One aspect of the present disclosure can include a method for reducing or alleviating inflammation in the digestive tract of a subject in need thereof that consumes a disruptive dietary component. One step of the method can include assaying a previously obtained fecal sample from the subject for the presence of one or more Proteobacteria and an activity level of a peroxidase enzyme. The subject can decrease ingestion of the disruptive dietary component if the assayed presence of the one or more Proteobacteria and the activity level of the peroxidase enzyme are increased as compared to control levels.

A method for labeling concentration density differentials of an analyte in a biological sample is provided. The method may including the steps of: binding an enzyme to an analyte contained in a sample, the enzyme capable of acting on at least two chromogens; incubating the sample with a first chromogen for a first time period to generate a first color chromogen-enzyme product, the first color chromogen-enzyme product reflecting light observable as a first color; and incubating the sample with a second chromogen for a second time period to generate a second color chromogen-enzyme product, the second color chromogen-enzyme product reflecting light observable as second color. A combination of the light observable as the first color and the light observable as the second color may be observable as a third color, and each color may describe a different analyte density in the biological sample.

Multifunctional molecular weight protein ladders and methods of making thereof are disclosed herein that are useful for determining the molecular weight of a test protein and/or the relative mass or amount of the test protein in a protein separation assay, such as gel electrophoresis or western blotting. Also included are compounds of Formula I (e.g., mono acetylated MP-11 NHS ester) that may be used to label purified proteins of the protein ladder. The MP-11 label protein ladder can be detected on a blotting membrane by exposing the microperoxidase to a suitable substrate, such as a chromogenic substrate or a chemiluminescent substrate.

Provided is a component measuring apparatus configured to determine a functional form that describes wavelength characteristics of a variation attributable to scattering (S ()). The apparatus then determines unknown one or more coefficients (p, q) based on a first relational expression that involves a variation attributable to absorption (H (1)) and a group of second relational expressions that do not involve variations attributable to absorption (H (2a), H (2b), H (2c)). The apparatus then corrects an absorbance measured at an arbitrary wavelength () using a function where the one or more coefficients (p, q) are applied to the functional form so as to reduce or eliminate at least the effects of scattering of light.

Self-indicating chemistries are provided for visual detection by a user of efficacious levels of peroxycarboxylic acid concentrations in a solution produced in situ. The self-indicating chemistries include a combination of dyes providing a visual color indication, such as a tri-color indicator system, such as a yellow, green, and red color system indicating in situ threshold levels of peroxycarboxylic acid concentrations in a solution employing the self-indicating chemistry. Systems, kits and compositions for a quantitative assessment of an in situ perhydrolysis reaction to generate peroxycarboxylic acids are provided. Methods of use are further provided.

Secreted proteins as detection markers for insect vector and graft transmitted citrus disease are described. Method and kits for detecting the secreted proteins are provided.

The current disclosure provides sensitive diagnostic methods that do not require invasive laparoscopic surgery. It was found that monomeric myeloperoxidase (MPO) was found in cells, tissues, and the sera of patients with endometriosis. This novel biomarker can be used to detect ovarian and endometrial hyperproliferative disorders. Accordingly, aspects of the disclosure relate to a method for evaluating a subject comprising detecting monomeric myeloperoxidase (MPO) in a biological sample from the subject. Also disclosed is a method for treating a subject with an endometrial or ovarian hyperproliferative disorder, the method comprising administering an treatment for the endometrial or ovarian hyperproliferative disorder to a subject that has had the level of monomeric MPO evaluated in a biological sample from the subject.

A granule for detecting glucose in pet urine, includes: 80-100 parts by weight of a filler, 30-50 parts by weight of water-absorbent material, 2-4 parts by weight of a bacteriostatic agent, 5-10 parts by weight of an adhesive, 1-2 parts by weight of glucose oxidase, 2-4 parts by weight of peroxidase, 2-6 parts by weight of an indicator.

Methods and analyte sensors including at least a first working electrode having a first active area thereon, and performing a dip coating operation to deposit a bilayer membrane upon the first working electrode and the first active area. The bilayer may include an inner layer having a first membrane polymer and an outer layer having a second membrane polymer, the first membrane polymer and the second membrane polymer differing from one another. The dip coating operation may comprise one or more first dips in a first membrane formulation to form the inner layer of the bilayer membrane and one or more second dips in a second membrane formulation to form the outer layer of the bilayer membrane upon the inner layer.

Methods measuring properdin function and kits for conducting ELISA assays using anti-properdin antibodies and uses thereof are described.
