The invention relates to the field of bioengineering, particularly to a method for improving properties of wheat germ protein with ultrasonic wave. The method comprises extracting albumin and globulin from defatted wheat germ powder, respectively, and treating wheat germ albumin and globulin solution with ultrasonic wave. The inventive method can remarkably improve the solubility, effervescence, effervescent stability, emulsifying property and emulsifying stability of the wheat germ albumin and globulin.

The invention provides, inter alia, conjugates of a hydratable polymer (such as PEG, polyethylene glycol) and a lectin (such as wheat germ agglutinin, WGA), compositions comprising these conjugates, as well as methods and targeted uses of these conjugates and compositions for, e.g., lubricating, maintaining hydration of, rehydrating, and / or inhibiting microorganism colonization of a biological surface in need thereof.

The invention discloses the application of wheat germ agglutinin in the preparation of products for inhibiting coronaviruses. The invention finds for the first time that the wheat germ agglutinin is effective against SARS‑CoV, MERS‑CoV, SARS‑CoV‑2 and SARS‑CoV‑2 mutant strains. It has good antiviral activity, and also shows certain antiviral activity to vesicular stomatitis virus (VSV), which can be used to treat and prevent infection caused by coronavirus, and can be used as a candidate drug for the prevention and treatment of coronavirus infection. Good application value.

The invention discloses a composition capable of improving stress resistance of hybrid liriodendron body embryo seedlings and realizing a promoting effect. The composition is prepared from 5 to 10 parts of wheat germ agglutinin, 5 to 10 parts of peanut agglutinin, 5 to 10 parts of sodium lignosulphonate, 5 to 10 parts of high-dispersion silicic acid, 10 to 20 parts of sodium dodecyl sulfonate and70 to 140 parts of kaolin. According to the composition disclosed by the invention, massive experiments are conducted for screening; the wheat germ agglutinin and the peanut agglutinin of which the weight ratio is 1 to 1 are creatively adopted as main active ingredients and matched with the sodium lignosulphonate, the high-dispersion silicic acid, the sodium dodecyl sulfonate and the kaolin with optimal use amounts. Experimental results show that the composition provided by the invention has the beneficial effects that the resistance of the hybrid liriodendron body embryo seedlings to adversetemperature environments of 4 DEG C low temperature and 40 DEG C high temperature is remarkably enhanced, and the drought resistance of the hybrid liriodendron body embryo seedlings can be obviously improved. The composition disclosed by the invention has the advantages of scientificity and reasonability in component matching, greenness, environmental protection, low toxicity and important practical application value.

Antibodies are used as biomarkers to assist in distinguishing gluten immune reactivity and sensitivity, silent celiac disease, Crohn's disease and other gut-related pathologies from classical celiac disease. In one class of embodiments, sera, saliva or other samples from a human or other animal are tested for antibodies to (a) a wheat antigen; (b) a gliadin antigen; and (c) one or more of a wheat germ agglutinin, a gluteomorphin, a glutenin, a deamidated glutenin, a prodynorphin, and a dynorphin. Test results are considered particularly interesting where the wheat antigen and the gliadin antigen are both selected from the group consisting of native and deamidated forms of α-gliadin 33-mer, α-gliadin-17-mer, γ-gliadin-15-mer, ω-gliadin-17-mer, and glutenin 21-mer. Test plates and kits can advantageously test for antibodies to at least three, five, seven or all of mixed wheat antigens, α-gliadin, γ-gliadin, ω-gliadin, glutenin, α-glutenin, wheat germ agglutinin, gluteomorphin, prodynorphins, transglutaminase-2, transglutaminase-3, transglutaminase-6, and gliadin-bound transglutaminase.
