Jumonji Domain containing 2A (JMJD2A) is a lysine specific demethylase with emerging roles in histone modification or epigenetic remodeling. This JMJD2A polyclonal antibody was raised against an N-terminal recombinant fragment of JMJD2A. This fragment includes amino acids 1-350 including the JMJN and JMJC domains but not the two LAP/PHD zinc finger or Tudor domains of the 1,064 amino acid protein. JMJD2A is detected at 135 kDa by western blotting using a DLD1 cell lysate as a positive control. Also, the expression of JMJD2A varies by tissue, and northern blotting sμggests skeletal muscle as a negative control and lung as a positive control tissue.
