Beckman Coulter, Inc. introduces IgY-R7 Rodent and Single-Component Chemistries to its family of ProteomeLab™ Partitioning Systems, for the isolation and analysis of protein-based biomarkers. The new IgY-R7 Rodent Chemistry selectively partitions seven highly abundant proteins – up to 70 percent of the protein mass – from rat or mouse serum or plasma. The new Single-Component kits specifically capture a choice of seven key highly abundant plasma proteins, enabling a more targeted approach for specific protein partitioning.
