The peritoneal cavity in mammals contains different immune cell populations crucial for innate immune responses. An efficient isolation method is required for biochemical and functional analyses of these cells. Here we provide a comprehensive method for the isolation of peritoneal cavity cells in the mouse.

FAQs
Controlled manipulation promotes contact between the lavage solution and peritoneal surfaces while dislodging material that may otherwise remain locally distributed. This helps the recovered sample represent cells, microorganisms, and soluble mediators present in the cavity. More complete mixing can support downstream cytology, immune-cell profiling, cytokine measurement, pathogen detection, and related analyses.
Pressure and duration are experimental variables rather than minor handling details. If they differ between animals, the amount and composition of recovered material may change, creating apparent biological differences that actually reflect collection technique. Consistent animal handling, pressure, and massage duration improve comparability among lavage samples and strengthen interpretation of immune or infection-related findings.
The manipulation can dislodge both resident and recruited cells, so the lavage may contain a mixture of pre-existing and inflammation-associated populations. This makes collection useful for examining cellular composition, but interpretation depends on consistent manipulation. When recovery conditions vary, apparent differences in cell abundance may reflect sampling variability rather than changes in the experimental immune response.
Researchers should standardize the lavage solution, animal handling, massage pressure, and massage duration, because each can influence how thoroughly material mixes with the peritoneal surfaces and enters the recovered fluid. Applying the same collection conditions across experimental groups helps reduce technical variation and makes differences in cytology, immune-cell profiles, cytokines, or pathogen detection easier to interpret.
A recovered lavage can support several complementary measurements. Cytology provides information about cellular material, while immune-cell profiling examines the recovered populations more specifically. Cytokine measurement assesses soluble mediators, and pathogen detection targets microorganisms. Using these analyses together can connect cellular, soluble, and infectious features of the peritoneal response within the same research framework.
The peritoneal cavity can contain resident or recruited immune cells, microorganisms, and soluble mediators that change during an experimental response. Recovering these materials in lavage enables researchers to examine multiple features of that response rather than relying on a single measurement. The approach is therefore relevant for comparing immune-cell composition, cytokine signals, and pathogen presence across experimental groups.
