•DRAQ5™: A validated far-red fluorescent DNA dye for live or fixed cell analysis. It is spectrally compatible with most visible fluorophores, including GFP/FITC and R-PE, and enables nuclear counterstaining without UV excitation. Suitable for fluorescence microscopy, high-content screening, and flow cytometry, it allows direct DNA content analysis in blood or bone marrow without red blood cell lysis or fixation/permeabilization.

•DRAQ7™: A far-red fluorescent DNA dye that selectively stains nuclei in dead or permeabilized cells. It is widely used in imaging, flow cytometry, and screening applications, with strong compatibility across standard instrument platforms and protocols.

•DROP & GO™: A ready-to-use formulation of DRAQ7™, designed for convenient application. This far-red/near-infrared DNA dye selectively stains nuclei of dead or permeabilized cells and is suitable for long-term assays.

•HypoxiTRAK™: A near-infrared fluorescent probe that enables detection of hypoxia at the single-cell level. It is non-toxic to normoxic cells and provides a functional readout of hypoxic conditions. Compatible with flow cytometry and fluorescence imaging, and spectrally aligned with common fluorophores such as FITC and R-PE.

•DRAQ9™: A far-red fluorescent dye designed to label membrane structures within the cytoplasm. It is water-soluble and membrane-permeable, making it suitable for live cell staining, long-term tracking, and multiplexing with other fluorescent probes.

•DRAQfx™ FIX & GO: A ready-to-use formulation of DRAQfx™, a far-red/near-infrared DNA dye optimized for efficient nuclear staining of fixed cells.

•APOPTRAK™: A chemical derivative of DRAQ5™, functioning as a cell probe that can penetrate both intact and compromised cells, enabling assessment of cell membrane integrity at the single-cell level.

•CYTRAK Orange™: An orange fluorescent dye related to DRAQ5™, capable of staining both nuclei and cytoplasm. It is water-soluble and membrane-permeable, and can be used alongside common fluorophores, particularly GFP fusion proteins, FITC-labeled antibodies, and far-red dyes.

•CyGEL™: A thermoreversible gel compatible with live cells and biological samples. It enables immobilization of non-adherent cells and beads upon heating and allows recovery upon cooling. Uniquely, CyGEL™ is liquid at low temperatures and forms a gel at higher temperatures, supporting flexible experimental handling.
