No, the agarose gel is just a polysaccharide.
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.
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.
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..).
Agarose 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.
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.

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.

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.
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.

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.
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.
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.

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.
