Bio-Diagnostics has grown over the years and now has three core areas of specialty. Each of these divisions are all developed from our expertise in Immunology. Bio-Diagnostics has been a leading UK manufacturer and supplier of innovative diagnostics since November 1979, and continue to focus and grow its interests in Autoimmunity, Immunohistochemistry, and Dermatology, which includes allergy testing.



At the end of 2009 Bio-Diagnostics were appointed the exclusive UK distributor for DB Biotech (; a company founded in 2006 which has since developed high quality antibodies used in research and routine clinical diagnostics within histopathology.

DB Biotech is focused on the design and production of high quality rabbit monoclonal primary antibodies developed by a novel in vitro cloning technology which is the original invention of the company. With their scientific expertise they are introducing a new level of quality of monospecific clonal antibodies characterized by an exceptional specificity, affinity and avidity. The unique in-vitro cloning technology enables the preparation of a pure immunoglobulin fraction corresponding to a single clone of B lymphocytes. The obtained immunoglobulin recognizes only one single linear epitope on the antigen molecule, making a DB Biotech antibody comparable in quality to its monoclonal analogue.

In addition, the influence of the protein tertiary structure – frequently present in epitopes formed during production of monoclonal antibodies – is eliminated in the immunoglobulin’s corresponding to the clonal antibody. DB Biotech produced antibodies correspond strictly to the conserved linear epitope of the antigen molecule, yielding a higher-quality, more specific antibody with significantly better affinity and avidity. DB have an international reputation for the development of high quality antibodies used in research and routine clinical diagnostics. DB Biotech‘s goal is to establish a new gold-standard for the development and application of antibodies on a daily basis, from background-free western blots, to special quantitative diagnostics, and potential applications of humanized antibodies for disease treatment purposes.

Bio-Diagnostics IHC division continues to grow, with new antibodies added to the range regularly based on welcomed feedback from international distributors and UK customers. These antibodies are now being increasingly adopted with mounting success as more and more customers experience the outstandingly high quality of our IHC product range. Bio-Diagnostics are committed to provide outstanding quality and are pleased to endorse the DB Biotech range within its brand, all at prudent pricing to help support our customers budgetary constraints. Having already brought p16, C4d and p63 monoclonal primary antibodies firmly into the UK market, newer products such as Racemase will again extend a rapidly establishing new group of monoclonal primary antibodies to develop the choice to UK laboratories for many years to come.
