Particle- oder Bead based Assays work similar to ELISAs, they only use another surface where the antibody binds. Instead of immobilizing on microtierwells the surface of tiny round silica beads is used. This increase of surface allows to minimize the testvolume, few microlitre are sufficient. Additonally u can divide the beads in groups to and analyse different substances at onces(multiplex-arrays).
Cross-linked polymers (resins) represent the solvents for solid-phase organic reaction like the synthesis of peptide chains. If you need help, please contact our customer support via phone, live chat or email. More information about magnetic beads. More information about peptide synthesis.
