This is a fluorescent slide I made of a developing fruitfly larva, stained with phalloidin. Phalloidin selectively stains the protein actin, which is found particularly in muscles, but as you can see it is also found in numerous other tissues.
DONATIONS: I take these photos for my wallpapers in my spare time. I don't make much money in my day job, and any donations are appreciated. If I got enough, perhaps I could get a better camera to make wallpaper with! Whether you donate or not, please enjoy this wallpaper!
