摘要:
A method of increasing the specificity of nucleic acid hybridization, comprising hybridizing nucleic acid in a solution containing a zwitterionic compound selected from the group consisting of 3-(cyclohexylamino)-1-propanesulfonic acid (CAPS), 3-[(3-cholamidopropyl)dimethylammonio]-1-propane sulfonate (CHAPS), 3-(cyclohexylamino)-2-hydroxy-1-propane sulfonate (CAPSO), and 2-(cyclohexylamino)ethane sulfonate (CHES) is provided. The method allows a reduction in the yield of non-specific amplification products in multiplex PCRs while maintaining the yield of target amplification products.

Provided is a microfluidic device that can automatically perform various types of biological blood analysis. In the microfluidic device, a specimen is centrifugally separated and the centrifugally separated specimen is diluted into various dilution ratios. Also, at least two reagents that are required for one reaction and that need to be separately stored are stored in separate chambers, and they are mixed when a reaction is needed. Thus, various conventional blood analyzing reagents can be used as they are or after being minimally processed in the microfluidic device.
