Human PR3 (Proteinase 3) ELISA Kit (HUES02909)

From Assay Genie, this sandwich ELISA is designed for the precise quantitative detection of Proteinase 3 (PR3) in human serum, plasma, and other biological fluids. The assay uses a colorimetric detection method with a run time of 3 h 30 min, and absorbance is read at 450 nm ± 2 nm against a standard curve.

Proteinase 3 is an enzyme involved in immune responses and inflammatory processes, and its dysregulation has been linked to autoimmune conditions such as vasculitis and rheumatoid arthritis, supporting its use as a biomarker in research. The kit specifically recognises Human PR3, with no significant cross-reactivity or interference observed between Human PR3 and analogues.

Quoted performance figures include a sensitivity of 0.1 ng/mL, a detection range of 0.16–10 ng/mL, and a recovery of 80%–120%. The recommended sample volume is 100 μL. The kit is intended for research applications in cancer and signal transduction, and components should be stored at 2–8°C.
