Method to simultaneously construct 12 differently sized Illumina Nextera long mate pair libraries

The SageELF is an electrophoresis system that separates DNA or protein samples by size, and then fractionates the whole sample, or section of sample, into 12 fractions. The system is equipped with pulsed-field electrophoresis for resolving large DNA.

Fractionation ranges are estimated and adjusted in software, and fractions are collected in buffer. One sample is fractionated on a single precast agarose cassette, and one or two cassettes may be processed at one time.

Scientists from The Genome Analysis Centre report a protocol using the SageELF to improve library preparation for long mate-pair sequencing. Using a Nextera kit, they show that generating 12 fractions with SageELF saves money and time while requiring less DNA input compared to other gel-based sizing options.
