Data Example
Intracellular Staining by Flow Cytometry
Detection of TNF‑ beta /TNFSF1 in HuT 78 Human Cell Line by Flow Cytometry. HuT 78 human cutaneous T cell lymphoma cell line was stained with Mouse Anti-Human TNF‑ beta /TNFSF1 Fluorescein-conjugated Monoclonal Antibody (Catalog # IC2111F, filled histogram) or isotype control antibody (Catalog # IC002F, open histogram). To facilitate intracellular staining, cells were fixed with Flow Cytometry Fixation Buffer (Catalog # FC004) and permeabilized with Flow Cytometry Permeabilization/Wash Buffer I (Catalog # FC005).

Background: Lymphotoxin-alpha/TNF-beta

Tumor necrosis factor beta (TNF-beta ), also known as lymphotoxin-alpha (LT-alpha ), 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. Among these effects is the ability to kill certain tumor cells directly, from which the names tumor necrosis factor and lymphotoxin both derive. Mature TNF-beta /LT-alpha and TNF-alpha share approximately 35% protein sequence homology and the biologically active secreted forms of both proteins are homotrimers. Whereas TNF-alpha can exist as a type II membrane protein, TNF-beta /LT-alpha possesses a typical signal peptide sequence and is a secreted protein. It has been shown that TNF-beta /LT-alpha is also present on the cell surface of activated T, B and LAK cells as a heteromeric complex with LT-beta, a type II membrane protein that is another member of the TNF ligand family. The genes for TNF-alpha, TNF-beta /LT-alpha, and LT-beta are closely linked within the major histocompatibility complex.

TNF-beta /LT-alpha is expressed in activated T- and B-lymphocytes. In addition to its cytotoxic action on tumor cells, TNF-beta /LT-alpha has been shown to be a mediator of inflammation and immune function. Evidence is also accumulating that TNF-beta /LT-alpha and TNF-alpha are mediators in the pathogenesis of certain autoimmune diseases. TNF-beta /LT-alpha has also been shown to have a role in lymphoid organ development. Human and mouse TNF-beta /LT-alpha share approximately 74% homology in their amino acid sequence and exhibit cross-species activity.
