Product Overview
This rabbit polyclonal antibody targets GMP synthase (gene GMPS) in human, mouse and rat samples and is validated for Western blot, flow cytometry and ELISA. The predicted molecular weight is 76.7 kDa, and the supplier reports an observed band at about 77 kDa.
GMP synthase (GMPS) catalyzes the final step of de novo guanine nucleotide synthesis, converting XMP to GMP using glutamine and ATP. Because it supplies guanine nucleotides for DNA and RNA, it is studied in nucleotide metabolism and cell proliferation.

Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places GMP synthase in the cytoplasm. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
