About Us

Hello, and thank you for visiting our website.

Here at Cytomark (a division of Caltag Medsystems Ltd.), we are dedicated to the development of cell stabilisation reagents for use in flow cytometry. Based in Buckingham, we manufacture TransFix®, TransFix-related products and Blood Controls for scientists all over the world. We are committed to helping organisations reduce the pressure associated with the analysis of fresh samples, and also provide quality assurance that their equipment and sample processing procedures are performing optimally.

Our customer service team and technical specialists offer comprehensive support and look forward to working with you.

Our History

TransFix® was developed by medical scientists from UK NEQAS out of the requirement to produce stabilised blood samples that could be used in External Quality Assurance programs for flow cytometry.

TransFix® has been in circulation amongst the research world since 1999. In 2005, the NHS licensed TransFix® to Cytomark, making it readily available to the clinical and scientific world.

The launch of Cytomark coincided with Caltag Medsystems (the parent company of Cytomark) relocating to occupy facilities in Botolph Claydon, Buckinghamshire, gaining access to GMP laboratories.

In 2009, after outgrowing the facilities in Botolph Claydon, we relocated to the Whiteleaf Business Centre in Buckingham. Our facilities here include manufacturing and product development laboratories with an increased capacity to further develop and manufacture cell stabilisation products such as TransFix®.

TransFix®

TransFix® is a CE marked solution for IVD use that prevents cellular degradation in human peripheral blood for analytical testing purposes. Leucocytes and leucocytic antigens are stabilised for up to 14 days at sample storage temperatures between 2-8°C, and for 4 days at temperatures between 25-37°C . TransFix® is also used to stabilise CSF and bone marrow prior to flow cytometric analysis. As a result, samples treated with TransFix® can be analysed at a more convenient time for the operator.

For a list of countries where TransFix® is registered as an IVD product, please click here.

Our products are widely used in hospitals, reference laboratories, academic research institutions, pharmaceutical and biotechnology companies, and government agencies.

Blood Controls

The ISO standard entitled 'ISO 15189: Medical laboratories - Particular requirements for quality and competence', refers to the requirement for reference samples during flow cytometer set up and running. Our Stabilised Human Whole Blood and CD4 Low and Normal Controls provide suitable reference samples for this purpose. The stabilisation process is robust, resulting in controls that are stable for up to 90 days from the date of manufacture when stored at 2 - 8°C, and have an open vial stability of 1 month.

Please contact us for further information.
