Description de la cible

Signal transducer and activator of transcription 2 (UniProt: P52630; also known as STAT2, p113) is encoded by the STAT2 gene (Gene ID: 6773) in human. The JAK-STAT signaling pathway play an important role in cell proliferation, cell differentiation, cell migration, and cell death. It is the principal signaling mechanism for a variety of cytokines and growth factors. In mammals, seven different STATs have been recognized. They contain a conserved tyrosine residue near the C-terminus, which is phosphorylated by JAKs, which allows the dimerization of STATs by interacting with a conserved SH2 domain. In their latent form STATs are located in the cytoplasm and upon phosphorylation they are transported into the nucleus by an importin -5 dependent mechanism. In the nucleus, dimerized STATs bind to specific regulatory sequences to activate or repress transcription of target genes. The main function of STAT2 is to mediate IFN- /β signaling. Following type I interferon binding to cell surface receptors, JAK kinases are activated, leading to tyrosine phosphorylation of STAT1 and STAT2. The phosphorylated STATs dimerize, associate with IRF9/ISGF3G to form a complex termed ISGF3 transcription factor, that enters the nucleus. ISGF3 binds to the IFN stimulated response element (ISRE) to activate the transcription of interferon stimulated genes. STAT2 is also reported to serve as a regulator of mitochondrial fission by modulating the phosphorylation of DNM1L at serine 616 and serine 637, which activate and inactivate the GTPase activity of DNM1L respectively. Two isoforms of STAT2 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.

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.
