Purified Genomic DNA Sample Collection
Collection of purified high-molecular-weight genomic DNA from all target species
Purpose
Collection of purified high-molecular-weight genomic DNA from all target species
Context
Child of L2-GEN-DNA
Principles
- ▸Phenol-chloroform extraction or column-based kits produce high-purity DNA
- ▸High-molecular-weight DNA (>50 kbp) essential for complete genome representation
- ▸DNA quantified by fluorometry (Qubit) and quality assessed by electrophoresis
- ▸Multiple aliquots per species stored in separate locations for redundancy
Typical implementations
- ▸Qiagen DNeasy and Gentra Puregene DNA extraction kits
- ▸Phase Lock Gel tubes for phenol-chloroform extraction
- ▸Global Genome Initiative (Smithsonian) DNA extraction protocols
Lunar considerations
- ▸Extracted DNA degrades over time even at -80C to -196C (depurination, hydrolysis)
- ▸Silica encapsulation dramatically extends DNA stability
- ▸DNA quality at extraction determines maximum usable lifetime in storage
