Glutamate-cysteine ligase catalytic subunit (UniProt: P48506; EC:6.3.2.2; also known as GCS heavy chain, Gamma-ECS, Gamma-glutamylcysteine synthetase) is encoded by the GCLC (also known as GLCL, GLCLC) gene (Gene ID: 2729) in human. The glutamate-cysteine ligase catalytic subunit (GCLC) is part of the glutamate-cysteine ligase (GCL) enzyme, which also includes a modifier subunit (GCLM). GCLC contains the active site of the enzyme and is primarily responsible for its enzymatic activity. Structurally, GCLC features several domains critical for substrate binding and catalysis, and it functions optimally when associated with GCLM, which enhances the enzyme′s activity and stability. GCLC is crucial for the synthesis of glutathione, a major antioxidant in cells. It catalyzes the first and rate-limiting step of glutathione synthesis, which involves the formation of gamma-glutamylcysteine from glutamate and cysteine. This process is vital for maintaining cellular redox homeostasis, detoxifying harmful substances, and modulating cell signaling and proliferation. GCLC is expressed ubiquitously across various tissues, with higher levels observed in organs that are involved in detoxification processes, such as the liver and kidneys. Its expression can be upregulated in response to oxidative stress, toxins, and other factors that increase the cellular demand for glutathione. Decreased GCLC activity can lead to reduced glutathione levels, contributing to oxidative stress and cellular damage. This mechanism is relevant in various pathologies, including neurodegenerative diseases like Alzheimer′s and Parkinson′s disease, where oxidative stress is a significant contributing factor. Additionally, GCLC dysregulation has been implicated in cancer, cardiovascular diseases, and conditions like diabetes, where impaired antioxidant defenses exacerbate disease progression.

KLH-conjugated linear peptide corresponding to 24 amino acids from the N-terminal half of human GCLC.

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 µL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.

Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.
