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.
PAPER CHROMATOGRAPHY This page is an introduction to paper chromatography-including two way chromatography. Carrying out paper chromatography Background Chromatography is used to separate mixtures of substances into their components.All forms of chromatography work on the same principle. They all have a stationary phase (a solid, or a liquid supported on a solid) and a mobile phase (a liquid or a gas).he mobile phase is a suitable liquid solvent or mixture of solvents. Producing a paper chromatogram You probably used paper chromatography as one of the first things you ever did in chemistry to separate out mixtures of coloured dyes-for example, the dyes which make up a particular ink.
