Final answer:
Co-immunoprecipitation is a technique used to study protein-protein interactions. It involves precipitating a target protein along with its interacting proteins using specific antibodies.
Step-by-step explanation:
Co-immunoprecipitation is a laboratory technique used to study protein-protein interactions. It involves the precipitation of a target protein along with its interacting proteins using specific antibodies. In this technique, a sample containing the target protein is incubated with antibodies that recognize the target protein. The antibody-protein complexes are then precipitated out of the solution using a technique such as centrifugation. The precipitated complexes can then be analyzed to identify the interacting proteins.
