PROCESS FOR PREPARING BIOLOGICAL SAMPLES

摘要

Methods and compositions for preparation of a sample, including a sample to be analyzed for the presence of one or more pathogens. Transport of a non-diluted sample from an individual suspected of having the pathogen and transfer of the sample directly into a nucleic acid extraction buffer occurs in a single step. The process is an improvement over known methods because it provides accurate, rapid analysis that utilizes fewer steps and/or reagents from methods used in the art. In specific embodiments, it has one or more of the following characteristics: 1) it is a one-step process; 2) it eliminates dilution of the sample; 3) smaller sample sizes are employed; 4) fewer reagents are utilized; 5) transport media is not required; 6) less than 1 colony forming unit is required for detection; 7) fast; and 8) economic.
