The present application relates to a fusion protein and its application in detection of Helicobacter pylori CagA antibody, and belongs to the technical field of biology.The present application provides a fusion protein, wherein the fusion protein comprises a polypeptide with an amino acid sequence as shown in SEQ ID NO.1, or a derivative polypeptide with more than 80% homology with the amino acid sequence as shown in SEQ ID NO.1 and capable of being specifically combined with Helicobacter pylori CagA antibody; the fusion protein is capable of being specifically combined with Helicobacter pylori CagA antibody, and has a very high application prospect in detection of Helicobacter pylori CagA antibody.

There is provided, inter alia, an aqueous solution comprising (i) an antibody protein; and (ii) a antibody protein stabilizing mixture of arginine, methionine, and a C3 polyol.

The invention relates to application of a scavenger receptor A antibody in preparation of a medicine for inhibiting plasmodium transmission, and belongs to the technical field of malaria prevention and treatment. Aiming at the technical problem that in the prior art, the drug resistance of plasmodium to drugs and the resistance of mosquito vector to insecticides are increasingly serious, so that the malaria propagation control effect is reduced, the invention provides a scavenger receptor A antibody which is specifically combined with a scavenger receptor A on the surface of macrophage to inhibit the phagocytic function of the scavenger receptor A, so that the control effect of malaria propagation is improved. Therefore, the proliferation of antimalarial active bacteria (such as Elizabeth, shigella sonnei or klebsiella oxytoca) in the stomach of the anopheles is promoted, and the development of plasmodium in the midgut of the anopheles is indirectly blocked. The antibody can be used alone or in combination with a Pfs25 antibody. The anopheles infection rate and the number of oocysts are remarkably reduced (for example, the infection rate is reduced from 81.7% to 6%), an eco-friendly biological control mode which is not prone to drug resistance is provided, and a new strategy is provided for malaria transmission blocking.

The application discloses a foot-and-mouth disease virus type A ELISA antibody detection kit and a preparation method and application thereof. The application determines a sequence of a foot-and-mouth disease virus type A GH loop epitope polypeptide and a non-specific combination of a foot-and-mouth disease virus type O, effectively solves the non-specific combination problem through sequence reduction, obviously reduces the detection sensitivity of the type A antibody after the reduction, further improves the detection sensitivity through a form of a multi-antigen peptide to display the polypeptide sequence. Finally, the polypeptide epitope combination, the antigen coated plate containing the polypeptide epitope combination and the ELISA antibody detection kit are determined. The total coincidence rate of the kit for detecting foot-and-mouth disease inactivated vaccine immune antibodies and negative serum is as high as 95% or more, but the positive detection rate of the kit for detecting foot-and-mouth disease synthetic peptide vaccine immune antibodies is obviously improved, and the cross reaction of the kit for detecting foot-and-mouth disease virus type O vaccine and pig foot-and-mouth disease virus type O inactivated vaccine immune antibodies is effectively reduced.

The invention discloses a Napsin A biological fusion enzyme antibody with a signal protein tag and application, an amino acid sequence of a light chain variable region of an anti-human Napsin A antibody is shown as SEQ ID NO: 7, an amino acid sequence of a heavy chain variable region of the anti-human Napsin A antibody is shown as SEQ ID NO: 3, the signal protein tag HRP is inserted into the N end of a light chain of the anti-human Napsin A antibody, and the amino acid sequence of the light chain variable region of the obtained HRP-Napsin A antibody is shown as SEQ ID NO: 5. In addition, the invention also provides a preparation method of the HRP-Napsin A antibody, the HRP-Napsin A antibody is a molecule completely secreted along with the antibody, has no heterogeneity, is good in sensitivity, high in specificity and stable in performance, and does not need to add a secondary antibody during detection, so that the cost is saved, and the efficiency is improved.
