Product Overview
This rabbit polyclonal antibody recognizes glutamate--cysteine ligase catalytic subunit (gene GCLC) in human, mouse and rat samples and is validated for flow cytometry, IHC and Western blot. The predicted molecular weight is 72.8 kDa, and the supplier reports an observed band at about 72 kDa.
GCLC is the catalytic subunit of glutamate–cysteine ligase, the enzyme that carries out the first and rate-limiting step of glutathione synthesis. Together with the modifier subunit GCLM, it joins glutamate and cysteine in an ATP-dependent reaction. GCLC is a classic NRF2 target gene and is studied in antioxidant defense and ferroptosis.
