FluoCells® prepared slide #4 (Cat. no. F24631) contains a section of mouse intestine stained with a combination of fluorescent stains. Alexa Fluor® 350 wheat germ agglutinin (Cat. no. W11263) is a blue-fluorescent lectin that was used to stain the mucus of goblet cells. The filamentous actin prevalent in the brush border was stained with red-orange–fluorescent Alexa Fluor® 568 phalloidin (Cat. no. A12380). Finally, the nuclei were stained with SYTOX® Green nucleic acid stain (Cat. no. S7020). This image is a composite of three digitized images obtained with filter sets appropriate for fluorescein, DAPI and tetramethylrhodamine.
