Quantification

In this sandwich ELISA, chemokine (C-C motif) ligand 11 in the sample is captured between a pre-coated capture antibody and a detection antibody. Signal intensity is proportional to analyte concentration. Quantification uses a standard curve fitted with Curve Expert software, covering 31.25 pg/mL-2000 pg/mL with a minimum detectable dose of 7.8 pg/mL.

For research use only (RUO). Not intended for diagnostic or therapeutic purposes. Validated in human serum, plasma, cell culture supernates, tissue homogenates matrices only.

Function
In response to the presence of allergens, this protein directly promotes the accumulation of eosinophils, a prominent feature of allergic inflammatory reactions. Binds to CCR3.
