Use CHEF* DNA size standards for size estimation of larger DNA fragments separated by pulsed field electrophoresis.

  • Size range: 48.5–1,000 kb in 48.5 kb increments (λcl857Sam7 concatemers)
  • Recommended gels: 0.8–1.0% Pulsed Field Certified™ Agarose or molecular biology grade agarose

Note: Cut a plug from a block into a size that will fit a well of your gel (5–8 plugs per block). The height of the plug should not extend above the well. After placing the plug into a well, seal the well with melted 1.0% low-melt agarose, and allow it to solidify. Store blocks at 4°C.
