Product Overview
This rabbit polyclonal antibody recognizes histone-lysine N-methyltransferase MECOM in human samples and is validated for Western blot, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 138.1 kDa, and the supplier reports an observed band at about 138 kDa.
MECOM (also called EVI1) is a zinc finger transcription factor encoded at a locus that also produces the longer MDS1-EVI1 isoform, which carries a PR/SET domain. It is essential for maintaining hematopoietic stem cells. Overexpression of EVI1, often through 3q26 rearrangements, marks aggressive myeloid leukemia, and MECOM is studied in hematopoiesis and cancer.

Immunogen
Recombinant human EVI1/MECOM fragment (Glu125–Asp743), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human. UniProt places histone-lysine N-methyltransferase MECOM in the nucleus, nucleus speckle and cytoplasm. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
