Product Information
Description: Hoechst S 769121 (Nuclear yellow) is a DNA-selective dye that is used to label DNA content in live and fixed cells. Upon binding to DNA, nuclear yellow fluoresces, and this fluorescence can be measured using fluorescence microscopy, microplate fluorometry, or flow cytometry. Nuclear yellow displays excitation/emission maxima of 355/495 nm, respectively.
   
Stability and Solubility Advice: Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide.
We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details.
