Abstract
The present invention provides methods and apparatus for detecting and discriminating multiple analytes within a test sample which are simple, user-friendly, cost-effective and fast. In particular, it is preferred that the overall time for sample preparation, nucleic acid sequence amplification, and nucleic acid sequence differentiation be about 5 hours or less. The methods of the present invention comprise (i) rapid sample processing means for rapidly preparing sample material of various types for amplification of nucleic acid sequences using unique nucleic acid extraction buffer formulations, (ii) multianalyte non-preferential amplifying process means for simultaneously and non-preferentially amplifying multiple target nucleic acid sequences, if present within the sample, using appropriate primer oligonucleotides optimized to achieve substantially similar amplification efficiencies, and (iii) multianalyte recognition process means for detecting and discriminating amplified nucleic acid sequences which incorporate nucleic acid sequence mismatch detection means for differentiating minor mismatches between multiple amplified nucleic acid sequences, including only single base mismatc…
