Intra-assay Precision (Precision within an assay) Three samples of known concentration were tested twenty-two 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 Elafin/PI3 into health human serum sample. The un-spiked serum was used as blank in this experiment.
The recovery ranged from 85% to 118% with an overall mean recovery of 102%.

Serum/Plasma – Thirty samples from apparently healthy volunteers were evaluated in this assay. No medical histories were available for the donors.
Product Data Sheet
Background: Elafin/PI3
Trappin-2 is a member of the trappin family that includes the SLPI (secretory leukocyte protease inhibitor) protein. Elafin or ESI (elastase-specific inhibitor) and SKALP (skin-derived anti-leukoproteinase) are alternative names for trappin-2 and reflect its protease targets. However, Elafin and SKALP sometimes correspond only to the processed form that contains the C-terminal WAP domain of the molecule.
