Labeling nuclear DNA with hoechst 33342.
A number of fluorescent stains are available that label DNA and allow easy visualization of the nucleus in interphase cells and chromosomes in mitotic cells. One advantage of Hoechst 33342 is that it is membrane permeant and, thus, can stain live cells. Hoechst 33342 binds to adenine-thymine-rich regions of DNA in the minor groove. On binding to DNA, the fluorescence greatly increases. This pro...
متن کاملRole of topoisomerases in cytotoxicity induced by DNA ligand Hoechst-33342 and UV-C in a glioma cell line.
DNA ligand Hoechst-33342 significantly enhances UV induced cytotoxicity in human glioma cell lines (BMG-1 & U-87) with supra additive increase in cell death, cytogenetic damage, cell cycle delay, apoptosis and inhibition of PLDR. Cytotoxicity of Hoechst-33342 arises due to its interference in the breakage-rejoining reaction of DNA topoisomerases by stabilization of cleavable complexes. Since to...
متن کاملLabeling Adipose-Derived Stem Cells with Hoechst 33342: Usability and Effects on Differentiation Potential and DNA Damage
Adipose-derived stem cells (ASCs) have been extensively studied in the field of stem cell research and possess numerous clinical applications. Cell labeling is an essential component of various experimental protocols and Hoechst 33342 (H33342) represents a cost-effective and easy methodology for live staining. The purpose of this study was to evaluate the labeling of rat ASCs with two different...
متن کاملCross-linking of histone proteins to DNA by UV illumination of chromatin stained with Hoechst 33342.
The photochemical effects of near-UV light on chromatin labeled with the vital DNA dye Hoechst 33342 (H33342) are studied. Several types of experiments demonstrate that illumination at both 365 and 410 nm results in significant cross-linking of proteins with the DNA. Fluorescence microscopy of dye-stained Xenopus XTC-2 nuclei shows that UV illumination has effects similar to chemical fixation b...
متن کاملEffects of Hoechst 33342 on C2C12 and PC12 cell differentiation.
Accumulative evidence demonstrates that normal as well as cancer stem cells can be identified as a side population following Hoechst 33342 staining and flow cytometric analysis. This popular method is based on the ability of stem cells to efflux this fluorescent vital dye. We demonstrate that Hoechst 33342 can affect cell differentiation, suggesting potential complications in the interpretation...
