A new, simple, and inexpensive method for the rapid isolation of DNA from whole blood is described. Cell nuclei are prepared by lysis of cytoplasmic membranes and DNA within the nuclear pellet is dispersed with guanidine isothiocyanate and precipitated with isopropanol. DNA prepared in this way restricts completely and results in low backgrounds of nonspecific hybridization after Southern analysis. The yields of DNA are similar to those obtained by more tedious traditional procedures. Numerous genomic DNA samples can be prepared from whole blood in 2 h, thus facilitating gene linkage or other molecular studies in which large numbers of individuals are required.

D004247 DNA A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).

D006146 Guanidines A family of iminourea derivatives. The parent compound has been isolated from mushrooms, corn germ, rice hulls, mussels, earthworms, and turnip juice. Derivatives may have antiviral and antifungal properties.
