"SKi Bridge" Provides In-Line Coupling for Affinity Capture-Mass Spectroscopy

SKi Bridge Interface to Mass Spectrometry by Silicon Kinetics

Silicon Kinetics Inc., the innovative life sciences tool company which developed the world’s first 3D biosensor surface for label-free interaction analysis introduced a seamless fluidic/pressure interface between the Company’s SKi Pro™ instruments and mass spectrometers, for the AC-MS (affinity capture - mass spec) application. Earlier this year, the Company had announced the adoption of AC-MS by major pharmaceutical and biotechnology companies.

In AC-MS, only the molecules with the desired binding/release profiles are eluted directly into a mass spectrometer, through a fluidic interface called SKi Bridge. “SKi Bridge brings unparalleled ease to the combining of label-free binding with MS detection,” said John Ervin, PhD, President. “Most current AC-MS customers use it to perform high throughput screens of small molecule binding, which would be impossible with other label-free instrumentation. AC-MS combines the sensitivity of label-free interaction analysis with the information richness of mass spectroscopy, in a fully in-line setup, useable up to 15,000 psi.”

The technology making affinity-capture and label-free detection possible on 3D silicon surface is NPOI, or nano-pore optical interferometry, by Silicon Kinetics.

About Silicon Kinetics

Silicon Kinetics Inc. is a privately-held life sciences tools company headquartered in San Diego, California. The Company specializes in instruments for optical interferometry on nano-porous silicon biochips. The SKi Pro™ instrument platform and the 3D SKi Sensor™ biochips are used to detect protein-protein, protein-drug, or protein-DNA interactions in real-time and quantify binding kinetics, dissociation rates, or biomolecular affinity rankings, required for the study of disease pathways and the development and manufacturing of therapeutics.
