Abstract
Intraperitoneal (i.p.) injection of thioglycollate elicits a robust influx of neutrophils into peritoneal cavity. The trafficking of the cells is believed to be mediated by chemokines CXCL1, CXCL2, and CXCL8 (Call et al., 2001; Cacalano et al., 1994). Thus this model can be used to test the ability of neutrophils to migrate towards these chemokines in bioengineered mouse strains (e.g. knockout or transgenic mice) or the ability of certain molecules to inhibit the chemoattractive activities of these chemokines (e.g. small molecules or inhibitory antibodies). This protocol has been used by the author successfully to test the functions of a viral multi-chemokine inhibitor.

Notes
Some protocols prefer to decide cell numbers simple by counting cells using hemocytometer. The numbers obtained by such method may not accurately reflect the number of neutrophils because there are other types of cells such as B1 B cells and macrophages in peritoneal cavity.
