What is locating agent used for?
Locating agent is a substance/liquid that help to separate and analyze colorless substances in chromatography by reacting with the colorless substance to form colored spots on the chromatogram.
How can proteins be analyzed by chromatography?
A solution of amino acids is spotted onto a piece of chromatography paper which is then placed into a container filled with a suitable solvent. A dye is used so that the position of the amino acids along the piece of paper can be seen. The distances travelled by the amino acids are measured to calculate their retention factors (Rf) values. These are then compared to known standards.
What types of amino acid screening tests are performed?
Two types of amino acid screening tests are used together to diagnose amino acid disorders.Blood plasma screening.Urine test.Both these tests use thin layer chromatography to separate the amino acids present.
How is chromatography used in everyday life?
some applications are; "Separations of inks, amino acids" from a mixture , blood and urine anlysis, from a mixture
What do heliocases do?
separate strands of nucleic acids (unwind DNA)
How do you separate amino acids from fatty acids?
Amino acids are soluble in water and fatty acids are not.
Which method is commonly used to separate and identify amino acids?
chromatography

When the amino acids are colourless how will you get to know that which acid is this?
It really depends on the type of chromatography. E.g. with thin layer chromatography, UV light is used, and the amount of light that is absorbed is measured, and they can tell the amino acid from this. In paper chromatography, a substance called ninhydrin is sprayed onto the separated amino acids and they become visible.
