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 Mouse Insulin into health serum sample. The un-spiked serum was used as blank in this experiment.
The recovery ranged from 80% to 120% with an overall mean recovery of 110%.

| Serum | 30 | n.d.-1144.00 | 93.3 | 368.21 |
Serum/Plasma – Thirty samples from apparently healthy mice were evaluated for the presence of Insulin 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: Insulin
Insulin and the IGFs are members of the insulin family of molecules. IGF-I and II are structurally homologous to proinsulin, and can be thought of as taking the shape of an exaggerated, inverted letter G. Intrachain disulfide bonds link sections of the G. The single chain insulin propeptide consists of a 30 amino acid B chain (aa 2554), a C-peptide (aa 5589), and a 21 aa A chain (aa 90110). Removal of the C-peptide by proteolysis enables the formation of mature Insulin, a disulfidelinked heterodimer of the A and B chains. Circulating C-peptide levels are elevated in hyperinsulinism, obesity, and type II diabetes.
