Recombinant Human TNF-β/TNFSF1

Name

Recombinant Human TNF-β/TNFSF1 (Recombinant Human Tumor Necrosis Factor-β/TNFSF1; rHuTNF-β/TNFSF1)；重组人肿瘤坏死因子β/TNFS1

Synonyms

LTA; Lymphotoxin alpha; tnfb; TNF-beta; TNFSF1; TNFSF1B; LT; LT-alpha; lymphotoxin alpha (TNF superfamily, member 1); TNFBlymphotoxin-alpha; TNFSF1TNF-beta; tumor necrosis factor beta; Tumor necrosis factor ligand superfamily member 1

Purity

>96% by SDS-PAGE and HPLC analyses.

Biological Activity

Fully biologically active when compared to standard. The ED50 as determined by a cytotoxicity assay using murine L929 cells is less than 5pg/ml, corresponding to a specific activity of >2.0×10⁸IU/mg in the presence of actinomycin D.

Physical Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Formulation

Lyophilized from a 0.2μm filtered concentrated solution in PBS, pH7.4, with 0.02% Tween-20.

Endotoxin

Less than 0.1EU/μg of rHuTNF-β/TNFSF1 as determined by LAL method.

Reconstitution

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0mg/ml. Stock solutions should be apportioned into working aliquots and stored at ≤-20℃. Further dilutions should be made in appropriate buffered solutions.

Background

TNF-beta, also known as lymphotoxin-alpha (LTalpha) and TNF-alpha are two structurally and functionally related proteins that bind to the same cell surface receptors (TNF RI and TNF RII) and produce a vast range of similar, but not identical effects. Mature TNF-beta/LTalpha and TNF-alpha share approximately 35% protein sequence homology, and the biologically active secreted forms of both proteins are trimers. Human and mouse TNF-beta/LTalpha share approximately 74% homology in their amino acid sequence and exhibit cross-species activity. Soluble TNF-beta/LTalpha is a homotrimer in solution. Secreted TNFbeta/LTalpha also complexes with the membrane associated LTbeta/TNFSF3 to generate two types of heterotrimers, LTalpha1/beta2 and LTalpha2/beta1.
