Descripción de destino

Signal transducer and activator of transcription 3 (UniProt: P40763; also known as Stat3, Acute-phase response factor) is encoded by the STAT3 (also known as APRF) gene (Gene ID: 6774) in human. STAT3 is expressed in most cell types and is predominantly cytoplasmic in its latent form. It serves as a cytoplasmic transcription factor that has a dual function of signal transduction and activation of transcription. It is activated by multiple cytokines, growth factors, and leptin. Stat3 is shown to shuttle between the nucleus and the cytoplasm. It is activated by phosphorylation at Tyrosine 705, which induces dimerization, nuclear translocation, and DNA binding. A motif comprising of amino acids 150-162 is essential for its nuclear import. In the nucleus it recruits coactivators, such as NCOA1 or MED1, to the promoter region of the target genes. It binds to DNA as either a homodimer or as a heterodimer with Stat1. Stat3 regulates inflammatory response by regulating differentiation of naive CD4+ T-cells into T-helper Th17 or regulatory T-cells. It may also play an anti-apoptotic role by transactivating BIRC5 expression under leptin activation. Cytoplasmic Stat3 is shown to repress macroautophagy by inhibiting EIF2AK2/PKR activity. Stat3 is also involved in cell cycle regulation by inducing the expression of key genes that are involved in the progression from G1 to S phase. Constitutively activated Stat3 is reported in a number of human cancers. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Forma física

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.

Reconstitución

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.

Almacenamiento y estabilidad

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.
