Target description

Interferon regulatory factor 1 (UniProt: P10914; also known as IRF-1) is encoded by the IRF1 gene (Gene ID: 3659) in human. IRF-1 is a transcriptional regulator that is expressed constitutively in all cell types except in early embryonal cells. It can exist as a monomer and as a homodimer and displays remarkable functional diversity in the regulation of cellular responses, including the regulation of interferon (IFN) and IFN-inducible genes and host response to viral and bacterial infections. It also regulates many genes expressed during hematopoiesis, inflammation, immune responses, cell proliferation and differentiation, and growth arrest and apoptotic cell death following DNA damage. It is reported to act as a tumor suppressor and plays a role blocking tumor cell growth and stimulating an immune response against tumor cells. It is known to represses genes involved in anti-proliferative response, such as survivin, cyclin B1, cyclin E1, Cdk1, Cdk2, Cdk4 and in immune response, such as FOXP3, IL-4, and TLR4. IRF-1 is reported to stimulate p53/TP53-dependent transcription through enhanced recruitment of EP300 leading to increased acetylation of p53/TP53. Its DNA-binging domains are located in the first 115 amino acids of N-terminal region and contains a series of five well-conserved tryptophan-rich repeats. IRF-1 can be phosphorylated by casein kinase 2, which positively regulates its activity. Mutations in IRF1 gene have been linked to increased susceptibility to gastric cancer that can spread to esophagus and small intestine. This ZooMAbZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 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.

Storage and Stability

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.
