Even after enrichment steps—such as Ficoll, lysis, or microfluidics—significant numbers of red blood cells (RBCs) often remain, which can prohibit effective downstream analysis of circulating tumor cells (CTCs).
CTCs enable a powerful new opportunity for liquid biopsies to diagnose, phenotype, and manage cancer noninvasively. The extreme rarity of these cells make it challenging for CTC isolation with millions of neighboring leukocytes and billions of red blood cells.
When peripheral blood is harvested and cleaned up with a combination of density gradient and microfluidics, the sample may still contain over 90% RBCs. This is a problem.
In fact, in our conversations with researchers, we have heard firsthand how red blood cells get in the way:
With the Akadeum Human RBC Depletion Microbubbles, rare target populations are enriched in 10 minutes, allowing for higher efficiency of downstream single-cell analytics. Akadeum’s microbubbles provide a fast, easy, and gentle way to remove RBCs that persist after initial processing of blood or tissue.
Perform a quick clean up in 10 minutes before identifying, isolating, and analyzing CTCs. Save 30 minutes or more per prep.
Complete the whole process within a single tube. All you need is our microbubble reagent and gravity. No magnet is required: Save the $500–1000 you would spend on buying a magnet.
Up to 99% removal of RBCs from samples in less than 10 minutes start-to-finish without losing precious CTCs—keep the CTCs, lose the RBCs.
