Product Summary for Mouse/Rat TNF RII/TNFRSF1B Quantikine ELISA Kit
The Quantikine Mouse/Rat TNF RII Immunoassay is a 4.5 hour solid phase ELISA designed to measure mouse or rat TNF RII in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant mouse TNF RII and antibodies raised against the recombinant factor. This immunoassay has been shown to quantitate the recombinant protein accurately. Results obtained using natural mouse or rat TNF RII showed linear curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for natural mouse or rat TNF RII.

Recovery for Mouse/Rat TNF RII/TNFRSF1B Quantikine ELISA Kit
The recovery of TNF RII spiked to levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Mouse Cell Culture Supernates (n=5) | 102 | 83-119 |
| Mouse EDTA Plasma (n=5) | 95 | 80-119 |
| Mouse Serum (n=5) | 99 | 91-105 |
| Rat Cell Culture Supernates (n=5) | 98 | 85-116 |

| Rat Serum (n=5) | 97 | 84-114 |
Linearity
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of TNF RII were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.

Background: TNF RII/TNFRSF1B
TNF RII (Tumor Necrosis Factor Receptor II), also known as TNFRSF1B, p75/p80, and CD120b, is a widely expressed receptor for membrane-associated TNF-alpha and Lymphotoxin-alpha. Its activation initiates pro-inflammatory and pro-survival responses via NFkB-dependent signaling pathways, although it may also induce apoptosis.
Long Name
Tumor Necrosis Factor Receptor II
Alternate Names
CD120b, TNFRII, TNFRSF1B
Gene Symbol
TNFRSF1B
