Murine cytokines were measured using a standard sandwich ELISA methods, as previously described [18] (link), [19] (link). The capture antibodies, detection antibodies and recombinant cytokines were purchased from R&D Systems. The ELISAs used in this study did not cross-react with other known murine cytokines. For lung cytokine measurements, lungs were homogenized in PBS containing 0.1% TritonX-100 and complete protease inhibitor (Roche) and centrifuged; the cleared supernatants were harvested and used for ELISAs.
