Product Summary
The Quantikine Human soluble gp130 Immunoassay is a 4.5 or 5.5 hour solid phase ELISA designed to measure sgp130 in cell culture supernates, serum, and plasma. It contains soluble insect cell-expressed recombinant human gp130 and antibodies raised against recombinant human gp130 and has been shown to accurately quantitate the recombinant factor. Results obtained using natural gp130 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 gp130.

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.

The recovery of sgp130 spiked to three different levels throughout the range of the assay in various matrices was evaluated.

Sample Type Average % Recovery Range %
Cell Culture Media (n=5) 109 96-114
Citrate Plasma (n=5) 98 84-112
EDTA Plasma (n=5) 100 83-114
Heparin Plasma (n=5) 98 85-110
Serum (n=5) 101 83-120
To assess the linearity of the assay, five samples were spiked with high concentrations of sgp130 in various matrices and diluted with the appropriate Calibrator Diluent to produce samples with values within the dynamic range of the assay.

Preparation and Storage
  • Storage
    Store the unopened product at 2 - 8 °C. Do not use past expiration date.
Background: gp130

Gp130, the common signal transducing receptor component shared by the functional receptor complexes of the IL-6 family of cytokines, belongs to the classI cytokine receptor family. Binding of IL-6 or IL-11 to either the membrane-anchored or soluble IL-6 R or IL-11 R, respectively, initiates the association of IL-6 R (IL-11 R) with gp130. The complex then undergoes homodimerization and signal transduction. For other IL-6 family cytokines, such as LIF and OSM, signal transduction is similarly triggered by the heterodimerization of gp130 with LIFR or OSM R.

    4.   Add 100 µL of Assay Diluent to each well.

    5. 100 µL Standard, Control, or Sample
    6.   Add 100 µL of Standard, control, or sample to each well. Cover with a plate sealer, and incubate at room temperature for 3 hours.
    7.   Aspirate each well and wash, repeating the process 3 times for a total of 4 washes.

    8. 200 µL Conjugate
    9.   Add 200 µL of Conjugate to each well.
    10.   For Serum & Plasma Samples: Cover with a new plate sealer, and incubate at room temperature for 1 hour.
      For Cell Culture Supernate Samples: Cover with a new plate sealer, and incubate at room temperature for 2 hours.
    11.   Aspirate and wash 4 times.
