Coimmunoprecipitation

Coimmunoprecipitation is a laboratory technique used to study how proteins interact with each other. It involves using an antibody that specifically binds to one protein of interest. When the antibody attaches to this target protein, it pulls it out of a mixture along with any other proteins attached to it. This allows scientists to identify and analyze those interacting proteins, helping to understand complex biological processes and protein functions within cells. Essentially, it's like fishing for a specific protein and seeing what other proteins come along for the ride.
