Background: Antibody phage display is highly dependent on the availability of antibody libraries. There are several forms of libraries depending mainly on the origin of the source materials. There are three major classes of libraries, mainly the naïve, immune and synthetic libraries. Methods: Immune antibody libraries are designed to isolate specific and high affinity antibodies against disease antigens. The pre-exposure of the Read More

The selection process aims sequential enrichment of phage antibody display library in clones that recognize the target of interest or antigen as the library undergoes successive rounds of selection. In this review, selection methods most commonly used for phage display antibody libraries have been comprehensively described.

Background: The discovery of functional heavy chain-only antibodies devoid of light chains in sera of camelids and sharks in the early nineties provided access to the generation of minimal-sized, single-domain, in vivo affinity-matured, recombinant antigenbinding fragments, also known as Nanobodies. Methods: Recombinant DNA technology and adaptation of phage display vectors form the basis to construct large naïve, sy Read More

Phage display technology has revolutionized the science of drug discovery by transforming the generation and manipulation of ligands, such as antibody fragments, enzymes, and peptides. The basis of this technology is the expression of recombinant proteins or peptides fused to a phage coat protein, and subsequent isolation of ligands based on a variety of catalytic, physicochemical/binding kinetic and/or biological charac Read More

Background: The complex multi-chain architecture of antibodies has spurred interest in smaller derivatives that retain specificity but can be more easily produced in bacteria. Domain antibodies consisting of single variable domains are the smallest antibody fragments and have been shown to possess enhanced ability to target epitopes that are difficult to access using multidomain antibodies. However, in contrast to natural ca Read More

Background: Antibody phage display is a major technological platform for the generation of fully human antibodies for therapeutic purposes. The in vitro binder selection by phage display allows researchers to have more extensive control over binding parameters and facilitates the isolation of clinical candidate antibodies with desired binding and/or functional profiles. Methods: Since the invention of antibody phage display in lat Read More

Background: The identification of combinatorial antibodies against many different targets in oncology, autoimmune, inflammatory and infectious diseases has uncovered novel strategies to control and prevent diseases’ onset and progression, and represents the fastest growing market for the pharmaceutical industry. Phage Display has been successfully used in the identification of unknown targets, which combines shotgun ap Read More

Infectious diseases in the skin represent a major group of pathologies that contribute annually for significant health economic expenses. According to WHO, Buruli Ulcer (BU) and Cutaneous Leishmaniasis (CL) are two neglected tropical diseases for which therapy remains inadequate. Topical delivery of therapeutics constitutes an advantageous alternative to treat infected skin lesions as it allows a direct treatment of affected Read More

Suramab (SUM) is a new pharmaceutical combination made up of suramine (SUR) and bevacizumab (BVM), which showed a high synergistic effect when administered jointly. As the pharmaceutical vehicle, poloxamer aqueous dispersions were used since this system is able to maintain their fluidity at low temperatures (<15ºC) but which become gel in the corporal environment (>35ºC). In the present study we aimed at evalu Read More
