A strategy for mapping and neutralizing conformational immunogenic sites on protein therapeutics.

Antibodies are highly specific recognition molecules which are increasingly being applied to target therapy in patients. One type of developmental antibody-based therapy is antibody directed enzyme prodrug therapy (ADEPT) for the treatment of cancer. In ADEPT, an antibody specific to a tumor marker protein delivers a drug-activating enzyme to the cancer.

WAM: an improved algorithm for modelling antibodies on the WEB.

An improved antibody modelling algorithm has been developed which incorporates significant improvements to the earlier versions developed by Martin et al. (1989, 1991), Pedersen et al. (1992) and Rees et al.

Guided selection of a pan carcinoma specific antibody reveals similar binding characteristics yet structural divergence between the original murine antibody and its human equivalent.

Antibody engineering provides an excellent tool for the generation of human immunotherapeutics for the targeted treatment of solid tumours. We have engineered and selected a completely human antibody to epithelial glycoprotein-2 (EGP-2), a transmembrane glycoprotein present on virtually all human simple epithelia and abundantly expressed on a variety of human carcinomas. We chose to use the procedure of "guided selection" to rebuild a high-affinity murine antibody into a human antibody, using two consecutive rounds of variable domain shuffling and phage library selection.
