A Cellular Antigen Stabilisation Reagent TransFix® is a stabilisation reagent that preserves cellular surface antigens and prevents cellular degradation in a variety of specimen types for flow cytometric analysis. Blood Collection TransFix®/EDTA Vacuum Blood Collection Tubes (TVT) 3 and 9 mL direct draw collection tubes prefilled with sufficient TransFix® and K3EDTA for the stabilisation and anticoagulation of blood at the point of collection and for up to 14 days. Cerebrospinal Fluid TransFix® CSF Sample Storage Tubes Sample storage tubes optimised to stabilise CSF for up to 3 days. Two formats available, small (for 0.25 – 1 mL samples) and large (for 1 - 4 mL samples). Circulating Tumour Cells Circulating Tumour Cell TransFix®/ EDTA Vacuum Blood Collection Tubes Blood collection tubes prefilled with sufficient TransFix® for the collection and stabilisation of circulating tumour cells in a final draw volume of 9 mL. Sample Storage TransFix® Sample Storage Tubes Sample storage tubes for stabilising 1 mL of sample. These tubes do not contain an anticoagulant, allowing the stabilisation of blood collected with an anticoagulant other than EDTA. Why Stabilise Samples? REGULATORY STATUS TransFix®, TVTs and CSF products are registered IVD devices in the UK, EU and many other territories around the world. Once cells are taken from the body, they undergo apoptosis and enzymatic degradation which diminishes cell numbers and distorts the true immunophenotype of the specimen. Over time, cell sub-populations in aged samples become indistinguishable, rendering the sample unsuitable for flow cytometric analysis. Stabilising your samples with TransFix® allows you to maintain the immunophenotype of the cells for longer. ORDER NOW! Visit: www.caltag.co.uk/distributors to find your local dis

• Achieve greater efficiency in testing by batching samples. • Prevent the need for repeat phlebotomy or lumbar puncture due to degraded samples. • Perform additional tests on the same sample after the initial analysis, without patient recall. • Maintain sample integrity during transportation between clinical sites. • Improve pre-analysis variation by preserving all samples at the same time point. • Simply collect sample in the tube, or add TransFix to your sample and mix by inversion. • Eliminate the need for weekend and evening work. • Mitigate the impact of unexpected machine breakdown or...
