agarose versus polyacrylamide: not all gels are created equal

Agarose versus Polyacrylamide: Not All Gels Are Created Equal

Like athletes running on turf versus sand, the gel you run your DNA through can highly affect your results. The two main types of gels that people use for DNA electrophoresis are agarose and polyacrylamide (PA) gels, but figuring out the differences can be confusing. Basically, you choose a gel based on two main factors: how high you need the resolution to be and what is in your samples. To

agarose gel electrophoresis for the separation of dna fragments

Agarose Gel Electrophoresis for the Separation of DNA Fragments

DNA fragments smaller than 100 bp are more effectively separated using polyacrylamide gel electrophoresis. Unlike agarose gels, the polyacrylamide gel matrix is formed through a free radical driven chemical reaction. These thinner gels are of higher concentration, are run vertically and have better resolution.

Like agarose, polyacrylamide too is used in molecular biology as an important resolution tool in a similar process called ‘Polyacrylamide gel electrophoresis’ (PAGE). In addition to all of this, Polyacrylamide is also used in ore processing and manufacturing of flocculating agent to remove any suspended organic material; hence, improving

Running agarose and polyacrylamide gels

Agarose gels can be run at a large range of voltages—from 0.25–7 V/cm. High voltages save time but can result in overheating of the gel, even leading to melting of low percentage agarose gels. High voltages can also cause band smearing, particularly of fragments >10 kb.

However, highly cross-linked gels (> 10%C) (%C: grams of cross-linker per 100 g of total monomers) can, at very high cross-link levels (> 30%C), have porosities comparable with, or even greater than, agarose matrices. High %C polyacrylamide matrices, however, are brittle, opaque, and tend to collapse and exude water above 30%C. Thus, their use

Polyacrylamide gel is good for such separation. However due to such large DNA fragments you are dealing with, you may need a lower % polyacrylamide gel, maybe 2-3%. I use 6% PAGE for 100 - 300bp. If you want to use agarose, you may need a LONGER gel length with lower % in order to resolve the fragments. Good luck!

What Percentage Agarose Is Required For Electrophoresis?

Use a high percentage agarose gel. Between 2.00% and 3.00% should help. Higher concentration gels have a better resolving power. Create a larger agarose gel. If the gel is longer, this means the samples can be run for longer without them running off into the abyss. Longer runs mean better separation. Run the electrophoresis slowly for longer.

In PAGE, rather than agarose, we use a chemical called polyacrylamide. Varying the percentage of polyacrylamide in the gel lets us change the size of the pores in the gel, which means that we can separate different sizes of protein in different percentage gels. Typical gel percentages are shown in the table below.

Agarose gel has lower resolving power than polyacrylamide gel for DNA but has a greater range of separation, and is therefore used for DNA fragments of usually 50–20,000 bp in size. The limit of resolution for standard agarose gel electrophoresis is around 750 kb, but resolution of over 6 Mb is possible with pulsed field gel electrophoresis
