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.
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.
Cell Culture Supernates
Serum, EDTA Plasma, Heparin Plasma
The recovery of Eotaxin-2 spiked to three different levels throughout the range of the assay in various matrices was evaluated.
Average % Recovery
Cell Culture Media (n=4)
EDTA Plasma (n=4)
Heparin Plasma (n=4)
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.
Preparation and Storage
Store the unopened product at 2 - 8 °C. Do not use past expiration date.
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.
