Nucleic acid probes aptamers

Fluorescence-based assays employ reagents to characterize a wide range of cellular components, including nucleic acids, proteins, biogenic amines, carbohydrates, and lipids. These assays are often based on affinity probes, such as oligonucleotides, antibodies, aptamers, and lectins, which are used to characterize a specific component within the cell. In addition, fluorogenic substrates are used to characterize enzyme activity in single cells.
