Improving the Specificity of an Anti-Estradiol Antibody by Random Mutagenesis and Phage Display

Estradiol is a steroid hormone secreted by endocrine glands (ovary, testis) [3]. The variation of estradiol levels in blood or urine may be associated with many pathologies such as hormone-dependent cancers and diseases of sexual behaviour [5]. Measurements of the concentration of estradiol in blood or urine is of great importance both for clinical diagnosis and during therapy. Competitive immu...

An improved phage-display panning method to produce an HM-1 killer toxin anti-idiotypic antibody

BACKGROUND Phage-display panning is an integral part of biomedical research. Regular panning methods are sometimes complicated by inefficient detachment of the captured phages from the antigen-coated solid supports, which prompted us to modify. Here, we produce an efficient antigen-specific single chain fragment variable (scFv) antibody by using a target-related molecule that favored selection ...

Antibody phage display: technique and applications.

inTrOducTiOn The production of human monoclonal mAbs for research and clinical use is closely related to the development of phage display technology, initially described by Smith in 1985 and further developed by other groups (e.g., Winter, McCafferty, Lerner, Barbas). Antibody phage display (APD) is based on genetic engineering of bacteriophages (viruses that infect bacteria) and repeated round...

Antibody engineering and phage display technology

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...
