Dr. Andrew Hayhurst's laboratory has a variety of interests mostly related to antibody engineering technology, applications to emerging pathogen countermeasures, tumor targeting and nanotechnology. 

We have recently developed an antibody pipeline that enables selection, screening and assembly of stop-gap assays to native pathogens and toxins within days.  We prefer llama single domain antibodies (sdAb) over other antibody formats owing to their high production levels, modularity and ruggedness (a).  Our method bypasses protein purification for assembling a stop gap assay via the facile step-wise occlusion of biotin (b) and is plug-and-play within any display platform including a novel cell/vector combination built to enable both low and high level sdAb expression for display and production respectively (c).  

Our anti-Filoviral llama sdAb clones appear to outperform our competitors shark sdAb clones showing higher cross-reactivities among the Ebola group (d) and we are rationalizing why the C-terminal domains of Ebolavirus and Marburgvirus nucleoprotein provide such an attractive target for the sdAb formats.
