GCP-2 (granulocyte chemotactic protein-2) is a CXC chemokine. Among human CXC chemokines, GCP-2 is most closely related to ENA-78. The structure and sequence of the genes for human GCP-2 and ENA-78 also exhibit close similarity, suggesting the two genes may have originated from a recent gene duplication. LIX (LPS-induced CXC chemokine) was initially cloned as a gene induced by LPS in mouse fibroblasts. The mouse protein designated GCP-2, because of its amino acid sequence similarity (60%) to human GCP-2, is identical to the LIX protein sequence.

Product Summary for Human CXCL6/GCP-2 Quantikine ELISA Kit
The Quantikine Human GCP-2 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human GCP-2 in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant human GCP-2 and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human GCP-2 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 natural GCP-2.

Recovery for Human CXCL6/GCP-2 Quantikine ELISA Kit
The recovery of GCP-2 spiked to levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Media (n=4) | 104 | 93-114 |
| EDTA Plasma (n=5) | 99 | 89-109 |
| Heparin Plasma (n=5) | 100 | 91-112 |
| Serum (n=5) | 95 | 88-104 |
Linearity
To assess the linearity of the assay, samples containing or spiked with high concentrations of GCP-2 were serially diluted with the Calibrator Diluent to produce samples with values within the dynamic range of the assay.

Protocols
View specific protocols for Human CXCL6/GCP-2 Quantikine ELISA Kit (DGC00):
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.
- Prepare all reagents, standard dilutions, and samples as directed in the product insert.
- Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.
- Add 100 µL of Assay Diluent to each well.
- Add 50 µL of Standard, control, or sample to each well. Cover with a plate sealer, and incubate at room temperature for 2 hours.
- Aspirate each well and wash, repeating the process 3 times for a total of 4 washes.
- Add 200 µL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 2 hours.
