Product Name

Protein G magnetic microspheres

 Product Overview

Protein G magnetic beads are high-performance affinity particles used in biomedical research, primarily for antibody purification and immunoprecipitation methods. They are typically made of superparamagnetic material and are coated with recombinant Protein G, a protein that specifically binds a wide range of mammalian IgGs.

 

Technical Parameter

Concentration: 30 mg/mL

Solvent: water

Diameter: ~1um

SPA load : 70-85ug/mg

Surface potential:~- 26 mV

Magnetic content: 35%-45%

Product Features

High capacity: high binding capacity, low sample volume per experiment . 

Low non-specific binding: Stable pre-enclosed magnetic beads provide high purity products. 

Flexibility: One bead contains both IgG binding domains of protein G, which is convenient to use.

Application Fields

Immunoprecipitation (IP) and Co-immunoprecipitation (Co-IP) assays: Protein G beads can be used to precipitate specific antibodies or their complexes from samples from a wide range of species, including mice, humans, rabbits, ewes, goats and sheep. 

Antibody Purification: Particularly useful for purifying antibodies, including many IgG subclasses, from serum, cell culture supernatants or ascites.  

Chemical cross-linking: antibodies can be immobilised onto magnetic beads using chemical cross-linkers to avoid IgG contamination in IP or Co-IP experiments, creating reusable immunoprecipitation beads.

Related Information

Sealed, avoid light, and keep at 4¡ãC Expiry date: Six months before unsealing.
