Product Summary

The Quantikine Human LIGHT Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human LIGHT in cell culture supernates, serum, plasma, and saliva. It contains NS0-expressed recombinant human LIGHT and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human LIGHT 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 naturally occurring human LIGHT.

Precision

Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision

Cell Culture Media (n=4) 105 100-113
EDTA Plasma (n=5) 106 91-114
Heparin Plasma (n=5) 101 89-115
Serum (n=5) 102 85-114

Linearity

To assess the linearity of the assay, samples containing and/or spiked with high concentrations of LIGHT were serially diluted with the appropriate Calibrator Diluent to produce samples with values within the dynamic range of the assay.

Background: LIGHT/TNFSF14

LIGHT, also known as TNFSF14, is a homotrimeric glycoprotein in the TNF superfamily. It is expressed on the surface of activated lymphocytes, NK cells, immature dendritic cells, monocytes, and granulocytes. A soluble form can be shed by proteolysis. LIGHT binds and activates HVEM/TNFRSF14 to costimulate Th1 immune responses, enhance CD8+ T cell mediated tumor immunity, and regulate allogeneic T cell activation and allograft rejection. In addition, it binds and activates Lymphotoxin beta R/TNFRSF3 to induce apoptosis, cytokine production, mesenteric lymph node organogenesis, and maintenance of lymph node structure and function. It can also bind the soluble human decoy receptor DcR3/TNFRSF6B.

Assay Procedure

Refer to the product for complete assay procedure.

Bring all reagents and samples to room temperature before use. It is recommended that all samples, standards, and controls be assayed in duplicate.
  1.   Prepare all reagents, standard dilutions, and samples as directed in the product insert.
  2.   Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.
    3. 100 µL Assay Diluent
  3.   Add 100 µL of Assay Diluent to each well.
    4. 50 µL Standard, Control, or Sample
  4.   Add 50 µL of Standard, control, or sample to each well. Additions must be completed within 15 minutes. Cover with a plate sealer, and incubate at room temperature for 2 hours.
  5.   Aspirate each well and wash, repeating the process 3 times for a total of 4 washes.
    6. 200 µL Conjugate
  6.   Add 200 µL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 2 hours.
  7.   Aspirate and wash 4 times.
    8. 200 µL Substrate Solution
  8.   Add 200 µL Substrate Solution to each well.
  9.   For Cell Culture Supernate & Saliva Samples: Incubate at room temperature for 20 minutes. PROTECT FROM LIGHT.
    For Serum & Plasma Samples: Incubate at room temperature for 30 minutes. PROTECT FROM LIGHT.
    10. 50 µL Stop Solution
  10. Add 50 µL of Stop Solution to each well. Read at 450 nm within 30 minutes. Set wavelength correction to 540 nm or 570 nm.
