Area of Science:

  • Animal Science
  • Biochemistry
  • Proteomics

Background:

  • Intestinal health is crucial for overall pig well-being and productivity.
  • Alterations in the intestinal mucosal layer can negatively impact pig health.
  • Standardized methods for proteomic analysis of pig intestinal mucosa are lacking.

Purpose of the Study:

  • To evaluate and establish a standardized protocol for protein extraction from pig ileal mucosal scrapings.
  • To optimize sample preparation for mass spectrometry-based proteome analysis.
  • To enhance future research on pig intestinal health and productivity.

Main Methods:

  • Evaluated three S-trap-based protein extraction protocols for pig ileal mucosal scrapings.
  • Compared freeze-dried solid samples versus liquid nitrogen-ground samples.
  • Utilized mass spectrometry-based proteome analysis to identify proteins.

Main Results:

  • Identified a total of 2840 proteins across all analyzed samples.
  • Statistical and gene ontology analyses showed no significant differences between the three tested methods.
  • The freeze-dried solid sample protocol was identified as the most convenient and practical.

Conclusions:

  • The freeze-dried, solid-state sample protocol is recommended for consistent and reliable protein extraction from pig intestinal mucosa.
  • Establishing this standardized protocol addresses a critical gap in pig research.
  • This advancement will facilitate deeper understanding of pig intestinal health and inform strategies for improved productivity.
