Cat no: 029491

H2AFX, Phosphorylated (Ser139) (Histone H2A.x, H2a/x, H2AX)

As a member of the histone H2A family, histone H2A.x (H2A.x) is a variant histone H2A which replaces conventional H2A in a subset of nucleosomes. H2A.x is involved in the DNA repair of double-strand breakage (DSB) damage on nuclear DNA. After a double strand DNA break, H2A.x is rapidly phosphorylated at serine 139 by ATM kinase and becomes gamma-H2AFX. This phosphorylation step can extend up to several thousand nucleosomes from the actual site of the DSB and may mark the surrounding chromatin for recruitment of proteins required for DNA damage signaling and repair. As a part of posttranslational modifications during apoptosis caused by severe DNA damage, high expression of phosphorylated H2A.x is considered as an accurate indicator of apoptosis.\n\nApplications:\nSuitable for use in Western Blot, Immunohistochemistry and Immunocytochemistry. Other applications not tested.\n\nRecommended Dilution:\nWestern Blot: 1:1000-10,000\nImmunocytochemistry: 1:50-1:100\nImmunohistochemistry: 1:50-1:100\nOptimal dilutions to be determined by the researcher.\n\nPositive Control:\nEtoposide untreated and treated Jurkat cell lysates\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
