Add New Depth to Rare Cell Studies with the Efficiency, Ease, and Versatility of Celselect Slides™

The complexity of life is rooted in cells. From cell structure, to genetic variability, gene expression, and the formation of complex tissues and organs, all of biology is dependent upon this basic unit. The selection, capture, and study of cells, particularly rare cells, treated cells, or cells within a mixed cell population, is essential for providing insight into diverse areas such as the mechanisms of cancer and metastasis, disease, symbiosis, and biological diversity.

The Genesis Cell Isolation System with Celselect slides technology achieves fast, efficient selection and capture of viable individual cells 8-30 µm in size from liquid biopsy, cell culture, and other liquid sample types using gentle microfluidics and size-based, cell selection.

How Could Your Cell Research Benefit with Celselect Slides Technology?

Examine how the Genesis System with Celselect Slides™ can be used for efficient capture, recovery, and analysis of circulating tumor cells (CTCs) from liquid biopsy samples. Imagine what you can do with Celselect technology with your cells!

Meet our 2023 Celselect Grant Recipients

In 2023 we created the Celselect Research Grant Program to support excellence in single- and rare cell research. After a rigorous selection process, we’re pleased to announce those scientists who were selected to receive a 2023 Celselect Research Grant. Exciting research begins for these 10 single-cell researchers who will use the Genesis Cell Isolation System and Celselect Slides™ to study topics from CTCs and cancer metastasis, to exercise-induced conditioning of PBMCs to promote vascular benefits. We'll be highlighting the work of all of this year's Grant recipients in the coming weeks, but you can learn more about their research right now here.
