Abstract :

Protein puri cation is an essential, primary step in numerous biological studies, including a rapidly emerging proteomics  eld, its structural counterpart and drug screening. Moreover, puri cation with high yield, purity and activity (HHHpuri  cation) is compulsory for high-resolution structural analysis and industrial protein production. Apparently, a universal, one-step high-throughput approach for HHH-puri cation is a key, yet unachievable, factor of success for all these crucial studies/applications. We designed and implemented an original chromatographic technology based on the physiological, ultrahigh a nity (Kd~10-14-10-17 M) small (~10/16kDa) protein/protein complex, which allows for a one-step HHH-puri cation of the traditionally challenging (eukaryotic, membrane, multi-subunit, DNA/RNA-binding, toxic) proteins.  e developed system is practically inde nitely reusable, suitable for industrial-scale manufacturing, has high capacity (up to 20mg tagged protein per ml beads) and e ciently operates under nearly identical (target-independent) basic conditions. Altogether, it provides major advantages over the existing commercial analogs and may form a solid high-throughput platform for both, puri cation and associated â�?�?a nityâ�? techniques (pull-down, kinetic activity/binding assays, etc.) of protein characterization.
