<h2>What is agarose for gel electrophoresis?</h2>
&nbsp;
Agarose is a linear polysaccharide derived from agar that, when dissolved in hot buffer and allowed to cool, forms a porous gel matrix whose pore size is determined by the agarose concentration. DNA and RNA molecules migrate through this matrix under an electric field at a rate inversely related to their size, allowing fragments of different lengths to be separated and visualized as distinct bands.

<h2>How to choose agarose type and concentration</h2>
&nbsp;
Use standard agarose at 0.7&ndash;1% for routine PCR and restriction digest checks on larger fragments
A 0.7&ndash;1% standard agarose gel is commonly used for routine PCR product verification and restriction digest analysis when fragments are generally in the 1&ndash;10 kb size range.
Use 1.5&ndash;2% standard agarose for resolving smaller fragments in the 200 bp&ndash;2 kb range
Higher agarose concentrations from 1.5% to 2% are appropriate for resolving smaller PCR products, SNP genotyping amplicons, or restriction digests where size differences below 500 bp need to be clearly distinguished.
Use high-resolution agarose at 2&ndash;4% for very small fragments or close sizing
High-resolution agarose formulations can differentiate closely sized DNA fragments in the 50&ndash;500 bp range more effectively than standard agarose, making them useful for applications such as microsatellite or STR analysis.
Choose low-melting-point agarose when you need to recover DNA from gel slices
Low-melting-point (LMP) agarose can be melted at approximately 65&deg;C after electrophoresis, allowing DNA-containing gel slices to be processed more easily for downstream enzymatic reactions or purification workflows.
Confirm agarose purity (EEO grade) for sensitive applications
Electro-endosmosis (EEO) reflects agarose purity. Low-EEO agarose supports more consistent DNA migration and helps minimize contaminants that may interfere with downstream PCR amplification, restriction digestion, or other enzymatic applications.
&nbsp;
<h2>Specifications context</h2>
&nbsp;
Standard agarose gels are typically prepared by dissolving agarose powder in TAE or TBE buffer through heating, followed by cooling to approximately 55&deg;C before pouring into casting trays. Higher-concentration gels solidify more rapidly and generally benefit from prompt casting.
As of 2026, low-EEO agarose grades remain the preferred choice for sensitive applications such as Southern blotting, gel extraction followed by PCR, and restriction enzyme digestion workflows where contaminants can inhibit downstream reactions.
