GCLC Antibody / Glutathione Biosynthesis Antibody (FY13385)

GCLC Antibody Liver Cancer IF. Immunofluorescent staining of FFPE human liver carcinoma tissue using GCLC Antibody / Glutathione Biosynthesis Antibody demonstrates widespread cytoplasmic red fluorescence throughout neoplastic hepatic cell populations. The staining pattern is consistent with expression of Glutamate-Cysteine Ligase Catalytic Subunit (GCLC), the rate-limiting enzyme in glutathione biosynthesis and a key regulator of cellular antioxidant defense pathways. Robust cytoplasmic immunoreactivity highlights the high metabolic and redox demands of tumor-associated cells and is consistent with the established role of GCLC in glutathione production, oxidative stress responses, and cellular detoxification mechanisms. Nuclei are visualized with DAPI counterstain (blue). The observed staining demonstrates the utility of this antibody for studies of glutathione metabolism, redox biology, oxidative stress regulation, cancer metabolism, and antioxidant defense pathways. HIER: EDTA buffer, pH 8.0.

GCLC Antibody Multi-Species WB. Western blot analysis using GCLC Antibody / Glutathione Biosynthesis Antibody demonstrates strong immunoreactive bands at approximately 73 kDa in human HeLa, Jurkat, and HepG2 cell lysates, as well as rat brain, rat C6, and mouse brain samples. The observed molecular weight is consistent with the predicted size of Glutamate-Cysteine Ligase Catalytic Subunit (GCLC), the catalytic component of the rate-limiting enzyme in glutathione biosynthesis. Consistent detection across human, rat, and mouse samples supports recognition of a conserved GCLC epitope and demonstrates broad species reactivity. Additional lower molecular weight bands observed in selected samples are consistent with previously reported truncated or proteolytically processed forms of GCLC. The observed immunoreactivity demonstrates the utility of this antibody for studies of glutathione metabolism, oxidative stress responses, antioxidant defense pathways, cellular detoxification, and redox regulation.

GCLC Antibody Colon Cancer IHC. Immunohistochemical staining of FFPE human colon carcinoma tissue using GCLC Antibody / Glutathione Biosynthesis Antibody demonstrates moderate to strong cytoplasmic HRP-DAB brown staining throughout malignant glandular epithelial cell populations. The staining pattern is consistent with expression of Glutamate-Cysteine Ligase Catalytic Subunit (GCLC), the catalytic component of the rate-limiting enzyme in glutathione biosynthesis and a key regulator of cellular antioxidant defense mechanisms. Prominent immunoreactivity within neoplastic epithelial structures is consistent with the established role of GCLC in glutathione production, oxidative stress adaptation, detoxification pathways, and metabolic homeostasis. The observed staining demonstrates the utility of this antibody for studies of redox biology, antioxidant defense, cancer metabolism, oxidative stress signaling, and glutathione-dependent cellular protection mechanisms. HIER: EDTA buffer, pH 8.0.

GCLC Antibody A549 FACS. Flow cytometry analysis of permeabilized human A549 cells stained with GCLC Antibody / Glutathione Biosynthesis Antibody demonstrates a pronounced rightward shift of the GCLC-stained population (blue) relative to both the isotype control (green) and unstained control (red). The observed fluorescence shift is consistent with intracellular expression of Glutamate-Cysteine Ligase Catalytic Subunit (GCLC), the catalytic component of the rate-limiting enzyme in glutathione biosynthesis.
