Abstract

The overall objective is the design and production of a protein reagent for detection, preparation and purification of Fab and Fv fragments. Bacterial protein L (SpL) binds only to V kappa domains, and our aim is to modify its binding properties by mutagenesis to encompass V lambda, and to allow for elution of bound Ig fragments under mild conditions by modifying the pH dependence of binding. We have cloned and expressed SpL in E. coli and determined its crystal structure, and will crystallise complexes with Fab and Fv for X-ray analysis. Random mutagenesis by phage display will be performed, and mutants assayed by ELISA, fluorescence and BIAcore SPR.
