Abstract
DNA-containing hair root cells are liberated from hair samples by soaking the hair root ends of the hair shafts in an aqueous solution consisting essentially of dithiothreitol, a surfactant such as sodium dodecylsulfate, a chelate such as ethylenediamine tetraacetic acid, an inorganic salt (NaCl), tris(hydroxymethyl) aminomethane and sufficient hydrochloric acid to make the pH of the solution approximately 8.
