Validated antibodies for rare cell and circulating tumour cell enumeration 

Antibodies

Bio-Rad Laboratories has launched validated antibodies for rare cell and circulating tumour cell (CTC) enumeration for use with Bio-Rad’s Celselect Slides Enumeration Stain Kits. 

The antibodies are specific to CTC surface markers to enable the sensitive and specific identification of target cell populations, enhancing the study of tumour heterogeneity and disease progression at various stages. 

The enumeration of captured CTCs provides valuable insights into the surface markers that indicate cancer type and progression and is critical to understanding the mechanisms of cancer metastasis. For successful enumeration, the antibody reagents require careful selection to ensure not only sensitivity and specificity to the target cell surface marker, but also compatibility with the staining method. Bio-Rad’s new range of validated primary and secondary antibodies enables accurate immunostaining of captured CTCs, supporting cancer researchers working in this field. 

“CTC analysis is a promising tool for the study of tumour heterogeneity and disease progression, offering real-time data and unique insights into cancer metastasis,” said Stephen Kulisch, Vice President of Marketing for Bio-Rad’s Digital Biology Group. “The introduction of validated antibodies for target cell identification reflects Bio-Rad’s growing single-cell oncology product portfolio.”
