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 EGF into health human serum sample. The un-spiked serum was used as blank in this experiment.
The recovery ranged from 78% to 106% with an overall mean recovery of 93%.

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: EGF
EGF (Epidermal Growth Factor) is expressed as a transmembrane protein that is proteolytically cleaved to generate soluble forms. It signals through EGF R/ErbB1 which heterodimerizes with ErbB2, ErbB3, or ErbB4 and can also associate with PDGF R beta and HGF R/c-MET. During development, EGF regulates thymocyte differentiation, neuroglia production, and adipocyte maturation. In the adult, EGF plays a role in mammary gland lactogenesis, fibroblast mitosis, dissociation of the extracellular matrix, and cell migration.
