A further high-sensitive method for detection, determination, and activity measurement of peroxidase with no special enhancer argent. The substance, for example, high-concentration ammonium sulfate, is dissolved in the reaction solution to give rise to the micro-hydrophobic property, for detection, determination, and activity measurement of peroxidase using luminol and hydrogen peroxide as substrates.

A process for manufacturing particles of water-absorbing material is provided. The process includes providing a powder bed composed of an absorptive powder comprising a water-absorbing polysaccharide onto a surface; releasing an aqueous solution from a solution dispenser so as to contact the powder bed, 5 thereby forming a solution-impregnated humid material; letting the solution-impregnated humid material agglomerate in substantially shear-less conditions to form an agglomerated humid material, the solution-impregnated humid material being supported by the surface; and drying the agglomerated humid material, thereby forming the particles.

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.

A NADPH oxidase (Nox) protein includes a domain including 3 to 7 transmembrane helices, and an amino acid sequence including at least 2 bis-histidyl motifs, wherein each of the bis-histidyl motifs consists of 2 histidine residues separated by 12, 13 or 14 amino acid residues. The Nox protein may be produced by a method that includes solubilizing a solution of cells expressing the Nox protein using a detergent from the maltoside family to suspend the Nox protein in the solution.

Chromogenic conjugates for color-based detection of targets are described. The conjugates comprise a chromogenic moiety such as rhodamine, rhodol or fluorescein. The chromogenic moiety is linked to a peroxidase substrate. The chromogenic conjugates can be used in immunohistochemical analysis and in situ hybridization. The conjugates can be used to detect 1, 2, 3 or more targets in a sample by color.
