Abstract: A peptide or protein microassay method and apparatus in which a wide variety of chromogenic or fluorogenic peptide or protein substrates of interest are individually suspended or dissolved in a hydrophilic carrier, with aliquots of each substrate being deposited in an array or microarray of reaction loci, or “dots.” Each dot, therefore, provides an individual reaction vessel containing the peptide or protein of interest, to which a biological sample may be applied for assay purposes. The sample is applied to the array or microarray of dots by one of a variety of focused sample application techniques, including aerosolizing or misting of the sample, or target application of the sample, onto each dot without creating fluid channels between the dots which would cause cross-contamination. In additional aspects, the present invention provides methods of transferring samples from an electrophoretic gel to a target plate for subsequent MALDI MS analysis.

Abstract: The instant invention is drawn to methods useful for the treatment or the prevention of a viral infection. The methods include administering at least one compound that is an inhibitor of cathepsin L to an individual. The methods are particularly useful in individuals infected with, or at risk of infection with, SARS virus or Ebola virus. The invention also includes methods of identifying potential therapeutics for use in the methods of treatment or prevention of a viral infection.
