Rat lung tissue is a site of alpha 1-proteinase inhibitor synthesis: evidence by cell-free translation.
Poly(A) +RNA isolated from lungs of normal rats and of rats suffering from experimental inflammation was translated in a cell-free translation mixture from rabbit reticulocytes. The translation products were immunoprecipitated with specific antisera against alpha 1-proteinase inhibitor and alpha 2-macroglobulin. Comparable levels of mRNA for alpha 1-proteinase inhibitor were found in rat lung tissue from control and experimentally inflamed animals. alpha 2-Macroglobulin mRNA could not be detected in rat lung tissue.
