QuickStep Human POSTN/OSF-2 (Periostin) ELISA Kit

A sandwich-format colorimetric immunoassay from Assay Genie, this QuickStep ELISA Kit is designed for the quantitative measurement of human Periostin (POSTN/OSF-2) in serum and plasma samples, using a 50 μL sample volume per well. According to the manufacturer, Periostin (also known as OSF-2 or Postn) is a key protein involved in various biological processes, particularly tissue development, wound healing, and cancer progression.

The assay has a reported sensitivity of 1.52 ng/mL and a detection range of 3.12-200 ng/mL, with a total run time of 1 h 30 min. Recovery is stated as 80%-120%, and the manufacturer reports no significant cross-reactivity or interference between human POSTN/OSF-2 and analogues. Kit components are stored at 2-8°C. The kit is intended for research applications in Cancer, Cardiovascular, Signal Transduction, and Tags and Cell Markers, and the QuickStep format is described by Assay Genie as saving 1-2 hours of assay time compared with conventional ELISA workflows.
