一般說明

Cell-permeable DNA-binding dye. Binds preferentially to DNA rich in adenine and thymine. Used in flow cytometry for measuring nuclear DNA content or for sorting isolated chromosomes. Useful for microscopic detection of nuclei and nuclear DNA in normal and apoptotic cells. Can also be used to detect mycoplasma. A reversible inhibitor of S-adenosyl-L-methionine decarboxylase and diamine oxidase. Cells are typically stained at 1 µg/ml.
Cells are typically stained at 1 µg/ml.

應用


  • Determination of Ploidy Levels and Nuclear DNA Content in Cryptococcus neoformans by Flow Cytometry: Drawbacks with Variability: This research utilizes DAPI for quantifying nuclear DNA content and determining ploidy levels in Cryptococcus neoformans, providing critical insights into fungal genetics and potential challenges in reproducibility (Chang et al., 2024).

  • Near-Infrared Light-Excited Quinolinium-Carbazole Small Molecule as Two-Photon Fluorescence Nucleic Acid Probe: Highlights the development of a novel two-photon fluorescence probe for nucleic acid imaging, employing DAPI as a reference for comparing fluorescence characteristics, enhancing molecular imaging techniques (Sun et al., 2024).

  • A FACS-based Novel Isolation Technique Identifies Heterogeneous CTCs in Oral Squamous Cell Carcinoma: Applies DAPI for the enumeration and characterization of circulating tumor cells (CTCs), showcasing its importance in cancer diagnostics and the potential for personalized medicine approaches (Chauhan et al., 2024).
