Product Summary

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

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

Background: CCL27/CTACK

CCL27, also known as Cutaneous T cell-attracting chemokine (CTACK), ALP, ILC and ESkine, is a CC chemokine discovered using expressed sequence tags (EST) in a homology search for novel chemokines. Mature human and mouse CCL27 are 84% similar. Mouse CCL27 shares 37% and 35% amino acid identity with mouse MIP-3 beta and mouse TECK, respectively. CCL27 is predominantly expressed in the skin. The expression is up-regulated by proinflammatory cytokines.

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 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.
