Immuno Magnetic Microspheres

Immuno Magnetic Microspheres are magnetic beads covalent coated with bio-macromolecules. We provide two series of products modified with common used protein types: Streptavidin (SA) and Protein A/G. They are widely used in applications such as:

Immuno-precipitate antigens (using biotinylated antibodies) from a wide variety of sources

Capture protein-protein interactions in pull-down assays using biotinylated "bait" proteins

Isolate biotinylated DNA-protein complexes from cell or tissue extracts

Capture single-stranded biotinylated DNA oligos

Isolate biotinylated PCR products

Benefits:

Protein A/G Type

Isolates IgA and IgG proteins in a single step instead of running two separate processes

Presence of protein A/G binding sites accommodates broadest range of antibody species and sub-classes
