Immunoprecipitation Analysis Service

Immunoprecipitation analysis is a well-established technique used in protein research that employs specific antibodies to selectively enrich target proteins and their associated interaction partners. This method is essential for studying protein expression, post-translational modifications, and protein-protein interactions. As one of the core techniques in proteomics, immunoprecipitation analysis has been widely utilized in areas such as signal transduction pathways, disease mechanisms, and drug target identification.

 

MtoZ Biolabs offers high-efficiency and precise immunoprecipitation analysis service, leveraging advanced instrument platforms and the expertise of our professional team. Our end-to-end solutions encompass the entire immunoprecipitation analysis workflow, from experimental design to data interpretation, empowering clients to quickly and comprehensively uncover protein functions and interactions in complex biological systems.

 

Technical Principles

Immunoprecipitation analysis relies on the high-affinity and specificity binding between antibodies and their target proteins. In the experimental process, specific antibodies form stable complexes with target proteins and their interacting molecules, which are then captured using magnetic or agarose beads (e.g., Protein A/G beads) to selectively enrich the target proteins from complex biological samples. After several washing steps to remove nonspecific bindings, high-purity target protein complexes are obtained through optimized elution conditions. These complexes can then be analyzed using techniques such as western blot, ELISA, functional assays, or mass spectrometry to gain deeper insights into molecular characteristics and interaction networks.
