Abstract: In one aspect, the disclosure relates to compositions comprising alpha-1-antitrypsin (AAT) and the production thereof. In some embodiments, the AAT is recombinantly produced. The disclosure also relates to methods of administering compositions comprising alpha-1-antitrypsin (AAT).

Abstract: This invention relates to coating invasive devies with novel biologically active molecules which bind to and inhibit thrombin. These molecules comprise a catalytic site directed moiety (CSDM) of the formula: ##STR1## wherein X is hydrogen or is characterized by a backbone chain consisting of from 1 to 100 atoms; R.sub.1 is selected from the group consisting of unsubstituted, mono-substituted, di-substituted and tri-substituted saturated ring structures; R.sub.2 is a bond or is characterized by a backbone chain consisting of from 1 to 5 atoms; R.sub.3 is a bond or is characterized by a backbone chain consisting of from 1 to 3 atoms; R.sub.4 is any amino acid; R.sub.5 is any L-amino acid which comprises a guanidinium- or amino-containing side chain group; R.sub.6 is a non-amide bond; and Y is characterized by a backbone chain consisting of from 1 to 9 atoms; or the formula: ##STR2## wherein R.sub.
