Recombinant human Neprilysin/CD10 protein

MME, also known as neprilysin, is a zinc metallopeptidase expressed at the cell surface of a variety of cells. It degrades the amyloid beta peptide whose abnormal misfolding and aggregation in neural tissue has been implicated as a cause of Alzheimer's disease. It is expressed in a wide variety of tissues and is particularly abundant in kidney. It is also a common acute lymphocytic leukemia antigen that is an important cell surface marker in the diagnosis of human acute lymphocytic leukemia (ALL) . It is of use in hematological diagnosis since it is expressed by early B, pro-B and pre-B lymphocytes, and by lymph node germinal centers. Recombinant human MME, fused to His-tag at C-terminus, was expressed in insect cell and purified by using conventional chromatography techniques.
