Why Cellometer K2?

  1. Primary Cell Analysis
  2. Live/Dead Nucleated Cell Counts
  3. Cell Based Assays: Cell Cycle, Apoptosis, GFP

The Cellometer K2 utilizes bright field imaging and dual-fluorescence imaging to quickly and accurately identify and count individual cells. Cell count, concentration, diameter, and % viability are automatically calculated and reported.

The Cellometer K2 is specifically optimized for analysis of primary cells from peripheral blood, cord blood, bone marrow, and other complex samples for use in a wide range of research areas, including:

  • Nucleated Cells for Transplantation
  • PBMCs for Immunology
  • Splenocytes for Vaccine Development
  • Stem Cells for Cellular Therapy
  • Tumor Cell Suspensions for Oncology

Dual-color fluorescence allows for staining of live and dead nucleated cells, generating accurate viability results even in the presence of debris, platelets, and red blood cells. Accurate analysis of both ‘messy’ and ‘clean’ samples enables the K2 to evaluate samples at a variety of points throughout sample processing – from initial collection to separation, to cryopreservation.

The dual-fluorescence AO/PI method utilizes nuclear staining dyes that bind to nucleic acids in the cell nucleus. Because most mature mammalian red blood cells do not contain nuclei, only live and dead mononuclear cells produce a fluorescent signal. There is no need to lyse red blood cells, saving time and eliminating an extra sample preparation step. Red blood cells, platelets, and debris are not counted in the fluorescent channels.

These images (right) demonstrate the advantage of fluorescent counting for primary cells. The bright field image shows the combination of nucleated cells, red blood cells, and platelets present in the sample. Only the live and dead nucleated cells are visualized and counted in the green and red fluorescent channels.
