DAPI: a DNA-specific fluorescent probe.
DAPI (4',6-diamidino-2-phenylindole) is a DNA-specific probe which forms a fluorescent complex by attaching in the minor grove of A-T rich sequences of DNA. It also forms nonfluorescent intercalative complexes with double-stranded nucleic acids. The physicochemical properties of the dye and its complexes with nucleic acids and history of the development of this dye as a biological stain are des...
متن کاملDAPI derivative: a fluorescent DNA dye that can be covalently attached to biomolecules.
The preparation of a DAPI (4',6-diamidino-2-phenylindole) derivative is described. The resulting derivative retains the fluorogenic property upon binding to double-stranded DNA. Its ability for bioconjugation through amide linkage is demonstrated.
متن کاملSingle-molecule force spectroscopy distinguishes target binding modes of calmodulin.
The eukaryotic signaling protein calmodulin (CaM) can bind to more than 300 known target proteins to regulate numerous functions in our body in a calcium-dependent manner. How CaM distinguishes between these various targets is still largely unknown. Here, we investigate fluctuations of the complex formation of CaM and its target peptide sequences using single-molecule force spectroscopy by AFM....
