Immunoprecipitation tools for your research
Immunoprecipitation (IP) is a quick, easy way to isolate your protein of interest from a complex mixture. Protein complex immunoprecipitation (Co-IP) uses the same technique to investigate protein-protein interactions within the cell, helping you determine changes to protein binding partners or complexes following cell treatment.
Antibodies with high specificity and affinity for their target protein are essential for successful IP and Co-IP experiments. With our broad range of recombinant monoclonal antibodies and IP reagents, you can be confident that your IP results will be reliable and reproducible, helping your research move forward faster.
Recombinant rabbit monoclonal antibodies for IP
Our recombinant antibodies have unrivaled batch-to-batch consistency and confirmed specificity, giving you results you can trust first time, every time, over time. We know the quality of your reagents matters, so we subject our antibodies to industry-leading validation processes, including knock-out validation.
