What else can I help you with?
Why the pH of stacking gel and resolving gel are different?
Stacking gel has a different pH from resolving gel because stacking gel is made out of Tris?HCI buffer which has a pH of 6.8. This makes sure that it is about 2 units different from the pH of resolving gel.
Why stacking gel used in electrophoresis?
Stacking gel is used in electrophoresis to concentrate and focus the sample of DNA, RNA, or protein at the top of the separating gel before the separation step begins. This allows for better resolution and separation of the molecules as they move through the gel, resulting in clearer and more accurate results.
How do you get agarose gel to solidify when it doesn't solidify after 10 min in the refrigerator?
Try increasing the concentration of agarose in your gel mixture or extending the cooling time in the refrigerator. You can also check if the agarose powder is expired or if there was an error in the preparation process. If the issue persists, consider using a different brand or batch of agarose.
Function of resolving gel in SDS PAGE?
Generally, SDS-PAGE is carried out with a discontinuous buffer system. It consists of a stacking gel(approximately 0.8-1cm) poured over a resolving gel (approximately 5-6cm long). The protein samples and stacking gel are prepared using Tris-Cl (pH 6.8), whereas the resolving gel is made in Tris-Cl (pH 8.8). However, for running the gel, the buffer reservoirs are filled with Tris-glycine buffer (pH 8.3). This provides differences in the pH and ionic strength between the electrophoresis buffer and the buffers used to cast the gel. As a result, the proper separation of the proteins is achieved.In order to prepare the gel, first, resolving gel (usually 10-12%) is poured between the glass plates. Generally, spacers of 0.75-1mm are used between the glass plates. Immediately, a layer of deionized water is added. This gives a uniform straight surface to the resolving gel and also helps in removing any un-polymerized residual form of the gel.After polymerization, the water layer is removed by turning the glass plate assembly upside down for a few seconds. Then stacking gel of larger pore size (usually 4-5%) is poured. A comb is inserted from the top of the glass plate assembly to make the wells. After the completion of polymerization, comb is removed and wells are rinsed with deionized water to remove any un-polymerized gel portion. The main function of stacking gel is to concentrate the protein samples into a sharp band before their entry into the resolving gel.

What are the differences between stacking gel and resolving gel in gel electrophoresis?
In gel electrophoresis, the stacking gel is used to concentrate and separate the samples before they enter the resolving gel. The resolving gel then separates the samples based on their size and charge. The stacking gel has a lower concentration of acrylamide, allowing for faster movement of the samples, while the resolving gel has a higher concentration for better separation.

What is the function of the gel?
Separating gel allows the separation of protein molecules according to their molecular weight by sieving effect of pores in the gel(percentage). The pH of separating or resolving gel is 8.8, whereas stacking gel (upper gel that squeezes protein as a thin layer) made of pH6.8.
What is the function and usage of stacking gel in sds-page?
The stacking gel is a large pore PAG (4%T). This gel is prepared with Tris/HCl buffer pH 6.8 of about 2 pH units lower than that of electrophoresis buffer (Tris/Glycine). These conditions provide an environment for Kohlrausch reactions determining molar conductivity, as a result, SDS-coated proteins are concentrated to several fold and a thin starting zone of the order of 19 μm is achieved in a few minutes. This gel is cast over the resolving gel. The height of the stacking gel region is always maintained more than double the height and the volume of the sample to be applied.this is based on [isotachophoresis] that is glycine from electrophoresis buffer have lower electrophoretic mobility than protein-sds complex which is less mobile than cl- ions.giycine-

What are the steps involved in running RNA on an agarose gel for analysis?
To run RNA on an agarose gel for analysis, the steps typically involve preparing the gel by mixing agarose with a buffer, heating the mixture to melt the agarose, pouring the liquid gel into a mold, adding a comb to create wells for loading samples, allowing the gel to solidify, preparing the RNA samples by mixing them with a loading dye, loading the samples into the wells, running an electric current through the gel to separate the RNA molecules based on size, staining the gel to visualize the RNA bands, and analyzing the results.
