摘要
(Figure Presented) Superdetective: The detection of 180 molecules of a protein was achieved by amplification of DNA aptamers that bind to the target protein. The protein-aptamer complex is separated from the unbound aptamer by capillary electro-phoresis (CE). The complex fraction is collected and the aptamer amplified by the polymerase chain reaction (PCR). Such amplification dramatically improves the sensitivity of the detection of proteins. © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
