MAGNETIC BEADS

摘要

MagSi-proteomics beads are magnetic beads that are an ideal tool for the purification, concentration, and desalting of peptides and protein digests. The surface of the beads has been modified with C4-, C8-, and C18-alkyl groups that are optimized for reversed phase applications. Magnetic beads offer a convenient solid support for a variety of assays and procedures based on affinity purification. They are especially well suited for automated procedures because instrumentation is available to easily mix, incubate, and separate the magnetic beads in 96-well plates without columns or centrifugation. Offering higher throughput and cost efficiency compared to tip-based separations, MagSi proteomics beads efficiently bind and elute even tiny sample fractions. The high magnetic strength of MagSi beads makes them applicable for both manual and automated/robotic frac-tionation, because the beads will typically collect in less than one minute when magnetic force is applied.
