The present invention provides anti-gliadin antibodies and antibody fragments, and polypeptides encoding the antibodies or fragment. Also disclosed are methods and Kits for the use of such antibodies, fragments, or polypeptides in detection of gliadin. Further provided are heavy chain and light chain variable sequences and associated sequences of complementarity-determining regions (CDRs).

A method of measuring the harshness of a surfactant, comprising the steps of: i) preparing a solid protein-dye complex comprising: a) a protein, which is a non-denatured corn protein and which is soluble in aqueous alcohol; and b) a protein binding dye, which is specific to the protein (a); by dissolving a) and b) in aqueous alcohol to form a solution of protein-dye complex; and removing the aqueous alcohol to form a solid protein-dye complex; and ii) providing an aqueous solution of surfactant and taking a first colour measurement, iii) adding the solid protein-dye complex to the aqueous solution of surfactant, taking a second colour measurement and measuring the change in colour between the first colour measurement and the second colour measurement; and iv) matching the change in colour with a reference scale; provides a quick and accurate way of assessing surfactant harshness towards protein, that can be easily carried out under non-laboratory conditions and enables suitable product recommendations to be made.

The present disclosure is directed to methods, systems and apparatuses for predictively selecting plant extracts for their inclusion in formulations to imparting anti-corrosion properties to coatings for aluminum, aluminum alloys, copper and copper alloys.

The invention relates to a method for the quantification of the total gluten content of grains in food samples. Areas of application are primarily the food industry, service laboratories and government test laboratories or biotechnology. The invention aims to quickly and cost-effectively determine the total gluten content in foods with just one measurement. We include a method with which, based on the detection of prolamins and glutelins, all potentially coeliac-relevant gluten protein fractions in food samples are quantified as a total corresponding to their mass. The method is based on the joint use of specific prolamin and glutelin antibodies as a combined conjugate according to the invention for the detection of the total gluten content. In addition, the individual antibody conjugates are thinned so that the contribution of the individual antibodies to the total signal strength corresponds to the proportion of the gluten fraction that they each detect.

A method of detecting gibberellins, for example in barley. Current methods of detecting gibberellins require dedicated equipment which makes it expensive and time consuming. A ligand bind assay for detecting gibberellins in which the above disadvantages could at least partially be overcome or alleviated is described. The ligand binding assay uses aptamers for the detection of gibberellins in barley seeds.

The present invention relates to scaffold proteins derived from plant cystatins and to nucleic acids encoding them. The scaffolds are highly stable and have the ability to display peptides. The scaffolds are particularly well suited for constructing libraries, e.g., in phage display or related systems. The invention also relates to various uses of the scaffolds, including in therapy, diagnosis, environmental and security monitoring, synthetic biology and research, and to cells and cell cultures expressing the scaffold proteins.

Provided is a polypeptide comprising a macadamia protein running in a 2D SDS PAGE at pH 6.3 to 8.7 and 53 to 67 kDa or a protein running in a 2D SDS PAGE at pH 6.5 to 7.9 and 20 to 25 kDa or an antigenic variant thereof, and a tag for detection and/or purification, a polypeptide fused with the macadamia protein, or the macadamia protein is modified by glycosylation, phosphorylation, acetylation, decarboxylation, citrullination, or hydroxylation.

Provided herein are compositions and methods useful for the analysis and authentication of polysaccharide-rich herbs, such as Dendrobium officinale, Radix Astragali, Radix Angelica Sinensis, and related herbal products.

The present invention relates to new transporter polypeptides, and genes encoding therefor, which can be used to confer upon a plant resistance to one or more biotrophic fungal pathogens.

A processing and detection system for detecting presence of at least one gluten protein in a food sample comprises a food processor including: a reservoir containing a process liquid for processing the food sample; a body that comprises a chamber configured to receive the food sample; and a pressing surface configured to press on the reservoir to cause the process liquid to exit the reservoir and mix with the food sample, thereby generating a processed food liquid; and an exit port configured to conduct the processed food liquid out of the food processor; and a cartridge including: at least one sensor configured to receive the processed food liquid and to generate an electrical signal in response to interaction with the at least one gluten protein in the processed food liquid, and an analyzer in electrical communication with the at least one sensor for detecting the electrical signal and determining the presence of the at least one gluten protein in the food sample based on the detected electrical signal.
