This assay has high sensitivity and excellent specificity for detection of Tumor Necrosis Factor Ligand Superfamily, Member 4 (TNFSF4). No significant cross-reactivity or interference between Tumor Necrosis Factor Ligand Superfamily, Member 4 (TNFSF4) and analogues was observed.

For unopened kit: All the reagents should be kept according to the labels on vials. The Standard, Detection Reagent A, Detection Reagent B and the 96-well strip plate should be stored at -20 degree C upon receipt while the others should be at 4 degree C. For opened kit: When the kit is opened, the remaining reagents still need to be stored according to the above storage condition. Besides, please return the unused wells to the foil pouch containing the desiccant pack, and reseal along entire edge of zip-seal. The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition. To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.

Samples: Serum, plasma, tissue homogenates and other biological fluids. Assay Type: Sandwich. Detection Range: 15.63-1000pg/mL. Sensitivity: Typically less than 6.2pg/mL.

Precision: Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Tumor Necrosis Factor Ligand Superfamily, Member 4 (TNFSF4) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Tumor Necrosis Factor Ligand Superfamily, Member 4 (TNFSF4) were tested on 3 different plates, 8 replicates in each plate. CV(%) = SD/meanX100 . Intra-Assay: CV<10% . Inter-Assay: CV<12% . Assay Procedure Summary: 1. Prepare all reagents, samples and standards;. 2. Add 100uL standard or sample to each well. Incubate 2 hours at 37 degree C;. 3. Aspirate and add 100uL prepared Detection Reagent A. Incubate 1 hour at 37 degree C;. 4. Aspirate and wash 3 times;. 5. Add 100uL prepared Detection Reagent B. Incubate 30 minutes at 37 degree C;. 6. Aspirate and wash 5 times;. 7. Add 90uL Substrate Solution. Incubate 15-25 minutes at 37 degree C;. 8. Add 50uL Stop Solution. Read at 450nm immediately.

Principle of the Assay: The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Tumor Necrosis Factor Ligand Superfamily, Member 4 (TNFSF4). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Tumor Necrosis Factor Ligand Superfamily, Member 4 (TNFSF4). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Tumor Necrosis Factor Ligand Superfamily, Member 4 (TNFSF4), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm 10nm. The concentration of Tumor Necrosis Factor Ligand Superfamily, Member 4 (TNFSF4) in the samples is then determined by comparing the O.D. of the samples to the standard curve.

This gene encodes a cytokine of the tumor necrosis factor (TNF) ligand family. The encoded protein functions in T cell antigen-presenting cell (APC) interactions and mediates adhesion of activated T cells to endothelial cells. Polymorphisms in this gene have been associated with Sjogren's syndrome and systemic lupus erythematosus. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2014]

TNFSF4: Cytokine that binds to TNFRSF4. Co-stimulates T-cell proliferation and cytokine production. Genetic variations in TNFSF4 influence susceptibility to systemic lupus erythematosus (SLE). SLE is a chronic, inflammatory and often febrile multisystemic disorder of connective tissue. It affects principally the skin, joints, kidneys and serosal membranes. It is thought to represent a failure of the regulatory mechanisms of the autoimmune system. The upstream region of TNFSF4 contains a single risk haplotype for SLE, which is correlated with increased expression of both cell-surface TNFSF4 and TNFSF4 transcripts. Increased levels of TNFSF4 are thought to augment T-cell-APC interaction and the functional consequences of T-cell activation, thereby destabilizing peripheral tolerance. Belongs to the tumor necrosis factor family. Protein type: Cytokine; Membrane protein, integral; Cell cycle regulation. Chromosomal Location of Human Ortholog: 1q25.
