Human TNF RII/TNFRSF1B Antibody Summary

Species Reactivity

Human

Specificity

Detects human TNF RII/TNFRSF1B in direct ELISAs and Western blots. In direct ELISAs, less than 50% cross‑reactivity with recombinant mouse TNF RII is observed and less than 5% cross-reactivity with recombinant rat TNF RII is observed.

Source

Polyclonal Goat IgG

Purification

Antigen Affinity-purified

Immunogen

E. coli-derived recombinant human TNF RII/TNFRSF1B

Formulation

Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.

Endotoxin Level

<0.10 EU per 1 μg of the antibody by the LAL method.

Label

Unconjugated

Applications

Recommended Concentration

Sample

Western Blot

0.1 µg/mL

Recombinant Human TNF RII/TNFRSF1B

Flow Cytometry

2.5 µg/10⁶ cells

Human peripheral blood granulocytes

CyTOF-ready

Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.

Knockout Validated

TNF RII/TNFRSF1B was detected in immersion fixed THP‑1 human acute monocytic leukemia cell line but is not detected in TNF RII/TNFRSF1B knockout (KO) THP‑1 human cell line.

Neutralization

Measured by its ability to neutralize TNF RII/TNFRSF1B-mediated inhibition of cytotoxicity in the L‑929 mouse fibroblast cell line. The Neutralization Dose (ND₅₀) is typically 0.04-0.2 µg/mL in the presence of 0.075 µg/mL Recombinant Human TNF RII/TNFRSF1B Fc Chimera, 0.25 ng/mL Recombinant Human TNF‑ alpha, and 1 µg/mL actinomycin D.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

TNF RII/TNFRSF1B Specificity is Shown by Immunocytochemistry in Knockout Cell Line. TNF RII/TNFRSF1B was detected in immersion fixed THP‑1 human acute monocytic leukemia cell line but is not detected in TNF RII/TNFRSF1B knockout (KO) THP‑1 human cell line using Goat Anti-Human TNF RII/TNFRSF1B Antigen Affinity-purified Polyclonal Antibody (Catalog # AF726) at 5 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; NL001) and counterstained with DAPI (blue). Specific staining was localized to cell membrane. Staining was performed using our protocol for Fluorescent ICC Staining of Non-adherent Cells.

TNF RII/TNFRSF1B Inhibition of TNF‑ alpha -induced Cytotoxicity and Neutralization by Human TNF RII/TNFRSF1B Antibody. Recombinant Human TNF RII/TNFRSF1B Fc Chimera (726-R2) inhibits Recombinant Human TNF-a (210-TA) induced cytotoxicity in the L-929 mouse fibroblast cell line in a dose-dependent manner (orange line), as measured by Resazurin (AR002). Inhibition of Recombinant Human TNF-a (0.25 ng/mL) activity elicited by Recombinant Human TNF RII/TNFRSF1B Fc Chimera (0.075 µg/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human TNF RII/TNFRSF1B Antigen Affinity-purified Polyclonal Antibody (Catalog # AF726). The ND₅₀ is typically 0.04-0.2 µg/mL in the presence of the metabolic inhibitor actinomycin D (1 µg/mL).

Background: TNF RII/TNFRSF1B

TNF RII, also known as p75 or p80 TNF R, is a prototypic member of the TNF receptor superfamily and has been designated TNFRSF1B. It binds TNF with high affinity and is expressed primarily in cells of the immune system.
