Arginase 1 Antibody ARG1/6790R / Recombinant Rabbit Monoclonal [clone ARG1/6790R] (V8793)

Arginase 1 Antibody ARG1/6790R by WB in Human and Multiple Animal Species. Western blot analysis of human, mouse, rat, hamster, and guinea pig liver tissue lysates using Arginase 1 Antibody ARG1/6790R, a recombinant rabbit monoclonal antibody. Lane 1: human liver; lane 2: mouse liver; lane 3: rat liver; lane 4: hamster liver; lane 5: guinea pig liver. A prominent immunoreactive band is detected at approximately 35-38 kDa in human liver, consistent with the predicted molecular weight of ARG1 (~35 kDa). No corresponding bands are visible in the four animal liver lysates under the conditions tested, indicating human-selective recognition by this antibody in this experiment.

Western blot analysis of human liver tissue lysate using Arginase 1 Antibody ARG1/6790R. Predicted molecular weight ~35 kDa.

Arginase 1 Antibody ARG1/6790R by IHC in Human Hepatocellular Carcinoma. Immunohistochemistry of FFPE human hepatocellular carcinoma tissue using Arginase 1 Antibody ARG1/6790R, a recombinant rabbit monoclonal antibody. Strong, diffuse brown DAB staining is observed predominantly in the cytoplasm of tumor cells, with occasional nuclear staining and variable cytoplasmic intensity. The staining pattern is consistent with ARG1 expression in hepatocellular carcinoma and its role as a marker of hepatocellular differentiation. Nuclei are counterstained blue with hematoxylin. The lower-left inset shows a secondary-only negative control, with PBS substituted for the primary antibody, demonstrating minimal background staining.
