C. Pull-down Assays A pull-down assay is similar in concept to a Co-IP because it is performed in order to investigate proteins or ligands that bind to a known bait protein. The assay is performed either to prove a suspected interaction between two proteins or to investigate unknown proteins or molecules that may bind to a protein of interest.

Frank H. Stephenson, in Calculations for Molecular Biology and Biotechnology (Third Edition), 2016 Abstract. Centrifugation is a method of separating molecules having different densities by spinning them in solution around an axis (in a centrifuge rotor) at high speed. It is one of the most useful and frequently employed techniques in the molecular biology laboratory.
