U-READ: Unit for Rapid Engineered Antibody Development
Isolation of antibodies
The continuous demand from basic and applied research is increasing the need for isolating antibodies with desired properties in more efficient manners. Recombinant antibody technologies combined with in vitro display methods, such as phage display, offers a great alternative to traditional immunization techniques. Not only does it provide a renewable monoclonal source of antibodies, the process generates characterized antibody fragments in approximately three to four weeks compared to months with immunizations. Phage display technology allows control over the selection processes to a higher degree than what is possible with immunizations. Also, since the system allows the DNA encoding the antibody fragments to be easily manipulated, fine-tuning of affinity and specificity can easily be done. In addition, since all the steps of the selection and screening process are liquid based they can be automated.
High-throughput phage selection
At the department we have set-up a high-throughput phage selection and screening pipeline that allows us to generate binders to a large number of antigens in a short time frame. This pipeline was originally scaled-up as part of AFFINOMICS, an EC FP7 Collaborative Project.
The Unit is able to select specific antibodies from large in-house developed antibody libraries using phage display technology. As proof of principle, generated antibodies are used in-house in a variety of research applications, for instance in our various affinity proteomics platforms.
Analysis
The U-READ platform has access to analytical instrumentation of great value in studies of molecular interactions and molecular cell binding properties. We host a Biacore X1+ instrument for assessment of interaction kinetics using surface plasmon resonance technology. We also host a flow cytometry instrument (iQue Plus) for studies of cells and cell binding properties at high throughput. We are also closely connected to the Department of Immunotechnology's regular flow cytometry unit that hosts a multi-color spectral flow cytometer and cell sorter.
National engagement
The unit is integrated as a Display and Selection Technologies Unit into SciLifeLab's Drug Discovery and Development platform. This National Facility supports the development of therapeutic antibodies to targets as suggested by the partner primary investigators.
International engagement
The U-READ platform is engaged within the international Adaptive Immune Repertoire Community's effort to generate resources for and advocate for better practice in and understanding of immunoglobulin and T cell receptor gene annotation and analysis, to promote high research of repertoires och cells and molecules that make up adaptive immunity. In this efforts we collaborate directly with one of the nomenclature sub-committees within the International Union of Immunological Societies.

Technical platforms
The unit uses its in-house developed antibody fragment (scFv) library for selection of specific antibodies using phage display technology. We host a variety of technology platforms such as:
- Hamilton robot for efficient liquid handling
- King Fisher robot for efficient, parallell phage display selection procedures a variety of immunoassay platforms including ELISA, Luminex etc.
- Biacore 1X+ surface plasmon resonance-based real time high through-put interaction assessment platform
- iQue Plus high content, high throughput flow cytometry assay platform for analysis of protein binding to cells and particles.
The Department also hosts a variety of other technology platforms including flow cytometry (analyzer as well as spectral cell sorter), qPCT, GeoMx Digital Spatial Profiler, nanostring nCounter analysis system, et cetera.
