Human Peptidase Inhibitor 3, Skin Derived (PI3) ELISA Kit

Peptidase Inhibitor 3 (PI3), also called SKALP or elafin, is a secreted serine protease inhibitor expressed by epithelial cells and implicated in skin inflammation, pulmonary injury, and tumor microenvironment biology. This quantitative immunoassay kit from Assay Genie is built around a microplate strip layout and targets the human form of PI3 for research laboratory measurements.

Applications include in vitro dermatology studies of wound healing, respiratory research on protease-antiprotease imbalance, and oncology workups examining epithelial barrier integrity. The kit supports cell culture supernatant analysis and tissue homogenate work, giving investigators flexibility across disease models. Each kit ships with pre-coated wells, detection antibodies, standards, wash buffer, and substrate reagents sufficient for 96 individual assays, intended for research use only.

Reactivity is limited to human samples, and the workflow uses an absorbance readout compatible with standard laboratory microplate readers. For teams establishing baseline PI3 concentrations in epithelial tissues or screening patient-derived specimens, this kit provides a reproducible, microplate-based quantitative immunoassay.
