All Bio-Rad Certified™ Agarose products are guaranteed to be free of inhibitors, DNases, and RNases.

Certified™ Molecular Biology Agarose, a very high molecular weight linear polymer with a low sulfate content produces a gel with high gel strength and a high exclusion limit. Gels are easy to handle even at low agarose percentages. Analytical separation is ≥1,000 bp. Certified™ PCR Agarose separates DNA fragments ≤1,000 bp. This high-strength agarose is easy to handle, remaining flexible even at high gel percentages. This agarose gels at 40°C. Certified™ Low Range Ultra Agarose resolves small PCR fragments and primers at lower concentrations than standard agaroses. A 3% gel resolves a 10 bp ladder, and a 4% gel approaches the resolution of an 8% polyacrylamide gel. Analytical separation is 20–800 bp.

Certified™ Megabase Agarose is a very high gel strength, high electrophoretic mobility, and high exclusion limit agarose for CHEF and FIGE applications. Easy to handle at concentrations as low as 0.3%. The separation range is 1 kb–5 Mb. Certified™ Low-Melt Agarose, for DNA fragments ≥1,000 bp, is recommended for preparative electrophoresis and in-gel applications such as digestion and ligation, as well as embedding chromosomes and megabase DNA for PFGE. Certified™ PCR Low-Melt Agarose has a high sieving capacity and yields excellent resolution of fragments ≤1,000 bp in a low-melt or preparative format. This agarose is ideal for digestion by agarase and all in-gel applications. Pulsed Field Certified™ Agarose provides excellent separation and resolution of large DNA fragments in PFGE, with an optimal separation range of 1 kb–2 Mb.
