Description générale

ZooMAb® antibodies represent an entirely new generation of recombinant monoclonal antibodies. Each ZooMAb® antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb® antibodies are reliably available and ready to ship when you need them.

Spécificité

Clone 1G5 is a ZooMAb® recombinant rabbit monoclonal antibody that specifically detects GPx4. It targets an epitope within 22 amino acids from the C-terminal region.

Immunogène

KLH-conjugated linear peptide corresponding to 22 amino acids from the C-terminal region of human GPX4.

Application

Quality Control Testing

Evaluated by Western Blotting in U-937 cell lysate.

Western Blotting Analysis (WB): A 1:1,000 dilution of this antibody detected GPx4 in U-937 cell lysate.

Tested Applications

Western Blotting Analysis: A 1:1,000-10,000 dilution from a representative lot detected GPx4 in lysate from mouse liver and rat testis tissue.

Immunohistochemistry (Paraffin) Analysis: A 1:1,000 dilution from a representative lot detected GPx4 in human testis tissue sections.

Affinity Binding Assay: A representative lot of this antibody bound GPx4 peptide with at least ten thousand-fold (10,000X) higher than with non-specific control peptide.

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user.

Description de la cible

Phospholipid hydroperoxide glutathione peroxidase, cytosolic (UniProt: P36969; also known as PHGPx, Glutathione peroxidase 4, GPx-4, GSHPx-4) is encoded by the GPX4 gene (Gene ID: 2879) in human. The protein encoded by this gene belongs to the glutathione peroxidase family, members of which catalyze the reduction of hydrogen peroxide, organic hydroperoxides and lipid hydroperoxides, and thereby protect cells against oxidative damage. This isozyme is also a selenoprotein, containing the rare amino acid selenocysteine (Sec) at its active site. This selenocysteine is crucial for the enzyme′s catalytic activity. Sec is encoded by the UGA codon, which normally signals translation termination. Three functionally distinct isozymes of GPx4 have been described and are known as mGPx4 (mitochondrial), cGPx4 (cytosolic), and nGPx4 (nuclear). They originate from a single GPX4 gene. The cytosolic isoform is ubiquitously expressed at moderate levels in most mammalian cells. On the other hand, mitochondrial and nuclear isoforms are overexpressed in spermatoid cells. GPx4 is a considered to be a ′moonlighting′ protein because of its ability to serve dual functions as a peroxidase, that has been implicated in anti-oxidative defense, gene expression regulation, and programmed cell death, and as a structural protein in spermatogenesis. Mutations or deficiencies in GPX4 are associated with several diseases. One of the most severe conditions linked to GPX4 deficiency is Sedaghatian-type spondylometaphyseal dysplasia (SMDS), a rare genetic disorder characterized by skeletal abnormalities, neurological impairment, and early infant death. Homozygous GPx4-deficient mice are reported to die utero before E7.5. Similarly, homozygous mice expressing catalytically inactive GPx4 variants (Sec46Ala/Ser mutant) do not survive beyond the 7th day of embryogenesis. This ZooMAb® recombinant monoclonal antibody, generated by our proprietary technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals. (Ref.: Borchert, A., et al (2010). Immunol. Lett. 133 (2); 85-93).

Forme physique

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.

Reconstitution

300 µg/mL after reconstitution at 25 µL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Stockage et stabilité

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.
