摘要:
The invention relates to methods of capturing bacterial whole cells that includes the use of one or more antibodies having antigenic specificities for one or more distinct analytes characteristic of the specific bacterium, followed by analyzing the target whole cells using a direct or indirect ATP assay.
摘要:
The application discloses embodiments of detection devices including a sensor component in a flow path between a first flow path portion and a second flow path portion. In embodiments described, the sensor component includes a receptor in a polymerized composition. The receptor is configured to bind with an analyte in a test sample. Upon binding the sensor component undergoes a detectable change in response to interaction of the analyte with the receptor.
摘要:
The invention relates to devices and methods for analyzing a sample (and preferably preparing a sample), which is particularly used in analysis, such as analysis of a sample for a bacterium of interest.
摘要:
An apparatus assembly for detecting an analyte in a sample of material includes a valve, a frame, and a plurality of housing segments. The valve may be actuated to adjust a flow path and flow rate through the housing segments.

摘要:
A shock indicator is described comprising (A) a base having a first side and a second side; (B) an indicator associated with the first side of the base, the indicator comprising a plurality of indicator subparts, the subparts comprising solid material arranged (i) in a first configuration when the shock indicator is in a first state prior to a shock event, and (ii) in a second configuration when the shock indicator is in a second state following a shock event; and (C) means associated with the second side of the base for attachment of the shock indicator to a surface. A method of manufacture is also provided.
摘要:
Time or time-temperature indicating articles are described comprising a housing enclosing: (a) a first fluid reservoir at least partially filled with a first fluid; (b) a substrate comprising a plurality of channels; (c) a second fluid reservoir in fluid communication with at least one channel of the substrate; and (d) a barrier located between the first fluid reservoir and the second fluid reservoir. The article can be manipulated at a desired point in time by opening the barrier to allow at least a portion of the fluid to flow from the first reservoir to the second reservoir and to contact at least one channel of the substrate. The article is designed to provide an indication of the progress of the fluid as it moves through the channels of the substrate.
摘要:
A method of controlling a multi-step decontamination process is disclosed. The method comprises assigning articles into a plurality of groups, processing the articles through a first and/or second sub-process of the multi-step decontamination process, quantifying a biological analyte associated with residue on or in the processed articles, and setting action limits for the first and second sub-processes. A method and a system for monitoring the control of the decontamination process are also disclosed.
