    Staining is to improve the contrast within a cell to show the organelles in greater clarity and detail. The cytosol is transparent there is little if any contrast. Using positively charged dye it attracts to the cytosol within the cell and you can distinguish between the different organelles. Using a negatively charged dye it repels the outside of the cell and stays outside the cell and distinguishes the cell from the background. The positive dye could be Methylene blue and the negative dye could be Congo red. Differential staining is used to differentiate between two different organelles or organisms. Gram stain technique is used to show gam positive bacteria and gram negative bacteria whilst the acid fast technique is used to show mycobacterium form other bacteria present.

    How come when I apply the alcohol most of my specimens come out red, even something like gram positive bacillus subtilis comes out half red half blue and sometimes completely red. Professor said that could happen if I'm applying too much alcohol but I do it as instructed, until it runs clear. Could it be that my school has such old specimens that all the peptidoglycan is long gone and alcohol just washes everything away?

  • @VanillaSnake21

    I can answer this now that I've finished the semester, by the end I was able to do perfect Gram stains. The reason it could sometimes comes out mixed color or the blue color washes off completely is mostly due to uneven alcohol coverage. You have to place the drop of alcohol all the way at the top of the slide and let it slide down on it's own, also don't follow the directions "until it runs clear" once you see that it's light blue it's fine to stop. It's just a matter of getting the amount and the coverage right. By the way, got an A+ in this class, due in part to videos such as these. Many thanks.
