2010年,沃特世推出了1.7µm的ACQUITY UPLC Protein BEH SEC色譜柱,用于在沃特世低擴(kuò)散的UPLC儀器上獲得性能。與傳統(tǒng)的5-8 µm SEC色譜柱相比,ACQUITYUPLC Protein BEH SEC色譜柱在更短時(shí)間內(nèi)表現(xiàn)出了的組分分離度。2015年開(kāi)始,沃特世相繼推出化學(xué)性質(zhì)一致的XBridge Protein BEH SEC125?、200?和450?, 3.5, 2.5 µm色譜柱,可在常規(guī)HPLC平臺(tái)上提供相當(dāng)?shù)慕M分分離度。
Analysis of Biomolecules by Size- Exclusion UltraPerformanc e Liquid Chromatography
In the production of biopharmaceuticals, there may be different analytical requirements for groups performing clone section, formulations and stability, and quality control (QC). Depending on the goal of the separation, methods may be optimized for fast analysis time, highest possible resolution, and/or reproducibility. Size-exclusion (SEC) chromatography is often used throughout the biopharmaceutical production process for the analysis of proteins and their aggregates. While SEC has traditionally been used in conjunction with low pressure HPLC instrumentation, the advent of UPLC® Technology and new sub-2 µm packing materials allows for substantial improvements in chromatographic resolution and throughput. This application note will demonstrate the use of the new ACQUITY UPLC® SEC solution for the improved detection and/ or faster analysis of protein aggregates in biopharmaceuticals.
