Dapi staining troubleshooting
WebDapi stain emits at 488, We are staining with DAPI and alexa-488 and get a VERY strange bleed through. 1. We illuminate with 488 and observe cytoplasmic staining (nothing in the nucleus). 2. We then illuminate with UV light from the HBO and observe a nice DAPI stain. 3. If we then re-illuminate with the 488 laser, the nucleus is now lit!

Web1 hour ago · DAPI staining (gray) is only visible within the granular cell layer, while a majority of the staining by NbPSD95 and the anti-Syt1 antibody are found on the molecular layer. In addition, NbPSD95 gives a bright signal in the Purkinje cell layer at the axosomatic synapses directly contacting the cell body of Purkinje cells (arrowheads). WebMar 15, 2024 · H&E. H&E is the most commonly used of all the various staining methods available in frozen section. H&E is simple to perform, inexpensive and reliable. The two main dye components are hematoxylin and eosin. Hematoxylin is a natural dye derived from the Haematoxylon campechianum logwood tree, a tree native to Campeche’s Mexican …
WebMany researchers performing IF-ICC may wish to use a fluorescent reagent that marks the cell nucleus, such as DAPI or Hoechst. Because both of these intercalate to become fluorescent within seconds of accessing the DNA, mounting medium that contains DAPI can be used to achieve nuclear stain and mounting in a single step. WebFeb 23, 2024 · The fixed cells were immunostained with rabbit anti-MBP (1:500, Abcam, Cambridge, UK). The cells were imaged with an Olympus fluorescence microscope using a 20× objective lens. The cell that was immunopositive for MBP and counterstained with an intact cell nucleus (DAPI positive staining) was identified as a MBP positive cell.
WebWhen a sample stained with DAPI only was first imaged with the green filter set (FITC/GFP), only a weak cytoplasmic autofluorescence was observed. Next, we imaged the … WebDAPI staining is normally performed after all other staining. 1. Pellet cells by centrifugation and resuspend the cells in buffered salt solutions or media, with optimal dye binding at pH 7.4. 2.
