Designing an IHC experiment for ID3? The guide has the expected staining pattern, antigen retrieval and fixation, antibodies backed by real IHC images, the tissue controls to run alongside, and protocols taken from published papers.
Open the ID3 IHC GuideFacts about DNA-binding protein inhibitor ID-3.
Involved in myogenesis by inhibiting skeletal muscle and cardiac myocyte differentiation and boosting muscle precursor cells proliferation. Inhibits the binding of E2A-containing protein complexes to muscle creatine kinase E-box enhancer.
