Capillary electrophoresis

Intro The technique of DNA profiling was first discovered in 1985 by Sir Alec Jefferys, a Leicester University geneticist. The work that he did in the laboratory led to the discovery of the technique for genetic profiling, which revealed a pioneer method of biological identification. A humans DNA can be found in hair, saliva, blood, and other various human properties. Sir Alec Jeffreys knew that what he had done was going to be revolutionary. After his discovery, he said “My life changed on…

Pollution is one of the most serious problems that affect our environment, and its effects on all life aspects are clear to everyone. Because of this, pollution is one of the most serious issues that all the word countries are concerned about. As time goes, the pollution problem increases and also the population growth increase. The increase in demand for water and food supplies place an increasing stress on the ground and surface water quality and quantity. One of the environmental problems…

were labeled Mix, Phe, Lys, and Ala (Figure 1). On the second plate, four marks were drawn, labelled as Mix, pH3, pH6, and pH11 (Figure 2) and this plate was then placed aside for use later in the experiment. The first plate was then spotted using capillary tubes and spotting a tiny drop of each amino acid on its labelled spot, then using the mixture to also make a spot on its mark. This plate was then sealed inside the developing jar and allowed to run until the solvent reached about ¾ of the…
