Genomic DNA

Genomic DNA, or gDNA, is the chromosomal DNA of an organism, representing the bulk of its genetic material. It is distinct from bacterial plasmid DNA, complementary DNA, or mitochondrial DNA. Genome sizes vary by organism, ranging from a few kilobases in viruses, a few megabases in bacteria, and tens to hundreds of gigabases in higher eukaryotes. Humans have an estimated genome size of 3.2 billion base pairs (or 3.2 Gb). In research, genomic DNA are useful tools in applications such as PCR, library construction, Southern blotting, hybridizations, SNP analysis, and molecular diagnostic assays. Here, we provide a number of commercial sources of gDNA, purified from a variety of relevant species, including microbial strains, and tissue types. There are also a number of human gDNA taken from patients of specific diseases, notably cancer. Ready-to-use salmon sperm and calf thymus DNA are also available in the preparation of hybridization solutions.
