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

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

AGAROSE GEL ELECTROPHORESIS Gel electrophoresis is a widely used technique for the analysis of nucleic acids and proteins. Most every molecular biology research laboratory routinely uses agarose gel electrophoresis for the preparation and analysis of DNA. We will be using agarose gel electrophoresis to determine the presence and size of PCR products. Background: Electrophoresis is a method of separating substances based on the rate of movement while under the influence of an electric field

In this experiment we used gel electrophoresis to separate goat‚ sheep‚ cow‚ horse‚ chicken serum along with cow transferrin and cow gamma globulins. In this lab we successfully prepared the gel electrophoresis bed and successfully separated the proteins. The western blot along with the nitrocellulose blot was successful but produced no visible results. Introduction: Amino acids are basic units and building blocks of proteins. They consist of an amine group‚ a carboxylic group and side chain.

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 *

Gel Electrophoresis Adventure Intro The final goal of this lab was to successfully measure the size of different samples of DNA by placing each sample into a well in agarose gel and running a current through a charged chamber. The DNA samples will move through the gel towards the positive charge. Ideally‚ the DNA will move and create and sequence of smallest to largest. This lab exposes us to DNA technology.
