Arginase-1/ARG1 Protein, Human (C-His)

Arginase-1 Protein, Human (C-His) expresses in E. coli with a His tag at the C-terminus. Arginase-1 Protein inhibits the growth of the arginine-depleting enzyme arginine deiminase (ADI)-resistant Hep3B tumor cells in mice^[1].

Recombinant Human Arginase-1 has IC₅₀s of 0.18 U/ml and 0.07 U/ml for HepG2 and Hep3B cells. Recombinant Human Arginase-1 has a K_m value of 1.9 mM for arginine^[1].

The enzyme activity of this recombinant protein is testing in progress, we cannot offer a guarantee yet.
