Abstract: The present disclosure relates to an antibody specifically binding to bovine pregnancy-associated glycoprotein 1 (bPAG1) or an antigen-binding fragment thereof. The present disclosure further relates to a hybridoma cell producing the antibody; a composition including the antibody as an effective ingredient for diagnosis of bovine pregnancy; and a kit for diagnosis of bovine pregnancy. The present disclosure also relates to a method of diagnosing bovine pregnancy. Binding specifically to bPAG1, which is a pregnancy-associated plasma protein in bovines, the antibody allows a simple diagnosis of pregnancy in animals such as bovines of which the reproduction is important, so that the antibody may be usefully applied in the livestock industry by increasing reproduction efficiency.

Abstract: Provided are a peptide consisting of an amino acid sequence of SEQ ID NO: 3, which is a novel epitope of immunoglobulin E (IgE), and an anti-IgE antibody binding to the peptide, in which the peptide and the antibody may be applied for diagnosing an allergic disease or research on a therapeutic agent therefor. In addition, provided are a kit for analyzing IgE in a sample containing the antibody and a method of diagnosing an allergic disease using the kit, which may perform qualitative analysis to determine the presence or absence of a typical inhalant and food allergies with high incidence in Koreans, and diagnose an allergy within a short period after blood collection.
