No, iodine is not a basic stain. Iodine is commonly used in Gram staining to identify bacteria as either Gram-positive or Gram-negative based on their cell wall composition. It acts as a mordant in the staining process and helps to fix the crystal violet stain in Gram staining.
You can remove an iodine stain from the skin by washing the affected area with soap and water. If the stain persists, you can try using rubbing alcohol or an iodine stain remover. It's important to wash the area thoroughly to prevent skin irritation.
Nonstaining iodine is a type of iodine solution that does not contain iodine in a free form that can bind to skin proteins, which is why it does not stain the skin. This means that it is less likely to leave a visible mark on the skin compared to traditional iodine solutions.
Iodine is used to stain cells because it binds to glycogen and starch, making them more visible under a microscope. This helps to visualize the cellular structures and identify specific components within the cell.
Tincture iodine in trichrome stain is used as a mordant to enhance the staining of collagen fibers. It helps to improve the contrast and visibility of collagen in the tissue sample.
Iodine stains starch molecules blue-black. This is commonly used in biological staining techniques to visualize starch content in cells or tissues.

To stain onion peel cells, you should use a stain called iodine. Iodine is commonly used to stain cells because it binds to starches and glycogen in the cells, making the cells more visible under a microscope.
The iodine stain solution you're referring to might be Lugol's iodine. This is iodine and potassium iodide in water. The product available in a pharmacy is tincture of iodine which is iodine and potassium iodide in ethanol and water. Please see the links.
It is crystal violet & stains all cells purple.
I just did a lab in biology called "How Plant and Animal Cells Differ" and in the packet it had that question. The answer is: Lugol's iodine stain stops the activity of the cell. It kills whatever specimen it is staining.
Nonstaining iodine is a type of iodine solution that does not contain iodine in a free form that can bind to skin proteins, which is why it does not stain the skin. This means that it is less likely to leave a visible mark on the skin compared to traditional iodine solutions.
Iodine is used after the primary stain in the Gram stain procedure to form a complex with the crystal violet dye, which helps to stabilize the dye within the bacterial cell wall. This step enhances the retention of the primary stain in Gram-positive bacteria.
one disadvantage of using iodine to stain cells is that iodine will kill living cells.
A simple stain like iodine can make cell parts show up that would otherwise be nearly invisible since they are colorless.A simple stain like iodine will reveal a cell's morphology.
Iodine is used to stain cells because it binds to glycogen and starch, making them more visible under a microscope. This helps to visualize the cellular structures and identify specific components within the cell.
Iodine is used to bind the Crystal Violet to the Gram Positive microbes.
Iodine. If you ever get iodine on your clothing, it will leave a permanent stain because of the starch.
