Invitrogen™ Dynabeads™ Protein G for Immunoprecipitation

Description

• Dynabeads Protein G beads are uniform, 2.8-μm superparamagnetic beads with recombinant Protein G (∼17 kDa) covalently coupled to the surface
• Dynabeads Protein G beads provide a great alternative to Sepharose resin or agarose resin for immunoprecipitation (IP) combined with your own antibody, and both manual and automated protocols are available
• Benefits of Dynabeads Protein G beads include: • Fast and easy —IP in less than 40 minutes with no columns, centrifugations, or time-consuming pre-clearing required • High performance —high target protein yield with low antibody consumption • Low background —very low non-specific binding with a high signal-to-noise ratio • High reproducibility —uniform beads ensure the most consistent results • Automation ready —automation protocols available with the KingFisher Sample Purification instruments Gentle separation causes minimal physical stress to proteins The magnetic separation technology utilized by Dynabeads Protein G is rapid and gentle, causing minimal physical stress to target proteins
• This permits the isolation and concentration of labile composites that might otherwise dissociate or be damaged by proteases during long incubation times
• Native protein conformation and large protein complexes are preserved
• Binding strength and antibody binding capacity Dynabeads Protein G beads allow for the isolation of most mammalian immunoglobulins (Ig)
• The amount of Ig captured depends on the concentration of Ig in the starting sample and on the type and source of the Ig
• 100 μL of Dynabeads Protein G will isolate approximately 25–30 μg human IgG from a sample containing 20–200 μg IgG/mL
• Predominantly Fc-binding allows optimal Ig orientation
• Dynabeads magnetic beads are not porous in nature such as Sepharose or agarose resins
• This means that all antibodies bind to the smooth outer surface of the beads and thus are available to bind the target protein
• This translates to a low antibody consumption while obtaining a high yield of the target protein
• The smooth bead surface is also responsible for the low non-specific binding that Dynabeads magnetic beads are known for
• Dynabeads immunoprecipitation protocol is fast and easy The manual IP protocol is simple and can be performed in less than 40 minutes with 3 easy bind-incubate-elute steps
• The procedure does not require any pre-clearing due to the low non-specific binding and uses very little antibody while still obtaining a high IP yield, thus saving both time and cost per IP
• The antibody-coated beads can be used in a variety of IP applications such as Co-IP, chromatin IP (ChIP/ChIP sequencing), RNA IP (RIP, RIP sequencing), small-scale IgG purification, and protein purification
• The isolated pure target protein can be used in downstream western blot, mass spectrometry analysis, sequencing, etc
• Automation-ready for use with KingFisher purification systems The 2.8-μm magnetic beads are ideal for high-throughput enrichment
• This process can be automated using any of our KingFisher sample purification systems or liquid handlers
• Commercial supply Our manufacturing sites are ISO 13485-certified
• Bead characteristics and manufacturing conditions help ensure consistency and batch reproducibility making them the ideal choice for commercial supply
