Product Summary

The Quantikine Human MCP-3 Immunoassay is a 4.5 hour solid phase ELISA designed to measure MCP-3 levels in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant human MCP-3 and antibodies raised against the recombinant factor. Results obtained for naturally occurring human MCP-3 showed linear curves that were parallel to the standard curves obtained using the kit standards. These results indicate that this kit can be used to determine relative mass values for natural human MCP-3.

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

Recovery

The recovery of MCP-3 spiked to levels throughout the range of the assay in various matrices was evaluated.

Sample Type Average % Recovery Range %
Cell Culture Media (n=4) 106 92-115
EDTA Plasma (n=5) 101 88-111
Heparin Plasma (n=5) 98 85-114
Serum (n=5) 94 86-110

Linearity

To assess the linearity of the assay, samples containing and/or spiked with high concentrations of MCP-3 were serially diluted with the appropriate Calibrator Diluent to produce samples with values within the dynamic range of the assay.

Background: CCL7/MCP-3/MARC

Human MCP-3 and mouse MARC are members of the CC subfamily of chemokines and are monocyte chemoattractants. Sequence comparisons suggest that MARC may be the mouse homolog of the human MCP-3 gene. Except for one amino acid subsititution, mouse MARC is identical to mouse FIC, the product of a growth factor-activated gene.

Entrez Gene IDs:
6354 (Human); 20306 (Mouse)
Alternate Names:
C-C motif chemokine 7; CCL7; chemokine (C-C motif) ligand 7; FIC; MARC; MCP-3; MCP3Monocyte chemotactic protein 3; MCP-3Small-inducible cytokine A7; MGC138465; Monocyte chemoattractant protein 3; NC28SCYA6; SCYA7MGC138463; small inducible cytokine A7 (monocyte chemotactic protein 3)

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.
