Development and application of a pig IL-8 ELISA detection system

Area of Science:

• Immunology
• Biochemistry

Background:

• Interleukin 8 (IL-8) is a key chemokine involved in inflammatory processes, particularly neutrophil activation.
• Accurate measurement of IL-8 is crucial for understanding and managing inflammatory conditions.

Purpose of the Study:

• To develop and validate a specific enzyme-linked immunosorbent assay (ELISA) for quantifying pig Interleukin 8 (IL-8).
• To provide a reliable and efficient method for measuring IL-8 concentrations in various biological samples.

Main Methods:

• Development of a streptavidin-biotin amplified sandwich ELISA using specific mouse monoclonal antibodies (mAbs) against recombinant pig IL-8.
• Validation of the assay for specificity, reproducibility, and working range using recombinant and natural pig IL-8.

Main Results:

• The developed pig IL-8 ELISA demonstrated high specificity and reproducibility for both recombinant and natural pig IL-8.
• The assay has a working range of 16-1000 pg/mL and requires only 3.5 hours of incubation.
• The assay accurately measures IL-8 concentrations in cell culture supernatants and biological fluids.

Conclusions:

• The newly developed pig IL-8 ELISA is a sensitive, specific, and rapid method for IL-8 quantification.
• This ELISA serves as a valuable alternative to time-consuming and labor-intensive IL-8 bioassays in research and diagnostics.
• The assay facilitates the study of inflammatory processes in pigs through precise IL-8 measurement.
