In this review, single-chain fragment variable construction using phage-display technology as a promising anticancer immunotherapy technology is described. Cloning and the specific bio-panning selection with phage display technology, as well as the use of the epidermal growth factor receptor (EGFR) at the surface of MCF-7 cells as the antigen for the straightforward specific selection of single...

Bacteriophage lambda (lambda) permits the display of many foreign peptides and proteins on the gpD major coat protein. However, some recombinant derivatives of gpD are incompatible with the assembly of stable phage particles. This presents a limitation to current lambda display systems. Here we describe a novel, plasmid-based expression system in which gpD deficient lambda lysogens can be co-co...

Antibodies are an essential biotechnological tool being a part of immunodiagnostics, therapeutics and life science research instruments. Due to the advances of molecular biology methods, it became possible to manipulate structure and properties of antigen-binding domains of antibodies (1). This led to the creation of a variety of small-sized, single-domain, bi-specific, conjugated antibodies, a...

The expression of exogenous peptides on the surface of filamentous bacteriophage was initially described by Smith in 1985. Since his first study, different molecules such as small peptides and antibodies have been displayed on coat proteins of phage, greatly expanding the applications of the technology. The past decade has seen considerable progress in the techniques and applications of phage l...

Using simple design and selective pressure, we have evolved an artificial M13 bacteriophage coat protein. M13 coat proteins first reside in the bacterial inner membrane and subsequently surround the DNA core of the assembled virus. The artificial coat protein (ACP) was designed and evolved to mimic both functions of the natural M13 coat proteins, but with an inverted orientation. ACP is a non-f...

We describe the isolation of a CCR5-specific antibody, ST6, from an antibody phage display library generated from an immune rabbit. ST6 was previously shown to efficiently prevent the surface expression of CCR5 when expressed intracellularly (Steinberger, P., Andris-Widhopf, J., Buhler, B., Torbett, B. E., and Barbas, C. F., III (2000) Proc. Natl. Acad. Sci. U. S. A. 97, 805-810). Because ST6 h...

OBJECTIVE To construct an immune alpaca phage display library, in order to obtain a single domain anti-BAFF (B cell-activating factor) antibody. METHODS Using phage display technology, we constructed an immune alpaca phage display library, selected anti-BAFF single domain antibodies (sdAbs), cloned three anti-BAFF single-domain antibody genes into expression vector pSJF2, and expressed them e...

Phage display, SELEX and other methods of combinatorial chemistry have become very popular means of finding ligands with high affinities to given targets. Despite their success, they suffer from numerous sources of error and bias, such as very low initial concentrations of species, non-specific binding, and the sampling of only a tiny fraction of the library at the end of an experiment. To unde...

Phage display is a technique that involves the coupling of phenotype to genotype in a selectable format. It has been extensively used in molecular biology to study protein-protein interactions, receptor and antibody binding sites, and immune responses; to modify protein properties; and to select antibodies against a wide range of different antigens. In the format most often used, a polypeptide ...

Protein-protein interactions mediate essentially all biological processes. A detailed understanding of these interactions is thus a major goal of modern biological chemistry. In recent years, genome sequencing efforts have revealed tens of thousands of novel genes, but the benefits of genome sequences will only be realized if these data can be translated to the level of protein function. While ...
