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%.
Sample Values

|---|---|---|---|---|
| Human Serum | 30 | 200.7-417.0 | 100 | 304.2 |
Serum/Plasma – Thirty samples from apparently healthy volunteers, two samples from healthy monkeys and five samples from healthy canines were evaluated for the presence of human EGF 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: 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.
