Lung clearance assay tests the ability of innate immune cells (mainly NK cells) to eradicate in vivo cells injected via the tail vein of the mice. This assay helps to elucidate the role played by NK cells and their receptors (if the mice are genetically modified) against various human and mouse targets in an in vivo setting (Stern-Ginossar et al., 2008; Halfteck et al., 2009; Tsukerman et al., 2012).

Antibodies To demonstrate that the observed effect is specific we recommend to either blocking the relevant receptors, or by depleting NK cells, by using anti-NK1.1 (in case the receptor is present), or by using anti-asialo GM1.
