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 GM-CSF into health human serum sample. The un-spiked serum was used as blank in this experiment.
The recovery ranged from 75% to 100% with an overall mean recovery of 84%.

Serum/Plasma – Thirty samples from apparently healthy volunteers were evaluated for the presence of IL-8 in this assay. No medical histories were available for the donors.
Product Data Sheet
Background: GM-CSF
GM-CSF (Granulocyte-Macrophage Colony Stimulating Factor) induces the development of monocytes, neutrophils, eosinophils, and myeloid and dermal dendritic cells. It also acts as a neutrophil and dendritic cell chemoattractant. GM-CSF promotes Th1 and Th17 cell mediated autoimmune inflammation as well as the inflammatory activation of dendritic cells, microglia, alveolar macrophages, and eosinophils. In addition, it cooperates with G-CSF in promoting tumor cell proliferation and invasion. GM-CSF signals through a receptor complex composed of GM-CSF R alpha and the Common beta Chain (beta c) with Syndecan-2 as a potential co-receptor. The beta c subunit is shared by the receptor complexes for IL-3 and IL-5.
