Liquid Tumors

Liquid Tumors or non-adherent cells
Request Information

Liquid tumors such as leukemia, lymphoma, and myeloma are composed of non-adherent cancer cells. These free-floating liquid tumor cells represent an important target in immuno-oncology but assaying suspension cell cultures can be challenging as cells can be easily washed away or disturbed, hindering further measurements. To create more effective strategies for the treatment of blood cancers, accurate assessments of in vitro target-cell killing are critical.

Many hematological cancer cell lines can be analyzed using the Maestro platform. Using an antibody-tethering technique to immobilize the target cells you can monitor cell growth in real time.

Liquid tumor cell lines can be assayed in real time. (Left) Daudi cells on a CytoView-Z 96 plate as imaged by the Omni. (Middle) Proliferation of antibody-tethered vs non-tethered Daudi cells as measured by the Maestro Z shows the increase in signal achieved with antibody-tethering. (Right) The tethering technique is broadly applicable as demonstrated in liquid tumor cell lines Daudi, K562, and Raji across a range of cell densities.
