Täby, Sweden: – Scandinavia’s leading supplier of validated biotechnology products, Nordic BioSite, has highlighted the importance of its new TransFix® cellular antigen stabilisation reagent and how it can be used to stabilize lymph node biopsies or fine needle aspirate specimens for flow cytometry.

This is significant in allowing a wider window for the performance of lymph node flow cytometry, which is a key tool in immunology and oncology.

Key to lymph node biopsies

Lymph nodes, an important part of the immune system, are small, oval-shaped organs found close to the stomach, intestines, and lungs and commonly noted in the armpits, groin, and neck.

Lymph node biopsies such as fine needle aspirations or open biopsies are often performed to confirm suspected lymphomas (for example, Hodgkin’s lymphoma), or to determine if secondary tumors may have spread from other sites (for example in metastatic breast cancer). Cells from these biopsies can then be disaggregated and analyzed by flow cytometry.

Time critical

Previous research (Darzynkiewicz et al., 2011) has confirmed that time is critical for the enumeration of cells from lymph node biopsies and other solid tissue via flow cytometry, because cells and cellular antigens degrade quickly ex vivo.

“Therefore, immunophenotyping historically had to be performed as quickly as possible,” says Nordic BioSite.

“TransFix has been used to stabilize cellular antigens and increase cell yields within fine needle aspirations and other lymph nodes biopsies. This allows immunophenotyping by flow cytometry to be conducted at a time that is more convenient to the operator,” the company points out.

Preventing cellular degradation

TransFix® is a cellular antigen stabilisation solution developed by UK-based Cytomark, a division of Caltag Medsystems Ltd., which is dedicated to the development of cell stabilization reagents for use in flow cytometry.

It prevents cellular degradation in a variety of specimen types for flow cytometric analysis and can also be applied to stabilization of human or animal blood, cerebrospinal fluid, bone marrow or circulating tumor cells.

Independent research studies have successfully used TransFix® to stabilize cells from lymph node biopsies, including fine needle aspirations.

Nordic BioSite can supply TransFix in 1 and 20ml aliquot sizes and in pack sizes of 10 and 50 1ml tubes to give end-user more flexibility in application of TransFix to research samples.
