Product Summary

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

Recovery

The recovery of Fetuin A spiked to levels throughout the range of the assay was evaluated.

Sample Type Average % Recovery Range %
Cell Culture Media (n=4) 103 93-109

Linearity

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

Background: Fetuin A/AHSG

Fetuins are members of the cystatin family of proteases. Secreted by the liver, fetuins can be found at high levels in serum. Fetuin A promotes phagocytosis of apoptotic cells and plays a role in bone development, calcium homeostasis and insulin sensitivity. Fetuin B functions as an inhibitor of basic calcium phosphate precipitation.

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

  5. 50 µL Standard, Control, or Sample
  6.   Add 50 µL of Standard, control, or sample to each well. Cover with a plate sealer, and incubate at room temperature for 2 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. Cover with a new plate sealer, and incubate at room temperature for 2 hours.
  10.   Aspirate and wash 4 times.

  11. 200 µL Substrate Solution
  12.   Add 200 µL Substrate Solution to each well. Incubate at room temperature for 30 minutes. PROTECT FROM LIGHT.

  13. 50 µL Stop Solution
  14.   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.
