique, Ulrich K. Laemmli.

When is DNA cut during electrophoresis?
Electrophoresis technique is not designed to cut DNA molecule. When DNA is analyzed by electrophoresis to determine its molecular mass, the molecular biology engineer usualy digests the DNA molecule, before the electrophoresis, with specific enzymes called "restriction enzymes" in order to obtain fragments of diverse molecular weights that can be seen as bands in electrophoresis gels.
Can sds gels be reused?
SDS gels cannot typically be reused because the separating gel portion degrades during the electrophoresis process. However, stacking gels may be reusable if they remain intact and free from contamination. It is recommended to prepare fresh gels for subsequent experiments to ensure accurate and reliable results.

What is amido black?
Amido black is a dye commonly used for staining proteins in electrophoresis gels. It binds specifically to proteins and can be visualized after staining to help identify the presence and quantity of proteins in a sample.

Why native gel electrophoresis can be used for determining the molecular weight of proteins?
No! native gels are used to run the proteins in native form, this will tell about the protein's mulimeric nature (ie.monomer or dimer or tetramer etc..).
