Intra-assay Precision (Precision within an assay) Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.
Inter-assay Precision (Precision between assays) Three samples of known concentration were tested six times on one plate to assess intra-assay precision.
Spike Recovery
The spike recovery was evaluated by spiking 3 levels of human IL-5 into health human serum sample. The un-spiked serum was used as blank in these experiments.
The recovery ranged from 88% to 115% with an overall mean recovery of 106%.
Sample Values

Serum/Plasma – Thirty samples from apparently healthy volunteers were evaluated for the presence of IL-10 in this assay. No medical histories were available for the donors.
n.d. = non-detectable. Samples measured below the sensitivity are considered to be non-detectable.
Product Data Sheet
Background: IL-5
IL-5 (Interleukin-5) is a secreted cytokine that is expressed as a covalent dimer. It is produced by activated Th2 cells, eosinophils, mast cells, and iNKT cells and promotes eosinophilic and basophilic differentiation and activation. IL-5 signals through a receptor complex containing IL-5 R alpha and the Common beta Chain/CD131 on eosinophils and basophils. Naturally occurring soluble forms of IL-5 R alpha retain the ability to bind IL-5 and limit its bioavailability.
