Histone H2A.X, phosphorylated (Ser139) (H2A histone family member X, H2A.FX, H2A/X, H2AFX)

May be stored at 4 °C for short-term only. For long-term storage, store at -20 °C. Aliquots are stable for at least 12 months at -20 °C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.

Recognizes human Histone H2A.X phosphorylated at Ser139, Mr 15kD. A broad species crossreactivity is expected based on conservation of sequence homology.
