MagSi-proteomics beads from AMS Biotechnology are magnetic beads 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 support for assays and procedures based on affinity purification. Instrumentation is available to mix, incubate, and separate the magnetic beads in 96-well plates without columns or centrifugation.
The beads bind and elute sample fractions. Peptide amounts as low as 20 to 50 ng can be desalted by MagSi proteomics C8 and C18 beads and analyzed. Applicable for manual and automated/robotic fractionation, the beads will collect in less than one minute when magnetic force is applied.
