Opis wartości docelowych

Tumor necrosis factor (UniProt: P01375; also known as Cachectin, TNF-alpha, Tumor necrosis factor ligand superfamily member 2, TNF-a) is encoded by the TNF (also known as TNFA, TNFSF2) gene (Gene ID: 7124) in human. TNF is a pro-inflammatory cytokine that is mainly produced by activated macrophages and natural killer (NK) cells. The uncleaved molecule has a cytoplasmic domain (aa 1-35), a transmembrane domain (aa 36-56), and an extracellular domain (aa 57-233). Following its synthesis, it is cleaved into 6 different chains: Tumor necrosis factor, membrane form (NTF); Intracellular domain 1 (ICD1; aa 1-39); Intracellular domain 2 (ICD2; aa 1-35); C-domain 1; C-domain 2; and Tumor necrosis factor, soluble form (aa 77-233). The soluble form is derived from the membrane form by proteolytic processing. During synthesis, TNF translocates to the cell membrane where the TNF-converting enzyme (TACE) releases the membrane-bound 26 kDa molecule into the extracellular milieu as a 17 kDa protein. Both membrane-bound and released TNF are active but depending on their location they perform different functions. TNF mediates its biological activities through binding to type I and II TNF receptors (TNFR1 and TNFRII). Transmembrane TNF exerts its biological function in a cell-to-cell contact fashion, which is distinct from the feature of soluble TNF that acts at sites remote from the TNF -producing cells. TNF is a potent pyrogen that causes fever by its direct action or by stimulation of interleukin-1 secretion . It has been implicated in the induction of cachexia. Under certain conditions it can stimulate cell proliferation and also induce cell differentiation. It is known to impair regulatory T-cells (Treg) function in subjects with rheumatoid arthritis via dephosphorylation of FOXP3. It up-regulates the expression of protein phosphatase 1 (PP1) that dephosphorylates the key Ser-418 residue of FOXP3 and inactivates it leading to defective Treg cell function. This ZooMAbZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Postać fizyczna

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.

Rekonstytucja

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.

Przechowywanie i stabilność

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.
