Immunoglobulin E (IgE) is an antibody that is produced by the bodyâs immune system in response to a perceived threat. It is one of five classes of immunoglobulins (A, G, M, D, and E) and is normally present in the blood in very small amounts. This test measures the amount of IgE in the blood.mmunoglobulin E (IgE) is an antibody that is produced by the bodyâs immune system in response to a perceived threat.

For example, in paper chromatography water is the mobile phase and paper is the stationary phase. The solution's components ideally move at different speeds as they travel through the stationary phase so that they can be separated. Take one of the paper towel strips you prepared and place the pencil line you drew on top of the now-colored drop of water. Do you see the dye soak into the strip, coloring the area around the line? You can get some extra dye on the line by dabbing the sides of the wet candy with it.
Qualitative filter paper is also suitable for doing paper chromatography. An example of this can be seen if you click on the adjacent Technical Tab. Filter Paper-Ink Chromatography If you cut filter paper into a rectangular shape you can use it to do paper chromatography. Any of our sizes will do but most experiments can be done with the 70, 90 or 110mm sizes.
