A Simple and Quick Way to Consistent NGS Results

Magnetic bead-based MagSi-NGSPREP Plus offers an efficient solution for both size selection and clean-up of the successive enzymatic reactions in library preparation for NGS applications. The simple and flexible protocol can be adjusted to your specific library preparation kit and NGS instrument. MagSi-NGSPREP Plus can be used manually but is also easy to automate for high-throughput processing. In conclusion: a simple and quick way to consistent sequencing results.

The MagSi-NGSPREP Plus kit is optimized for use on Biomek® Laboratory Automation Workstations and Hamilton® MicroLab STARline. MagSi-NGSPREP Plus allows either non-selective binding, or size-targeted binding of double-stranded DNA fragments ranging from 80 – 1000 bp with specific reagent volume to sample volume ratio’s. By increasing the volume of MagSi-NGSPREP Plus, the efficiency of binding smaller fragments increases. This enables the user to selectively keep or discard undesired fragment sizes.

MagSi-NGSPREP Plus’ flexible protocols are easy to automate for high-throughput screening.
