• This study aims to improve lymphocyte isolation techniques.

Purpose of Study

• To develop a more effective method for isolating lymphocytes from PPs.
• To facilitate functional assays and flow cytometry studies.
• To enhance the understanding of T and B cell populations in mice.

Methods Used

• Mouse preparation and sterilization.
• Midline abdominal incision to access Peyer's Patches.
• Separation of the small intestine from the cecum.
• Isolation of lymphocytes without collagenase digestion.

Main Results

• Successful isolation of high-quality lymphocytes.
• Improved identification of follicular T helper and germinal center B cells.
• Reduction in laborious preparation steps.
• Enhanced applicability for functional assays.

Conclusions

• The new protocol significantly improves lymphocyte isolation.
• It provides a reliable method for studying immune cell subsets.
