Protein self-interaction chromatography on a microchip

Author affiliations


This paper presents the development of a novel miniaturized experimental procedure for the measurement of proteinprotein interactions through Self-Interaction Chromatography (SIC) on a microchip, without the use of chromatographic resins. SIC was recently demonstrated to be a relatively easy method to obtain quantitative thermodynamic information about proteinprotein interactions, like the osmotic second virial coefficient B22, which relates to protein phase behavior including protein crystallization. This successful miniaturization to microchip level of a measurement device for protein self-interaction data is a first key step to a complete microfluidic screening platform for the rational design of protein crystallizations, using substantially less expensive protein and experimentation time.
