    摘要: A method and a kit for detecting a target protein in a sample with a signal amplification strategy are provided. The signal amplification strategy is established for the aptamer-based molecular recognition of a target protein with concomitant release of single-stranded DNA (G-DNA), which binds complementarily to a single-stranded RNA comprising a fluorophore and a quencher (“F-RNA-Q”). The fluorescence-quenched RNA is then degraded by RNase H to result in a fluorescence signal, and the undamaged G-DNA is recycled to yield fluorescence amplification.

    摘要: The present invention relates to a method for quantitative analysis of interactions between fluorescein-labeled HIF-1α (alpha) C-terminal peptides and cAMP-responsive element binding protein (CBP) or p300 proteins, and a method of screening inhibitors against the formation of HIF-1α-p300 or HIF-1α-CBP protein complexes using the above method.Therefore, the fluorescence polarization (FP) measurement method of the present invention is useful for systemically evaluating the HIF-1α-CBP or HIF-1α-p300 interactions, and examining the effects of posttranslational modifications (hydroxylation, S-nitrosylation, and phosphorylation) of the C-TAD peptide of HIF-1α on the recruitment of p300.
