Product Summary
The Quantikine Human MMP-9/NGAL Complex Immunoassay is a 4.5 hour solid phase ELISA designed to measure the MMP-9/NGAL complex in cell culture supernates, serum, plasma, urine, and saliva. It contains natural human MMP-9/NGAL as the standard. The antibodies were raised against recombinant human MMP-9 and recombinant human NGAL. This kit will not detect recombinant human MMP-9 or NGAL in their free forms.

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 natural human MMP-9/NGAL Complex spiked to levels throughout the range of the assay in various matrices was evaluated.

Sample Type Average % Recovery Range %
Cell Culture Media (n=4) 90 84-97
Urine (n=4) 93 86-106
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of natural MMP-9/NGAL Complex were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.

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 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 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. Cover with a new plate sealer, and incubate at room temperature for 1 hour.
  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.
