標靶描述

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.

外觀

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.

重構

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.

儲存和穩定性

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.
