UltraPure Agarose is standard melting-point agarose designed for routine separation analysis of DNA and RNA fragments in the 500–23,000 bp range. UltraPure Agarose 1000 is a specialized agarose that provides higher resolution of PCR fragments and other short DNA fragments. Agarose 1000 is easier to handle because it has a stronger gel structure: gel strength >1,400 g/cm2. For low melting/gelling temperature agarose, UltraPure Low Melting Point Agarose is recommended for rapid DNA gel extraction protocols. Listed below are some reasons and tips to use LMP agarose.

Reasons to use low melting point (LMP) agarose

Low melting point (LMP) agarose is ideal for resolving DNA fragments from 10 bp to 1,000 bp. The major advantage of LMP agarose is the low melting temperature of 65°C or less. At these temperatures, it is possible to remelt the agarose of a gel without melting the double helix of DNA molecules in the agarose. Therefore, slices of LMP agarose containing DNA can be melted and the nucleic acids manipulated directly in the remelted agarose.

Tips for using LMP agarose:

  • Use 1x TAE buffer instead of 1x TBE buffer
  • Stain the gel after electrophoresis with SYBR Safe DNA gel stain. Ethidium bromide staining can result in DNA degradation.
  • Visualize DNA with UV light source ≥300 nm and minimize exposure to less than 1 minute.
  • Melt the gel slice at 65°C. Do not exceed 70°C, which may result in DNA denaturation.
