Protein Immunoprecipitation (IP), Co-Immunoprecipitation (Co-IP), and Pulldown Support
Explore the “Getting Started” and “Troubleshooting” sections for solutions to top inquiries and common problems. Browse through the “Guides and Tools” section to access comprehensive product-related support resources.
Getting Started
- What is the difference between immunoprecipitation (IP), co-immunoprecipitation (Co-IP), and pulldown assays?
- Should I use magnetic or agarose bead–based immunoprecipitation (IP) techniques?
- What is the difference between the Pierce™ Classic IP, Pierce™ Crosslink IP, and Pierce™ Direct IP kits?
- Is pre-clearing required when performing immunoprecipitation (IP) with Dynabeads™ Protein A and Dynabeads™ Protein G magnetic beads?
- How can I dissociate my biotinylated molecule from Dynabeads™ Streptavidin magnetic beads?
Troubleshooting
- I’m running a traditional immunoprecipitation experiment followed by western blotting. However, my target protein is migrating at the same molecular weight as the light or heavy chains of IgG. What should I do?
- I did an immunoprecipitation using one of your agarose resins. My tagged recombinant protein is not being enriched by the Pierce™ Agarose resin and seems to be stuck in the flow through. What should I do?
- What should I do when the antibodies coupled to Dynabeads™ Protein A or Dynabeads™ Protein G magnetic beads have lost function after crosslinking?
- What should I do if I get low binding to Dynabeads™ Protein A or Dynabeads™ Protein G magnetic beads?
- What should I do if I get nonspecific binding to Dynabeads™ Protein A or Dynabeads™ Protein G magnetic beads?
