The blood genomicPrep Mini Spin Kit is designed for the rapid and reproducible isolation of high-quality genomic DNA from whole blood, buffy coat, bone marrow, and nucleated red blood cells.

• High-quality genomic DNA with a greater proportion of higher molecular weight DNA and less shearing
• Demonstrated application to various types of whole blood including human, horse, rabbit, rat, and mouse
• Increased ease of use with reduced pipetting volume changes, one centrifugation setting, and color-coded kit components
• Verified in several downstream applications including real-time PCR, endpoint PCR, multiplex PCR, and restriction enzyme digests

Genomic DNA is found in the chromosomes and it is much longer and higher in molecular weight than plasmid DNA. Genomic DNA is the code for the genome, and this is what is needed to do genome sequencing.

For sequencing it is desirable that the genomic DNA extraction technique used allows the collection of intact genomic DNA in the longest fragments possible. A kit format can help standardize the procedures used to prepare tissue and cell genomic DNA samples for analysis.

The purification process involves minimal shearing resulting in the production of 5 to 10 μg of good quality, intact genomic DNA from a 200 μL sample. Input sample volumes can vary from 50 μL to 1 mL.

The method uses a simple genomic DNA purification protocol. This protcol that uses chaotropic agents to extract DNA from blood cells, denature protein components, and promote the selective binding of DNA to a column-based, novel silica membrane. This results in high molecular weight DNA that can be used downstream (e.g., in bone marrow genomic DNA for next generation sequencing).

The elution volume can be modified as necessary to obtain the appropriate genomic DNA concentration for most downstream molecular biological applications.
