The Company
ISO 13485:2016
Based in Newcastle upon Tyne, HistoCyte Laboratories Ltd is certified to the EN ISO 13485:2016 standard. We have been able to work closely with academic scientists and pathologists in order to test our product range and engage with experts in the histopathology field. This, together with the relationships we have developed with other key opinion leaders and institutions, has allowed us to clearly identify the needs of scientists. As a result, we aim to deliver high quality, reproducible and cost-effective analyte control material for same-slide use in histopathology. Our current products include controls for PD-L1, Her2, ER, PR, EML4-ALK, ROS1, NPM-ALK, HPV and p16, with many more in development. The products are available in a range of formats to suit the individual workflow and requirements of each laboratory.
The Products
Each product is available as pre-cut slides or as full blocks of cell micro-arrays. They contain 2mm diameter cores that are between 3mm and 3.5mm in length. Appropriate cell lines are selected that deliver the required range of expression for any given biomarker. This can be as simple as a positive and negative to prove reagents have been applied to the slide correctly, or as complex as a full range of expression to demonstrate assay sensitivity. The cell lines are processed in-house using our proprietary methods that allows for the creation of a very high density cell block with cells that retain their morphology. Most importantly, the process is cost-effective so we are able to deliver the products to the customer at a fraction of the cost of conventional control material.

All of our products are validated with standardised assays where available and are assessed in field by a wide number of laboratories so you can trust that the results are consistently reproducible in your laboratory. To view a full list of our products, head over to the products page. Alternatively, if you wish to find out more about our product pipeline, then please contact us.

The Aim
It is recognised that the identification of suitable archive tissue for use as controls in slide based assays can be difficult due to heterogeneous expression of biomarkers, fixation artefacts, rarity of their expression, or just general lack of availability. Currently, some laboratories run single batch controls per staining run. However, most fully automated staining platforms treat each slide in an individual fashion and therefore the use of single slide controls is best practice as it reflects what has happened to each individual slide. The requirement for single slide controls compounds the issue of suitable control tissue availability.

The novel technology developed by HistoCyte Laboratories Ltd employs cell lines to avoid these issues and allows us to process the cell lines in to tissue-like controls. These controls also have the advantage of being manufactured to a reproducible standard and with inexhaustible supply. Our aim is to deliver this cost-effective control material to laboratories looking to improve confidence in their results and ultimately the service they offer. We will continue to expand our product range to include additional biomarkers, working closely with key opinion leaders in industry and academia to develop control material that is relevant and that provides confidence where it is most needed.

The History
The founders, Dr Ian Milton and Colin Tristram, share over 30 years of experience in the development of diagnostic products, including cell line controls for use in diagnostic assays. As a result, we understand the requirements of the market and are manufacturing products that we know can make a positive difference in laboratories across the world.

Colin brings to HistoCyte Laboratories Ltd a wealth of commercial and clinical knowledge given his experience and connections within the IVD field from the last fifteen years. Colin studied Medical Microbiology at the University of Newcastle upon Tyne with a specific interest in immunology. He subsequently joined the expanding R&D hybridoma team at Novocastra Laboratories Ltd as a Research Associate helping to develop the range of monoclonal antibodies. As part of Colin’s MSc he studied Her2 in breast cancer and breast cancer cell lines looking at differences in expression of internal and external domains. As a consequence of this work he developed in-house procedures for the processing of formalin fixed paraffin embedded cell lines used as immunohistochemical controls. These were subsequently adopted by various laboratory External Quality Assurance Schemes, namely The UK National External Quality Assurance Scheme for Immunocytochemisty and In-situ hybridisation (UKNEQAS-ICC & ISH).

Following the acquisition of Novocastra Laboratories Ltd by Vision BioSystems Ltd, Colin joined the commercial team expanding the sales of monoclonal antibodies and the Bond automated IHC/ISH platform throughout the UK, Europe and USA. As a consequence Colin developed a wide network of pathologists and researchers in many of the top hospitals and institutes enabling him to develop a Key Opinion Leader program and company publication reAGENTS.

After the acquisition of Vision Biosystems Ltd by the Danaher corporation Colin created the Innovation department at the Newcastle Leica Biosystems facility. The department was responsible for the qualification of projects from a clinical and commercial perspective prior to any R&D work. Over this period there was the development of class I and class III devices and wider collaborations with academics, clinicians and other companies within the biotech industry. Colin was instrumental in developing an Ideation process that worked for an IVD development work stream within the Danaher Business Systems Accelerated Development Process (APD).

As well as being a member of the Pathology Society of Great Britain and Ireland, Colin has previously been an assessor for UKNEQAS. Additionally, since 2010 Colin has been a Consultant and Guest Lecturer for the University of Newcastle upon Tyne at the Graduate School, Faculty of Medicine.

  • Publications
As Technical Director of HistoCyte Laboratories Ltd, Dr Milton provides a strong scientific background. Dr Milton gained his PhD at the University of Newcastle upon Tyne and began his career in the development of monoclonal antibodies in a University spin-out company called Novocastra Laboratories Ltd over 20 years ago. This was the origin of his experience in biotechnology research and development. Over this period Dr Milton became involved in both general management and R&D management. Specifically he has gained detailed experience in the implementation and management of control systems for the design and manufacture of in vitro diagnostic products.

Dr Milton has extensive experience in guiding fast growing organizations through post-acquisition cultural change and the transition from private to public ownership. In 2002, Novocastra was acquired by an Australian company, Vision BioSystems Ltd. This resulted in considerable change and growth for the Novocastra facility now called Vision BioSystems Newcastle Ltd. Subsequently in 2007 Vision BioSystems Ltd was acquired by the Danaher Corporation and incorporated into Leica Microsystems to create the Biosystems Division Leica Biosystems Newcastle Ltd.

Each acquisition was with a back drop of great regulatory change in the EU, USA and China. This provided Dr Milton with experience in the implementation of changes required to transform the company to comply with ISO design and manufacturing standards and conformity to FDA and SFDA standards and subsequent release of IVD labeled products.
