Human Pleural Fluid

Innovative Research's Human Pleural Fluid is collected from normal, healthy donors. The human body produces pleural fluid in small amounts to lubricate the surfaces of the pleura, the thin membrane that lines the chest cavity and surrounds the lungs.

This product is for in vitro research use only, is not to be consumed by animals or humans, and should be handled with general precaution as if capable of spreading infectious disease.
