Ionic strength measurement

WebEffect of ionic strength on antigen-antibody reaction is particularly important in blood group serology. Here the reaction is significantly influenced by sodium and chloride ions. For example, in normal saline solution, Na+ and Cl− cluster around the complex and partially neutralize charges, potentially interfering with antibody binding to antigen. WebIonic Strength of Medium The ions in the medium and the total ionic concentration can affect the particle diffusion speed by changing the thickness of the electric double layer called the Debye length (K-1). Thus a low conductivity medium will produce an extended double layer of ions around the particle, reducing the diffusion speed and
