High-throughput live-cell analysis system

A far-red viability dye staining nuclei in dead / apoptotic cells.

Ready-to-use, dropper bottle far-red viability probe

Apoptosis is a normal physiologic process which occurs during embryonic development as well as in maintenence of tissue homeostasis. The apoptotic program is characterized by certain morphologic features, including loss of plasma membrane asymmetry and attachment, condensation of the cytoplasm and nucleus, and internucleosomal cleavage of DNA. Loss of plasma membrane is one of the earliest features. In apoptotic cells, the mem…

The LUNA-STEM™ takes adipose-derived stem cell and SVF samples to count live nucleated cells, dead nucleated cells, and non-nucleated cells with precision and consistency for downstream procedures.

Yeast strains used in food and drink production can be notoriously clumpy.  The LUNA-II YF™ has an autofocusing cell counting and declustering algorithm that counts individual yeast cells in just 15 seconds.

The ApoTox-Glo™ Triplex Assay combines three assay chemistries to easily assess viability, cytotoxicity and apoptosis events in the same cell-based assay well. First, viability and cytotoxicity are determined by measuring two differential protease biomarkers simultaneously with the addition of a single nonlytic reagent containing two peptide substrates. The live-cell protease activity is restricted to intact viable cells and i…

The Griess Reagent System measures nitrite (NO2–), which is one of two primary stable and nonvolatile breakdown products of nitric oxide (NO). Nitric oxide is an important physiological messenger and effector molecule in many biological systems, including immunological, neuronal and cardiovascular tissues. This assay relies on a diazotization reaction that was originally described by Griess in 1879. Through the years, many mod…

The CellTiter-Glo® Luminescent Cell Viability Assay(a,b) is a homogeneous method of determining the number of viable cells in culture based on quantitation of the ATP present, an indicator of metabolically active cells. The CellTiter-Glo® Assay is designed for use with multiwell formats, making it ideal for automated high-throughput screening (HTS), cell proliferation and cytotoxicity assays. The homogeneous assay procedure in…
