Abstract
The present teachings are directed to compositions, methods, and kits for amplifying target nucleic acids while reducing non-specific fluorescence and undesired amplification products, sometimes referred to as secondary amplification products or spurious side-products. The enzyme inhibitors disclosed herein comprise a nucleotide sequence and at least one quencher. Complexes comprising an enzyme inhibitor associated with an enzyme, wherein at least one enzymatic activity of the enzyme is inhibited, are also provided. Methods for amplifying a target nucleic acid while reducing undesired amplification products are disclosed, as are methods for reducing non-specific fluorescence. Kits for expediting the performance of certain disclosed methods are also provided.
