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. WebThe weight or amount of balls in this analogy is the ionic strength and most often measured in KH (or alkalinity) it’s the third dimension in understanding pH. As you can …
