Product Summary
The Quantikine Human MDC Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human MDC in cell culture supernates, serum, or plasma. It contains E. coli-expressed recombinant human MDC and has been shown to accurately quantitate the recombinant factor. Results obtained using naturally expressed human MDC 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 expressed human MDC.

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

Preparation and Storage
  • Storage
    Store the unopened product at 2 - 8 °C. Do not use past expiration date.
Background: CCL22/MDC
Macrophage-derived chemokine (MDC), also named stimulated T cell chemotactic protein (STCP-1) and ABCD-1, and now designated as CCL22, is a CC chemokine initially isolated from clones of monocyte-derived macrophages. At the amino acid sequence level, MDC shows less than 35% identity to other CC chemokine family members. Human MDC is expressed in dendritic cells, macrophages and activated monocytes. In addition, MDC expression is detected in thymus, lymph node and appendix tissues. At the amino acid sequence level, mouse and human MDC share 64% identity and 83% similarity.

Assay Procedure
Refer to the product for complete assay procedure.

It is recommended that all samples and standards 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. 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 2-8 °C for 2 hours.
  7.   Aspirate each well and wash, repeating the process 3 times for a total of 4 washes.

  8. 200 µL cold Conjugate
  9.   Add 200 µL of Conjugate to each well. Cover with a new plate sealer, and incubate at 2-8 °C 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.
