Features of the Spectrum Image Cytometry System

The Spectrum Image Cytometer — a customizable cell counting and cytometry instrument — offers flow-like data with predesigned templates. Users can rapidly plot cell population data as a histogram, contour plot, scatter plot, or dot plot using FCS express.

The user-changeable filter sets allow users to adapt the instrument for particular reagents or assays of interest.

All-in-One System

The Spectrum Image Cytometer helps perform cell-based assays, primary cell viability, and basic cell counting.

Dual-Fluorescence for Accurate Primary Cell Viability

There is no interference from red blood cells. Users can analyze, cord blood, peripheral blood, and bone marrow without lysing.

Unique Algorithms for Advanced Cell Analysis

Viability and concentration of adipocytes, hepatocytes, and other advanced cell types can be easily determined.

Fast Results

Cell counts, images, viability calculations, and size measurements can be obtained in less than 30 seconds for each sample.

Simple Cell-Based Assays

  • Small 20 µL sample size
  • Pre-defined instrument settings
  • Pre-qualified reagents
  • Easy image-based analysis
  • Precise and reliable results
  • Assay-specific data templates

Advantages of Image Cytometry

Cell Images can be Viewed

  • Users can ensure that only the target cells are counted
  • Cell morphology can be visually checked
  • Images meant for publication can be exported
  • Cell images can be archived and re-analyzed

Proprietary Pattern-Recognition Software

Non-Fluidic Platform

  • Does not require maintenance
  • Disposable counting chambers avoid the need for washing
  • Sturdy optics modules and LED light sources
  • Can be used with delicate cells

IQ/OQ Validation and GMP/GLP Accessories

  • Operational qualification reagents or protocol
  • Installation qualification reagents or protocol
  • GMP/GLP software module
  • On-site OQ or IQ performance

Proven Results

  • Cell samples with different viability (0%–100%) can be precisely quantified
  • Cell viability can be rapidly determined for primary samples or cell lines using AO/PI
  • Up to 2 × 107 cells/mL can be imaged and counted
  • Acridine orange (AO)-stained cells (shown above) can be automatically identified
  • Versatile platform — can be used for complex cell-based assays and routine cell counting
  • Image acquisition and analysis: It takes 30 seconds per sample for a three-channel assay
