Anti-Human Magnetic Beads

Superparamagnetic nanoparticles coupled with Goat anti-Human IgG and utilized in the magnetic separation and isolation of human antibodies from serum or human antibody-labeled components.


Product Specifications

  • IgG


Anti-Human IgG Magnetic Beads are densely coated with Goat anti-Human IgG. They are utilized in the magnetic separation and isolation of human antibodies from serum or human antibody-labeled components.

The magnetic beads are incubated with a sample containing antibodies and then held by a magnet next to the tube. After the unbound contaminants are washed from the beads, the bound antibodies are eluted from the beads with an elution buffer (not provided). With the magnet immobilizing the beads, the eluted antibodies are transferred to a new tube.

Magnetic Beads are superparamagnetic, non-aggregating iron oxide particles (or "microspheres") for capturing or purifying targets such as proteins, antigens, antibodies, DNA/RNA, cells, and more. The design enables faster binding kinetics, with high sensitivity & selectivity, in many biomedical and research applications, including automated HTS and manual applications.

Superior yield, purity, and quality over the leading competitors, all at a better value, because we design and manufacture them in-house.

Product Features

Storage and Stability

Ice packs
The Goat anti-Human IgG Magnetic Beads should be stored in the refrigerator (4-8°C). The reagent must be allowed to reach room temperature (20-25°C) before use and may be used until the expiration date on the box. Do not freeze, dry, or centrifuge the beads as they may result in loss of binding activity and aggregation
Product works very well for Phage Display techniques. Bound tightly with Anti-human Fc.
