摘要： A method for expressing proteins as a fusion chimera with a domain of p26 or alpha crystallin type proteins to improve the protein stability and solubility when over expressed in bacteria such as E. coli is provided. Genes of interest are cloned into the multiple cloning site of the Vector System just downstream of the p26 or alpha crystallin type protein and a thrombin cleavage site. Protein expression is driven by a strong bacterial promoter (TAC). The expression is induced by the addition of 1 mM IPTG that overcomes the lac repression (lac Iq). The soluble recombinant protein is purified using a fusion tag.

摘要： A device and method for detecting the presence or absence of a prokaryotic microorganism are provided, comprising the steps of identifying a protein, such as a microbial-specific protease that characterizes the presence of a specific prokaryotic microbe and thereby provides a marker for that microbe; detecting the protease that is a marker for the presence of a specific prokaryotic microbe by cleaving a substrate when the protease is present; and signaling the presence of that protease when cleavage has occurred. More specifically, the method comprises identifying at least one outer membrane protein or a secreted protein that is unique to a particular microbial pathogen such as for example Listeria monocytogenes and that is substrate specific.

摘要： Described herein are zymogens, methods of use for zymogens, and devices that incorporate zymogens. The zymogens include a substrate and an enzyme. The substrate can inhibit the enzyme and is a target for a protein produced by a microorganism. When the substrate is modified by a protein produced by a microorganism, the enzyme is activated. The zymogens can be used to amplify detection assays.
