Plate: Pre-coated

Protocol: human sTNFsRII ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for sTNFsRII has been precoated onto 96-well plates. Standards(NSO, L23-D257) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for sTNFsRII is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the human sTNFsRII amount of sample captured in plate.

Assay Procedure:

Aliquot 0.1 mL per well of the 500pg/mL, 250pg/mL, 125pg/mL, 62.5pg/mL, 31.3pg/mL, 15.6pg/mL, 7.8pg/mL human sTNFsRII standard solutions into the precoated 96-well plate. Add 0.1 mL of the sample diluent buffer into the control well (Zero well). Add 0.1 mL of each properly diluted sample of human cell culture supernates, serum, plasma( heparin, EDTA, citrate) or urine to each empty well. See "Sample Dilution Guideline" above for details. We recommend that each human sTNFsRII standard solution and each sample is measured in duplicate.

Assay Precision:

• Sample 1: n=16, Mean(pg/ml): 63, Standard deviation: 3.09, CV(%): 4.9
• Sample 2: n=16, Mean(pg/ml): 125, Standard deviation: 7.13, CV(%): 5.7
• Sample 3: n=16, Mean(pg/ml): 257, Standard deviation: 9.25, CV(%): 3.6,
• Sample 1: n=24, Mean(pg/ml): 78, Standard deviation: 4.76, CV(%): 6.1
• Sample 2: n=24, Mean(pg/ml): 134, Standard deviation: 9.65, CV(%): 7.2

Background:

Protein Function: Receptor with high affinity for TNFSF2/TNF-alpha and approximately 5-fold lower affinity for homotrimeric TNFSF1/lymphotoxin-alpha. The TRAF1/TRAF2 complex recruits the apoptotic suppressors BIRC2 and BIRC3 to TNFRSF1B/TNFR2. This receptor mediates most of the metabolic effects of TNF-alpha. Isoform 2 blocks TNF-alpha-induced apoptosis, which suggests that it regulates TNF-alpha function by antagonizing its biological activity. .

Background: Tumor necrosis factor receptor p75(TNF-R p75, or TNF-R2) is a 75- kDa type I transmembrane protein expressed predominantly on cells of hematopoietic lineage. TNF-R p75 belongs to the TNF receptor superfamily characterized by cysteine-rich extracellular regions composed of three to six disulfide-linked domains. The tumor necrosis factor receptor II(TNFRII) gene localizes to 1p36. 2, a genomic region characteristically deleted in neuroblastomas and other malignancies. In addition, TNFRII is the principal mediator of the effects of TNF on cellular immunity, and it may cooperate with TNFRI in the killing of nonlymphoid cells. The standard product used in this kit is recombinant human sTNFRII, consisting of 24-206 amino acid sequence with the molecular mass of 20KDa.
