Nanobind CBB Big DNA Kit, Circulomic, USA

Product Details

Want Long Reads and High Sequencing Yields?

The Nanobind CBB Big DNA Kit is designed for rapid extraction of really big DNA from cultured cells, cultured bacteria (gram negative and gram positive), and whole blood (nucleated and non-nucleated).

Our Nanobind magnetic disks use nanostructured silica to protect DNA from shearing and facilitate washing to generate the largest and cleanest DNA for long-read sequencing and optical mapping.

This kit has been used to generate the longest sequencing data ever and can generate reads in excess of 4 Mb in length. Read length N50 of 30 – 50 kb can be expected in standard sequencing applications but N50 in excess of 150 kb can be achieved using ultra long sequencing protocols.

Combine with our Short Read Eliminator Kits to further enhance reads lengths.

Nanobind HMW DNA works well on platforms including: 1) PacBio RSII/Sequel, 2) Oxford Nanopore MinION/GridION/PromethION, 3) Bionano Genomics Irys/Saphyr, 4) 10X Genomics Chromium and 5) any other application high quality DNA is needed.

Includes protocols for HMW DNA (50 kb – 300+ kb) and UHMW DNA (50 kb – 1 Mb+) extraction.

Typical yields are 5 ug – 100+ ug per extraction depending on input.

This kit has not been validated for complex sample types.

A high-throughput version of this kit is available for automated extractions on Thermo Fisher KingFisher instruments. Contact us for details.
