Abrégé

Plating media contains enzyme substrates (ES) used to detect enzyme activity associated with a target organism and that include a binding motif (BM) that serves to bind detectable enzymes (DE) (also called marker enzymes in this disclosure). A signalogenic substructure (SG) produces detectable signals and an enzyme labile group (ELG) is labile to the action of a marker enzyme and it typically includes the binding motif. The enzyme labile group links to the signalogenic substructure via a labile bond (LB) which is cleaved by the action of the marker enzyme separating the signalogenic substructure and the enzyme labile group. In some embodiments a linker is inserted between the signalogenic substructure and the enzyme labile group. Presence of the enzyme and thus the organism is detected by presence of a fluorogenic, precipitate that can be detected in single colonies.

Abrégé

The present invention relates to methods for detecting the activity of an ion channel in a cell. The methods comprise providing a loading buffer solution to a cell that has an ion channel. The loading buffer comprises at least one thallium indicator (e.g., an environmentally sensitive, luminescent dye) and a physiological concentration of chloride ions. The methods further comprise providing a stimulus buffer to the cell, wherein the stimulus buffer comprises thallium (e.g., thallium ions). Providing the stimulus buffer causes thallium influx into the cell through the ion channel. After providing the stimulus buffer, the luminescence (e.g., fluorescence) of the dye in the cell is detected. The luminescence of the dye can change in the presence or absence of thallium. The methods may be used to measure influx or efflux of thallium through an ion channel.

Abrégé

Methods of reversal of the binding between a biotin compound and a biotin- binding compound are disclosed. A method of reversibly releasing a biotinylated moiety from a streptavidin (or avidin) coated support is shown as an example. The strong interaction between streptavidin or avidin-biotin is made much weaker by using a combination of modified streptavidin or avidin and modified biotin like desthiobiotin or a derivative thereof like DSB-X Biotin. A protein, such as an antibody may be biotinylated with the modified biotin. When this protein is isolated by binding the modified biotin to the modified streptavidin or avidin bound to an solid surface, it may be released under very gently and very rapid conditions by addition of free biotin. In contrast to proteins obtained by the prior art release methods the protein obtained using the previously available release methods, the proteins obtained using the methods disclosed herein will maintain their native conformation. Uses of the methods in various procedures including cell detachment procedures and techniques of detection, identification, determination, purification, separation and/or isolation of target proteins or nucleic acid molecules are also described.
