HPHMW-D96 HighPrep HMW DNA Kit (96 preps)
HPHMW-D96x4 HighPrep HMW DNA Kit (384 preps)

HMW DNA isolation is suitable for molecular applications such as::

  • Long read sequencing
  • Next generation sequencing
  • Microarray
  • PCR amplification and genotyping
  • Cloning
  • Restriction enzyme digestion


  • Isolation of high-quality, high molecular weight DNA 50-300+ kb
  • HMW DNA is suitable for all third-generation sequencing platforms including Nanopore and PacBio SMRT sequencing
  • Achieve high yields of DNA from a wide range of sample matrices
  • Efficient scale-up and flexibility
  • Amenable to automation and has easy to use protocols (Kingfisher™ scripts are ready)
  • Comes with RNase to minimize the co-purification of RNA

The HighPrep High Molecular Weight DNA Kit is specifi cally designed for isolation of high molecular weight DNA (HMW DNA) in the size range of 50–300+ kb. The kit extracts HMW DNA from biological samples such as whole blood, bone marrow, saliva, buccal cells, cultured cells, tissues, and bacteria. The HighPrep High Molecular Weight DNA Kit utilizes magnetic bead-based technology in combination with chaotropic agents to gently isolate HMW DNA and remove inhibitors. The HMW DNA purifi ed with this kit is particularly suitable for analysis on long read sequencing genomic platforms including PacBio RSII/Sequel/Sequel II and Oxford Nanopore. DNA purifi ed using the HighPrep High Molecular Weight DNA Kit is of good quality and purity. The kit includes RNase A for the removal of RNA. The exact size of extracted DNA varies depending on sample matrix, the quality of the starting material, and processing conditions.

This is a short overview of the protocol. For a detailed protocol, please refer to PRODUCT DOCUMENTS.
  1. Pre-Processing (optional depending on the sample type): Homogenization of solid tissues, centrifugation or pelleting of cells from collection or growth medium.
  2. Lysis: Cell lysis, releasing DNA and RNA into the solution. Cell lysis is carried out by HAS Buff er, HTS Buff er and Pro K. RNase A degrades RNA in the sample
  3. DNA Binding: MAG-HM1 Particles in the presence of 100% Ethanol and a chaotropic salt bind the DNA in the solution.
  4. Bead Wash: Wash of MAG-HM1 Particles with HMW1 Wash Buffer and HMW2 Wash Buffer
  5. DNA Elution: Addition of a low molarity Buffer of a basic pH releases DNA from the beads into the Elution Buffer

Starting Material (Diverse Sample Types)

200 μL of blood, bone marrow, and saliva, up to 10 mg of tissue, up to 1 x 10^9 Cultured cells, bacterial pellet with OD600=1 or less, 200 μL buccal swab cells in medium

Process Method

Supports manual and automated processing


Adaptable to most nucleic acid purification instruments, but a ready-made script for Kingfi sher™ Flex is available upon request.

Purification Method

Magnetic bead-based technology

Elution Volume

30-100 μL

Size Range

50-300+ kb


A260/A280 and A260/A230 of >1.7


Depends on the quality and amount of sample. 10 mg of tissue yields 10 μg of DNA or higher. 200 μL of human whole blood yields 3-7 μg of DNA.
