Eotaxin-2, also named myeloid progenitor inhibitory factor 2 (MPIF-2), is a member of the CC chemokine subfamily and is designated CCL24. Eotaxin-2 is constitutively expressed in the jejunum and spleen. It can also be induced in the lung by allergen challenge and IL-4. Mouse Eotaxin-2 precursor protein shares approximately 58% amino acid sequence identity with human Eotaxin-2.

Product Summary for Human CCL24/Eotaxin-2/MPIF-2 Quantikine ELISA Kit
The Quantikine Human Eotaxin-2 Immunoassay is a 4.5 hour solid phase ELISA designed to measure Eotaxin-2 levels in cell culture supernates, serum, and plasma. It contains E.coli-expressed recombinant human Eotaxin-2 and antibodies raised against the recombinant factor. Results obtained for naturally occurring human Eotaxin-2 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 Eotaxin-2.

Recovery for Human CCL24/Eotaxin-2/MPIF-2 Quantikine ELISA Kit
The recovery of Eotaxin-2 spiked to three different levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Media (n=4) | 78 | 72-84 |
| EDTA Plasma (n=4) | 104 | 82-117 |
| Heparin Plasma (n=4) | 99 | 80-115 |
| Serum (n=4) | 103 | 84-116 |
Linearity
To assess the linearity of the assay, samples containing or spiked with high concentrations of Eotaxin-2 in various matrices were diluted with the appropriate Calibrator Diluent to produce samples with values within the dynamic range of the assay.
