XAF-1 binds to XIAP, an inhibitor of caspases-3, -7, and -9, and triggers its relocation from the cytosol to the nucleus. Overexpression of XAF-1 results in the neutralization of XIAPs ability to inhibit cell death. XAF-1 is normally expressed in all adult and fetal tissues but was found to be present in very low levels in a variety of cancer cell lines. In contrast, XIAP levels have been shown to be high in a majority of cell lines. Low XAF-1 and high basal expression of XIAP may therefore play a critical role in maintaining survival of cancer cell lines. Both IFN-alpha2 and IFN-beta can induce XAF-1 mRNA in all cells examined but induction of XAF-1 protein (as observed by immunoblot analysis) was seen only in cell lines sensitive to the apoptotic effects of IFNs. Applications: Suitable for use in Immunohistochemistry, ELISA, Immunofluorescence and Western Blot. Other applications have not been tested. Recommended Dilutions: Immunohistochemistry: 2ug/ml Western Blot: 0.5-2ug/ml Immunofluorescence: 10ug/ml Optimal dilutions to be determined by the researcher.
