Abstract
TNFα participates in a variety of physiological processes, but at supra-physiological concentrations it has been implicated in the pathology of inflammatory and autoimmune diseases. Therefore, much attention has been devoted to the development of strategies that overcome the effects of aberrant TNFα concentration. Promising strategies include drugs that destabilize the active (trimeric) form of TNFα and antagonists of TNFα receptor type I. Underpinning these strategies is the successful application of phage-display technology to identify anti-TNFα peptides and antibodies. Here, we review the development of inhibitors of the TNFα-TNF receptor system, with particular focus on the phage-display-assisted identification of molecules that interfere with this system by acting as inhibitors of TNFα or by sequestering TNFα away from its receptor.

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
OBJECTIVES To construct a phage display human antibody library (PDHAL) against pneumoconiosis for the diagnosis and treatment of coal worker pneumoconiosis (CWP). METHODS The PDHAL was established via CWP blood and six positive antibodies were discovered. 867 coal workers (558 CWP and 309 without CWP) and 393 controls were recruited to validate the results. RESULTS A PDHAL against CWP was established, from which six strong positive clones were selected, sequenced and identified as VEGF, interleukin-18, HSP70, HER3, Gz-B and RF. Logistic regression analysis revealed that VEGF (OR (95% CI), 0.02 (0.01to 0.07), P < 0.05), RF-Ab (OR (95% CI): 0.46 (0.28 to 0.73), P < 0.05) and HSP70/HSP-70-Ab (OR (95% CI): 0.71 (0.53 to 0.95), P < 0.05) were protective factors for CWP after adjustment of confounding factors. CONCLUSION The serum VEGF, RF-Ab and HSP-70/HSP-70 antibodies were potential biomarkers for diagnosis and treatment of CWP.

Abstract
PURPOSE Tumor necrosis factor alpha (TNF-α) is an inflammatory cytokine, involved in both physiological and pathological pathways. Because of central role of TNF-α in pathogenesis of inflammatory diseases, in the current study, we aimed to identify novel scFv antibodies against TNF-α using phage display technology. METHODS Using libraries composed of phagemid displaying scFv antibodies, four rounds of biopanning against TNF-α were carried out, which led to identification of scFvs capable of binding to TNF-α. The scFv antibody with appropriate binding affinity towards TNF-α, was amplified and used in ELISA experiment. RESULTS Titration of phage achieved from different rounds of biopanning showed an enrichment of specific anti-TNF-α phages during biopanning process. Using ELISA experiment, a binding constant (Kd) of 1.11 ± 0.32 nM was determined for the phage displaying J48 scFv antibody. CONCLUSION The findings in the current work revealed that the identified novel scFv antibody displayed at the N-terminal of minor coat proteins of phagemid binds TNF-α with suitable affinity. However, the soluble form of the antibody is needed to be produced and evaluated in more details regarding its binding properties to TNF-α.

RESULTS The J44 scFv antibody was cloned into the expression vector and successfully expressed and purified. The purity of the scFv fraction was confirmed using SDS-PAGE analysis. Western blotting technique was used to detect expression of 6×His tagged protein. CONCLUSION In the current study an anti-TNF-α scFv antibody was successfully expressed in bacterial expression system and purified on affinity column. The purified protein can be used in different in vitro and in vivo experiments in order to elucidate its functionality.

Abstract
Many approaches for generating large quantities of recombinant protein in Escherichia coli fuse the protein of interest to a protein tag to enhance solubility and improve recovery. However, the fusion tags can confound downstream applications, as the fusion partner can alter the structure and biological activity of the recombinant protein and proteolytic removal of the fusion tags can be expensive. Here we describe a new system for production of native proteins in E. coli that allows for removal of the fusion tag via intracellular self-cleavage by the human rhinovirus 3C (HRV3C) protease. This system allows for parallel cloning of target protein coding sequences into six different expression vectors, each with a different fusion partner tag to enhance solubility during induction. Temperature-regulated expression of the HRV3C protease allows for intracellular removal of the fusion tag following induction, and the liberated recombinant protein can be purified by affinity chromatography by virtue of a short six-histidine tag. This system will be an attractive approach for the expression and purification of recombinant proteins free of solubility-enhancing fusion tags, and should be amenable to high-throughput applications.

Abstract
BACKGROUND Fumonisin B1 (FB1 ) is a cancer-promoting mycotoxin produced by Fusarium species and one of the major food-borne toxins in corn and corn products. The objective of this study was to produce a single-chain variable fragment (scFv) antibody for determination of FB1 in corn samples. RESULTS Anti-FB1 monoclonal antibodies were obtained via the hybridoma technique. Specific heavy- and light-chain variable fragments were amplified with degenerate primers and constructed into scFv antibody fragments by splice overlap extension polymerase chain reaction with linker sequences. The resulting scFv DNA fragments were cloned into the phagemid pHEN1for selection and identification of functional scFv fragment by phage display. Prokaryotic expression vector pET22b-scFv was constructed to prepare anti-FB1 scFv antibody for establishment of indirect competitive ELISA. The detection capability (CCβ) of the scFv-based ELISA was 15.00 µg kg(-1), and the limit of detection was 8.32 µg kg(-1). The recoveries and coefficients of variation were 86.74-107.34% and 9.72-14.03%, respectively. In addition, the determined results of 30 naturally contaminated corn samples by the scFv-based ELISA are in agreement with the findings of high-performance liquid chromatography (R(2) = 0.97). CONCLUSION This scFv-based ELISA could be used as an efficient screening method for routine monitoring the residues FB1 in corn samples.

Abstract
Recombinant antibodies are highly specific detection probes in research, diagnostics, and have emerged over the last two decades as the fastest growing class of therapeutic proteins. Antibody generation has been dramatically accelerated by in vitro selection systems, particularly phage display. An increasing variety of recombinant production systems have been developed, ranging from Gram-negative and positive bacteria, yeasts and filamentous fungi, insect cell lines, mammalian cells to transgenic plants and animals. Currently, almost all therapeutic antibodies are still produced in mammalian cell lines in order to reduce the risk of immunogenicity due to altered, non-human glycosylation patterns. However, recent developments of glycosylation-engineered yeast, insect cell lines, and transgenic plants are promising to obtain antibodies with "human-like" post-translational modifications. Furthermore, smaller antibody fragments including bispecific antibodies without any glycosylation are successfully produced in bacteria and have advanced to clinical testing. The first therapeutic antibody products from a non-mammalian source can be expected in coming next years. In this review, we focus on current antibody production systems including their usability for different applications.
