ELECTRICAL CONDUCTIVITY - Cerritos College
www.cerritos.edu3. Electrical conductivity of compounds in aqueous solutions Water is a good solvent for many covalent and ionic compounds. Substances that dissolve in water to form electrically conducting solutions are electrolytes. Substances that dissolve to form nonconducting solutions are known as nonelectrolytes. All soluble ionic compounds are electrolytes.

Effective Blocking Procedures in ELISA Assays
www.corning.coma blocking reagent — a collective term for various substances that are used to reduce NSB without taking an active part in specific assay reactions. (Other factors can influence NSB, such as protein-protein interactions that are unique to each ELISA system, and must be considered during assay development and optimi-zation).
