Protein Composition in Red Blood Cells in Humans using Polyacrylamide Gel Electrophoresis Name: Emma Claypole Date: Wednesday March 16, 2016 Lab Group: W08, Wednesday morning 2 Abstract The proteins of Bovine red blood cell (RBC) membranes were analyzed using polyacrylamide gel electrophoresis. After analyzing Bovine RBC they were then compared to human RBC counterpart. Following finding the log of each molecular weight of each band, band one showed the highest molecular weight. All five bands viewed were from humans. There are typically 7 bands visible however, in our case only five were visible due to implications within the gel sample. Introduction Proteins are important elements in cellular membranes and give the membranes many of their characteristics. In red blood cells, the meshwork of proteins in and around the membrane gives it strength and flexibility, allowing a cell to squeeze through small capillaries without bursting. Other proteins play roles in transporting material in and out of the cell (Lab Manual, Cell Biology). Polyacrylamide gel electrophoresis (PAGE), with all of its different modifications is probably the most widely-utilized procedure in contemporary biochemistry and molecular biology (Mordacq and Ellington (1994)). In this experiment, we will attempt to determine the molecular weights of the major proteins in the plasma membranes of bovine red blood cells (RBCs). The predictions made are if our protein has similar weights as proteins
