    Abstract: Assay devices are provided including a receptacle having a sample entry port; a plunger disposed within the receptacle; at least one reagent; a membrane attached to a first surface of the plunger; a wick providing capillary force; and a detection zone. The membrane includes a target conjugate zone in which affinity components are disposed. Capture compounds are immobilized in a detection zone, which is located between the target conjugate zone and the wick. A method of detecting a target analyte is also provided, including providing the assay device; providing a sample suspected to contain a target analyte; adding the sample onto the device; allowing the sample to travel along the membrane until the sample reaches the detection zone; immobilizing the target analyte through reaction of the target analyte with the capture compounds; reacting the immobilized target analyte with a reagent to generate a detectable signal; and detecting the generated signal.

    Abstract: The present disclosure provides a culture device for enumerating colonies of microorganisms. The device can comprise a base, a coversheet, and a nonporous spacer member disposed therebetween. The spacer member comprises an aperture that defines a growth compartment. Disposed in the growth compartment are a cold water-soluble gelling agent, a dry oxygen-scavenging reagent, a dry buffer system, and an effective amount of a dry carbon dioxide-generating reagent. The buffer system is selected such that, when the growth compartment is hydrated with a predetermined volume of deionized water, an aqueous mixture with a pH less than or equal to 6.35 is formed.

    Abstract: A selective microbial detection device and methods of use are provided. The device includes a water-proof pouch that includes a first wall portion, a second wall portion, and a porous membrane filter disposed in the pouch between the first and second wall portions. The filter membrane divides the pouch into first and second compartments. The microbial detection device also includes an effective amount of a dry nutrient disposed in the first compartment, which contains sodium lauryl sulfate in an amount of 1.75 milligrams or greater per twelve square inches of the first wall portion. A dry, cold water-soluble gelling agent is adhered to the pouch in the first compartment and an absorbent pad is disposed in the second compartment. A sealable sample port provides access to deposit a liquid into the first compartment.
