Abstract
Phage display is one of the important and effective molecular biology techniques and has remained indispensable for research community since its discovery in the year 1985. As a large number of nucleotide fragments may be cloned into the phage genome, a phage library may harbour millions or sometimes billions of unique and distinctive displayed peptide ligands. The ligand–receptor interactions forming the basis of phage display have been well utilized in epitope mapping and antigen presentation on the surface of bacteriophages for screening novel vaccine candidates by using affinity selection-based strategy called biopanning. This versatile technique has been modified tremendously over last three decades, leading to generation of different platforms for combinatorial peptide display. The translation of new diagnostic tools thus developed has been used in situations arising due to pathogenic microbes, including bacteria and deadly viruses, such as Zika, Ebola, Hendra, Nipah, Hanta, MERS and SARS. In the current situation of pandemic of Coronavirus disease (COVID-19), a search for neutralizing antibodies is motivating the researchers to find therapeutic candidates against novel SARS-CoV-2. As phage display is an important technique for antibody selection, this review presents a concise summary of the very recent applications of phage display technique with a special reference to progress in diagnostics and therapeutics for coronavirus diseases. Hopefully, this technique can complement studies on host–pathogen interactions and assist novel strategies of drug discovery for coronaviruses.

Abstract
Agkistrodon acutus bites are conventionally treated with animal-derived antivenom, the use of which is limited due to allergic reactions and serum sickness. Thus in the present study, the genes of humanized antibodies produced in response to A. acutus venom were extracted from lymphocytes from patients bitten by A. acutus. A single-chain variable fragment (scFv) library against venom was constructed using a T7 phage display system. ScFv genes that exhibited high affinity to venom were selected by library biopanning. An expression system was constructed for antivenom scFv fused with 6×His tag at its N- and C-terminus using pET-28a (+) vector. The scFv proteins could achieve functional and soluble expression in Escherichia coli via the auto-induction method. The purity and activity of the scFv genes and proteins were confirmed by SDS-PAGE, western blotting and ELISA. The results indicated that three soluble scFv proteins exhibited specific affinity to A. acutus venom and were harvested via the auto-induction method.

Abstract
The production of recombinant antibodies has had a tremendous impact on several research fields, most prominently in biotechnology, immunology and medicine, enabling enormous advances in each. Thus far, a broad diversity of recombinant antibody (rAb) forms have been designed and expressed using different expression systems. Even though the majority of rAbs approved for clinical use are targeted to humans, advances in veterinary medicine seem promising. The aim of this mini-review is to present an update regarding the rAbs in veterinary medicine reported to date, as well as their potential use in diagnostics, prophylaxis and therapeutics. Full- and single-chain fragment variables are the most common forms of rAbs developed for the detection, prevention and control of parasitic, bacterial and viral diseases, as well as pain and cancer treatment. Nonetheless, advances in research seem to be skewed toward economically important animals, such as pigs, cows, poultry and dogs. Although significant results have been obtained from the rAbs reported here, most have not been developed enough to be approved. Further research and clinical trials should be encouraged to enable important findings to fulfill their intended potential to improve animal well-being.

Abstract
The analysis of secreted antibody from large and diverse populations of B cells in parallel at the clonal level can reveal desirable antibodies for diagnostic or therapeutic applications. By immobilizing B cells in microdroplets with particulate reporters, decoding and isolating them in a microscopy environment, we have recovered panels of antibodies with rare attributes to therapeutically relevant targets. The ability to screen up to 100 million cells in a single experiment can be fully leveraged by accessing primary B-cell populations from evolutionarily divergent species such as chickens.

Abstract
Female, 8-week-old BALB/c mice were immunized with the progesterone complete antigen (P4-BSA). Two monoclonal antibodies (MAbs) against P4, named 8G6 and 11A11, were obtained by the lymphocyte hybridoma technique. The titers of the cell culture supernatant and ascitic fluid of MAb 8G6 were 1: 16,000 and 1:512,000, respectively, and the titers of the cell culture supernatant and ascitic fluid of MAb 11A11 were 1: 8000 and 1:256,000, respectively. The subtypes of the MAbs 8G6 and 11A11 were IgMκ. In specific analysis, both of the two MAbs did not react with estradiol. These data demonstrated that the MAbs 8G6 and 11A11 have a potential use for developing diagnostic reagents of progesterone.

Abstract
Recent outbreaks of porcine epidemic diarrhea virus (PEDV) have caused widespread concern. The identification of proteins associated with PEDV infection might provide insight into PEDV pathogenesis and facilitate the development of novel antiviral strategies. We analyzed the differential protein profile of PEDV-infected Vero E6 cells using mass spectrometry and an isobaric tag for relative and absolute quantification. A total of 126 proteins were identified that were differentially expressed between the PEDV-infected and mock-infected groups (P<0.05, quantitative ratio ≥1.2), among which the expression of 58 proteins was up-regulated and that of 68 proteins was down-regulated in the PEDV-infected Vero E6 cells, involving in integrin β2/β3, cystatin-C. The Gene Ontology analysis indicated that the molecular function of the differentially expressed proteins (DEPs) was primarily related to binding and catalytic activity, and that the biological functions in which the DEPs are involved included metabolism, organismal systems, cellular processes, genetic information processing, environmental information processing, and diseases. Among the disease-related functions, certain anti-viral pathways and proteins, such as the RIG-I-like receptor, Rap1, autophagy, mitogen-activated protein kinase, PI3K-Akt and Jak-STAT signaling pathways, and integrin β2/β3 and cystatin-C proteins, represented potential factors in PEDV infection. Our findings provide valuable insight into PEDV-Vero E6 cell interactions.

Abstract
Female, 8-week-old BALB/c mice were immunized with purified recombinant proteins of the predicted immunodominant region of bovine haptoglobin (pirBoHp). Two monoclonal antibodies (MAbs), named 1B3 and 6D6, were prepared by conventional B lymphocyte hybridoma technique. Titers of ascitic fluid and cell culture supernatant of MAb 1B3 were 1:9.6 × 10(8) and 1:8.2 × 10(4), respectively, and that of MAb 6D6 were 1:4.4 × 10(5) and 1:1.0 × 10(4), respectively. The subtype of MAbs 1B3 and 6D6 was IgG1κ. In Western blot analysis, MAbs 1B3 and 6D6 could recognize the α-chain of native BoHp from plasma of dairy cows. These data indicated that MAbs 1B3 and 6D6 have a potential use for developing diagnostic reagents of BoHp.

Abstract
The purified C subunit of the recombinant porcine aminopeptidase N (rpAPN-C) protein was used as an immobilized target to screen potential ligands against rpAPN-C from a 12-mer phage display random peptide library. After five rounds of biopanning, five phage clones showed specific binding affinities to rpAPN-C. In 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyl tetrazolium bromide (MTT) assays, the phage clone PM1, which contained the HDAISWTHYHPW peptide sequence, had a protective effect against TGEV infection in swine testis cells. Therefore, the HDAISWTHYHPW peptide sequence has a potential use as a small molecular therapeutic agent against TGEV infection.

Abstract
The variable regions of the heavy chain (VH) and light chain (VL) were amplified by RT-PCR from the hybridoma 6E6, which secretes the monoclonal antibody against PEDV S protein. The VL and VH amplicons were combined using SOE-PCR by a 12 amino acid flexible linker (SSGGGGSGGGGS), which produced the scFv gene (named scFv/6E6). After sequence analysis, the scFv/6E6 gene was cloned into the prokaryotic expression vector pGEX-6p-1 with a GST-tag. The recombinant scFv/6E6 protein was successfully expressed in recombinant Escherichia coli by IPTG induction. Moreover, the recombinant scFv/6E6 protein was purified from the inclusion body form by the gel-cutting measure followed by electroelution and dialysis. The recombinant scFv/6E6 protein reported here will provide some basis for further antiviral drug research based on the scFv molecule.
