The transgenic plants expressing one or more antagonist IL-10R peptides and anti-IL-10 single domain antibodies that stimulate or modulate the immune system and improve gastrointestinal physiology of an animal fed the transgenic plants or tissues thereof and the genes encoding the antagonist IL-10R peptides and anti-IL-10 single domain antibodies are described. The animal feed additives and animal feed incorporating the transgenic plants or tissues thereof are also described. Methods of stimulating or modulating an animal's immune system, improving an animal's gastrointestinal physiology, improving animal performance by using the transgenic plants or tissues thereof, and treating animals infected with a gastrointestinal pathogen are provided.

A method for detecting MERS-CoV at high sensitivity and specificity using IgY antibodies that bind to MERS-CoV N protein, its fragments and domains. Isolated or purified IgY monospecific antibodies to MERS-CoV N protein.

The present invention relates to a monoclonal antibody which specifically binds to an EGF2 domain of colon cancer secreted protein-2 (CCSP-2), or an antigen-binding fragment thereof. The monoclonal antibody or the antigen-binding fragment thereof of the present invention specifically binds to the EGF2 domain of CCSP-2, and thus has significantly increased affinity compared with existing peptides specifically binding to CCSP-2 and further increased specificity compared with existing antibodies to CCSP-2. Therefore, in future, accurate diagnosis can be achieved by specific detection of CCSP-2 in the protein level.

A method for detecting MERS-CoV at high sensitivity and specificity using IgY antibodies that bind to MERS-CoV N protein, its fragments and domains. Isolated or purified IgY monospecific antibodies to MERS-CoV N protein.

A binding domain or a multimer or a variant thereof which comprises a variable region encoded by a nucleic acid based on, derived or obtained from an animal phylogenetically distal from a human, which variable region is paired with a human variable region.

The present invention provides compositions, kits, and methods for the detection of host cell proteins (HCPs) in biological samples. In some embodiments, the present invention utilizes immunization of aves hosts with proteins derived from non-aves host cells to produce aves antibodies specific for non-aves HCPs.

The present disclosure provides a composition and a method both for improving the hair. In one embodiment, the hair is improved using an antibody. In one embodiment, the antibody is produced using a bacterium occurring on the scalp or a hair root as an immunogen. In one aspect, the present invention also provides a method for improving the hair in a subject, including the step of administering an antibody produced using a microorganism-derived substance as an immunogen to the subject. The antibody according to the present invention may be administered in the form of a composition. According to the present invention, the promotion of hair growth or the prevention of hair loss can be achieved.

Disclosed are the development of a recombinant chicken IgY monoclonal antibody and a recombinant chicken IgY single-chain variable fragment (scFv) antibody raised against human thymidine kinase 1 in mammalian cells and a preparation method and use thereof. A light chain of the scFv antibody includes an amino acid sequence shown in SEQ ID NO: 1, and a heavy chain of the scFv antibody includes an amino acid sequence shown in SEQ ID NO: 2.

Methods and compositions are provided for rapid preparation of anti-SARS-CoV-2 protein polyclonal IgY antibodies. Compositions comprising the antibodies are useful for decreasing transmission, duration, and/or severity of coronavirus disease 2019 (COVID-19). Lingual and sublingual alimentary traps, oral, parenteral, and inhalable compositions are provided for preventing and treating COVID-19. The compositions can be rapidly tailored for seasonal or even monthly mutations in the SARS-CoV-2 viral antigenic proteins. Improved methods of generating IgY antibodies are also provided.
