Function 16 October 2014 Gel Filtration and Electrophoresis Objective The essential goal of the experiment was to separate proteins in a solution based on size in different fractions. The relative protein content for each one fraction was found through the utilization of an amido black-based protein assay. Later in the trial polyacrylamide gel electrophoresis was utilized to separate BSA from hemoglobin. Methods I. Gel Filtration and Protein Assay: 1. A slurry of Bio-Gel P-100 beads in water was

Gel Electrophoresis Lab SBI4U1 May 13th‚ 2013 Gel Electrophoresis Lab Purpose: The purpose of this lab is to learn how restriction enzymes cut DNA molecules at specific sequences‚ thus producing DNA fragments of various lengths. Students learn how fragments form unique patterns‚ which help to distinguish the base for DNA identification. This lab answers the question “whose DNA was left behind?”. Materials: * Transfer pipets * Agarose Gel * Dyed DNA samples *

In gel electrophoresis‚ DNA fragments move through a porous matrix made of agarose‚ a gelatin-like substance purified from seaweed. The agarose is melted like Jell-O® and then poured into a plastic tray to harden into a slab called a gel. A plastic comb inserted at one end while the gel is hardening forms wells where DNA samples can be placed. The DNA is mixed with a loading buffer that contains glycerol—this makes it heavier than water‚ so it will sink to the bottom of the well. The gel is then

Agarose gel electrophoresis is a technique used in the laboratory to separate macromolecules such as nucleic acids and proteins. Electrophoresis can take a mixture of macromolecules of different molecular weights‚ shapes‚ and various electrical charges to determine all the various compounds in the mixture and allowing for further purification that can aid in details of individual elements of the mixture being studied. Agarose gel electrophoresis is a very important technique used in the field of

The two techniques that were used to create a DNA profile in this experiment were PCR and gel electrophoresis. The PCR is used to amplify the several DNA samples and gel electrophoresis is performed to separate the DNA fragments according to their size. [6] In the first part of the experiment‚ PCR amplification of the DNA templates was performed and the products obtained were used to perform gel electrophoresis. The process of PCR allows for the amplification of the DNA samples and the components needed

agarose gel electrophoresis in an emulation of DNA fingerprinting. The task‚ which was successfully carried out was to determine whether DNA from suspects A‚ B or C matches the sample of blood found at the murder scene (X). The process of PCR acts in the same way as DNA replication but is restricted to specific DNA samples of interest. By amplifying the necessary DNA sequence‚ this procedure is able to produce a usable DNA sample for agarose gel electrophoresis. Agarose gel electrophoresis is a method

The container in which the gel is stored has a negative and positive side; whichever side the DNA molecules go to means the DNA is charged the opposite way.

The picture above shows a typical gel electrophoresis set up. The clear container in the center of the picture is called a gel electrophoresis chamber. It contains the agarose gel that will be loaded with genetic material‚ as well as a buffer solution. It is connected to a DC power supply via electrodes. This picture was taken at Paw Print Genetics laboratory in Spokane‚ Washington. Viney and Fenton (1998) defined the term electrophoresis as‚ “the migration of charged particles through a static medium

OUTLINE What is PCR and Gel Electrophoresis? • Polymerase chain reaction (PCR) is a technique which is used to amplify the number of copies of a specific region of DNA‚ in order to produce enough DNA to be adequately tested. This technique can be used to identify with a very high-probability‚ disease-causing viruses and/or bacteria‚ a deceased person‚ or a criminal suspect. • Gel electrophoresis is a widely used technique for separating electrically charged molecules. It is a central technique
