2. gold number
Answers
Electrophoresis is a separations technique that is based on the mobility of ions in an electric field. ... Ions have different migration rates depending on their total charge, size, and shape, and can therefore be separated. The technique is used particularly for macromolecules, such as proteins.
Gold Number is a term used in colloidal chemistry. It is defined as the minimum amount of protective colloid in milligrams which prevents a colour change from red to violet of 10ml gold sol by the addition of 1 ml of 10%NaCl solution.
1. electroporesis
Electrophoresis is a technique commonly used in the lab to separate charged molecules, like DNA, according to size.An electric current is applied across the gel so that one end of the gel has a positive charge and the other end has a negative charge. The movement of charged molecules is called migration.
