WebJul 9, 2024 · For FISH staining, stain the intestinal sections as soon as possible (i.e., within a few weeks of sectioning) to achieve a strong FISH signal. If omitting FISH staining, lectin + DAPI staining can be performed on less fresh (i.e., months-old) samples without significant loss of signal. 3. Staining bacteria and host features. Preparation WebMay 5, 2024 · Although the intensity of bacterial LPS and LTA staining was very strong in CD45+/CD68+ cells, bacterial 16S rRNA was only rarely found in macrophages by FISH (Fig. 2, ,A A and andD, D, and figs.
