Product Information

Product Usage Information

Application Dilution
Flow Cytometry (Live) 1:50

Storage

Supplied in PBS (pH 7.2), less than 0.1% sodium azide, and 2 mg/mL BSA. Store at 4°C. Do not aliquot the antibody. Protect from light. Do not freeze.

Specificity / Sensitivity

TNF-R2 (E8D7P) Rabbit mAb (Alexa Fluor® 488 Conjugate) recognizes endogenous levels of total TNF-R2 protein. This antibody cross-reacts with an unidentified protein of 180 kDa in some cell extracts.

Species Reactivity:

Human

Source / Purification

Monoclonal antibody is produced by immunizing animals with recombinant protein specific to the amino terminus of human TNF-R2 protein.

Product Description

This Cell Signaling Technology® antibody is conjugated to Alexa Fluor® 488 fluorescent dye under optimal conditions and tested in-house for direct flow cytometric analysis in human cells. This antibody conjugate is expected to exhibit the same species cross-reactivity as the unconjugated TNF-R2 (E8D7P) Rabbit mAb #72337.

Background

TNF-α is an important cytokine produced by numerous cell types, including neutrophils, activated lymphocytes, macrophages, and NK cells. It plays a critical role in inflammatory responses and apoptosis (1). TNF-α exists as a membrane-anchored and soluble form, both of which show biological activity. Response to TNF-α is mediated through two receptors, TNF-R1, which is widely expressed, and TNF-R2, which is expressed mainly in immune and endothelial cells (2). Antagonists to TNF-α have been validated as therapeutic targets for rheumatoid arthritis and other immune disorders (3).

The two receptors for TNF-α, TNF-R1 (55 kDa) and TNF-R2 (75 kDa), can mediate distinct cellular responses (4,5). In most cases, cytotoxicity elicited by TNF has been reported to act through TNF-R1 (6,7). In contrast, TNF-R2 appears to be important in T cell signaling and responses to infection (7,8). TNF-R2 binds to distinct members of the TRAF family, leading to the activation of NF-κB (9,10). Soluble forms of both receptors have also been characterized which can bind TNF-α and may play an important role in immune disorders (11,12).
