CHAPTER ONE INTRODUCTION/LITERATURE REVIEW THE ERYTHROCYTES A cell that contains haemoglobin and can carry oxygen to the body. Also called a red blood cell (RBC). The reddish colour is due to haemoglobin. Erythrocytes are biconcave in shape which increases the cells surface area and facilitates the diffusion of oxygen and carbon dioxide. This shape is maintained by a cytoskeleton composed of several proteins. Erythrocytes

Objectives Protein Isolation: Protein isolation for a western blot uses detergents and mechanical force to separate seeded cells from their container. Eukaryotic cells are attached to the surface of a flask by cadherins. In the past‚ we’ve separated the cells from the flask by breaking these bonds with a protease‚ but in order to keep the proteins intact‚ a different method needs to be used to extract the proteins. In protein extraction for a western blot‚ we use detergents to lyse the membrane

Elasticity is the ability of an object or substance to return quickly to its original shape and size after being bent‚ stretched‚ or squashed. When an elastic material is deformed due to an external force‚ it experiences internal forces that oppose the deformation and restore it to its original state if the external force is no longer applied. There are various elastic moduli‚ such as Young’s modulus‚ the shear modulus‚ and the bulk modulus‚ all of which are measures of the inherent stiffness of
