Abstract

Immunoprecipitation (IP) is a routine method to detect protein binding and interactions. But the weak binding between two proteins is often hard to detect during regular IP procedure. This protocol offers a crossliking and IP combination method to detect weak binding of proteins in zebrafish embryos.
