General description
Glutamate-cysteine ligase regulatory subunit (UniProt: P48507; GCS light chain, Gamma-ECS regulatory subunit, Gamma-glutamylcysteine synthetase regulatory subunit, Glutamate-cysteine ligase modifier subunit) is encoded by the GCLM (also known as GLCLR) gene (Gene ID: 2730) in human. Glutathione (GSH), an abundant cellular antioxidant, is maintained at millimolar concentrations in most cells. Although the GSH levels can vary as much as 10-fold between different cell types, the concentration of GSH in a given cell type is consistent, unless modified by cellular redox reactions. Glutamate cysteine ligase (GCL), which synthesizes -glutamyl-cysteine ( -GC), is the rate-limiting enzyme in GSH biosynthesis. GCL is a heterodimeric enzyme that is composed of a catalytic (GCLC) and a modifier (GCLM) subunit that are encoded by separate genes on different chromosomes. GCLC possesses the catalytic activity for -GC formation. GCLM interacts with GCLC, making the holoenzyme (GCLholo) that is kinetically more efficient in -GC synthesis. GCLM (-/-) knockout mice show significantly reduced levels of GSH compared the wild-type mice. In human, GCL deficiency is a rare autosomal recessive trait that compromises production of glutathione and subjects show markedly reduced levels of erythrocyte glutathione, leading to hemolytic anemia and, in some cases, impaired neurological function. Two isoforms of GCLM have been described that are produced by alternative splicing. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Biochem/physiol Actions
Clone 1D19 is a ZooMAb® Rabbit recombinant monoclonal antibody that specifically detects Glutamate-cysteine ligase regulatory subunit (GCLM).
Physical form
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.
Preparation Note
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.
