Especially useful with precious or difficult samples, magnetic levitation allows users to separate live from dead cells in a fast, simple, and gentle process.
For detection and screening of circulating tumor cells (CTCs), the Levitas system solves key technical challenges.
Accurate separation and identification of key cell types, such as activated leukocytes and transfected cells
Real-time drug response offers a fast, accurate, and simple approach to antibiotic resistance testing.
Effective, fast, and simple separation of differentiated cells from stem cells or iPSCs.
The platform is simple, allowing users to begin with unprocessed whole blood samples or any sample with cells in suspension. In a matter of minutes, the instrument and its software automatically perform levitation; label-free separation; quantification of results based on high-resolution imaging; and analysis by cell number, morphology, and levitation profile. Internally, the system relies on a cell densitometry platform consisting of two magnets mounted on either side of a millimeter-wide capillary channel with mirrors on either side to measure levitation height with a microscope. Both brightfield and fluorescence images are collected.
The process has been tested for a number of cell types and states which include:
