Abstract
Abstract Phosphatase of regenerating liver 3 (PRL3), which belongs to the superfamily of protein tyrosine phosphatases (PTPs), represents a group of low molecular weight PTPs that participate in tumorigenesis and metastasis processes. Presented here are the results of cloning, prokaryotic expression, purification, and polyclonal antibody preparation of PRL3. To obtain a specific polyclonal antibody against PRL3, the authors have prepared GST-PRL3 to immunize rabbits and purify an anti-PRL3 polyclonal antibody by negative selection affinity columns. Western blot analysis shows that the anti-PRL3 polyclonal antibody has a specific binding ability with PRL3 protein. The anti-PRL3 polyclonal antibody provides a good tool to further study the function of PRL3.
