Abstract

A microchip that integrates the sol-gel affinity column of a SELEX system is de-veloped. This microchip includes electric heaters for individual heat elution from sol-gels which contain target molecules. To test the microfluidic system for SELEX compatibility, a known aptamer targeting TBP was delivered, then eluted from sol-gels and collected for RT-PCR. We also demonstrated the multiplex SELEX in this microfluidic system by well-defined aptamers that bind either TBP and TFIIB. We could specifically bind and elute the corresponding aptamers from each target pro-tein sol-gel. Comparing to the conventional SELEX, our microfluidic SELEX sys-tem improved cycle efficiency by 2 cycles.
