Product Overview
Clone 28G35 is a rabbit monoclonal antibody that recognizes glutamate--cysteine ligase regulatory subunit (gene GCLM) in human, mouse and rat samples and is validated for Western blot, IHC and immunoprecipitation. The predicted molecular weight is 30.7 kDa, and the supplier reports an observed band at about 28 kDa.
GCLM is the regulatory (modifier) subunit of glutamate–cysteine ligase, the rate-limiting enzyme of glutathione synthesis. It has no catalytic activity of its own but raises the efficiency of the catalytic subunit GCLC and lowers its sensitivity to feedback inhibition by glutathione. GCLM is an NRF2 target gene studied in oxidative stress.
