Abstract:
Provided herein are methods for detecting an Aspergillus protease in a sample, diagnosing a subject with aspergillosis caused by an Aspergillus infection based on the presence of an Aspergillus protease in a sample, and methods of aspergillosis treatment that incorporate these diagnostic methods. In certain embodiments, the Aspergillus protease is Asp f2, and the Aspergillus infection is caused A. fumigatus, A. flavus, A. versicolor, A. niger, or A. terreus. Also provided herein are antibodies and kits for use in these methods, including novel antibodies specific for Asp f2.
Abstract:
The present disclosure relates to in vitro methods of predicting rumen digestible protein of a feed sample. An in vitro method of predicting rumen digestible protein of a feed sample includes forming an aqueous test composition including the feed sample, a buffer, and one or more digestive enzymes. The method includes incubating the test composition. The method includes removing one or more test samples of the test composition at time points during the incubating, the time points including about 0 h and at least one time point after about 0 h. The method includes measuring soluble protein content of the one or more test samples. The method includes using the measured soluble protein content of the one or more test samples to predict a rate and/or extent of rumen protein digestion of the feed sample.

Abstract:
Prolyl endopeptidase (PE) activity in lung samples is detected by contacting the lung sample with a probe comprising a —P—X— (or —X—P—, —P—X—P—) PE recognition site, wherein P is a prolyl bioisostere, X is a residue that is not a prolyl bioisostere or is a prolyl bioisostere flanked on each side by a residue that is not a prolyl bioisostere, and “-” is an amide bond, under conditions wherein PE activity of the sample specifically hydrolyzes an amide bond of the recognition site to generate an optical signal; and (b) detecting the signal.
