I want to Isolate the macrophages from the peritoneal cavity of balb/c mice but after several try I could not have done this. Is there any body help me or suggest me any alternative and easiest way to do that above mentioned job.

Hi! Just try searching for the protocol using Solutions Search - present in the tabbed box above. I've already posted in a detailed protocol for both resident and thioglycollate elicited macrophages - contact me if you need any clarifications.
best,
