Countstar® Rigel S3

Up to 4 fluorescent channel and one bright field analysis at the same time

13 different fluorescent analysis combinations

User Friendly Cell Analysis Protocols

Trypan blue Protocols: Obtain cell count, viability and concentration estimations based on trypan blue staining using a disposable consumable.
AO/PI Viability Protocol: Run two fluorescence color assays in disposable consumable to determine the percentages of live, dead cells and concentration in the presents of debris and unwanted nonnucleated cell types including red blood cells.
Affinity of Antibody: This assay run as Green color assays in FITC binding antibody to determine the affinity of the biosimilar drug.
Surface Marker Assay: Quantify specific cell populations based on surface marker expression (CD45+ CD4+, CD8 + MSC, CD56+ NK cells, etc.)
Cell Cycle: Propidium iodide (PI) is a nuclear staining dye that is frequently applied in measuring cell cycle. The protocol determining cellular DNA content in cell cycle analysis
Cell Apoptosis: Cell Apoptosis assay is a type used for determining the apoptosis percentage of cells by Annexin V-FITC/7-ADD staining method.
GFP transfection: The green fluorescent protein (GFP) exhibits bright green fluorescence when exposed to light in the blue to ultraviolet range. This protocol can analyze counting and percentage of GFP.
Celling Killing: Run three fluorescence color assays in disposable consumable to determine the CAR T/NK-Mediated Cytotoxicity using Tracer and Viability Dyes

GMP and 21 CFR part 11 ready

Make a detailed record of any changes, edits, deletions, adjustments, etc. Electronic records cannot be deleted, including administrators. Electronic records include date, time, user name, machine serial number, and user's actions

FCS Express Software

The optional De NovoTM FCS Express software makes graphs touchable and customizable fluorescence channel boost your experiment reach. Countstar FL together with FCS Express is able to analyze for the cell apoptosis, cell cycle, transfection, affinity of antibody, CD marker and etc.

Dual-Fluorescence Viability:
Acridine orange (AO) and Propidium iodide (PI) are nuclear nucleic acid binding dyes. The analysis excludes cell fragments, debris and artifacts particles as well as undersized events such as platelets, giving a highly accurate result. In conclusion, the Countstar system can be used for every step of the cell manufacturing process.

Cell Apoptosis
The different phases of apoptosis are segmented into an early, middle and late stage. Specified indicators can document the single stages of apoptosis. The Countstar® FL offers a visualized image-based solution and analyzes all of these steps with pre-loaded protocols in depth.


Cell Cycle
Countstar Rigel S6 enables users to get the result of a cell cycle quickly and accurately. Counstar Rigel S6 can analyze proportion of cell in different phase of the cell cycle.

Surface Maker Analysis
A lymphocyte subsets analysis is a typical experiment performed in cell related research fields and various diseases diagnosis. Countstar® Rigel S6 offers a faster and easier way to make immune cell typing more efficient.  With visible cell images and powerful data analysis

Affinity of antibody
Detect affinity of antibody in cell level is an important indicator of monoclonal antibody detection using immunofluorescence method.The Countstar® Rigel S6 offers a rapid, direct and reliable evaluating method for the affinity of antibody detection in antibody drug screening


GFP Transfection Efficiency
In cell and molecular biology, the GFP gene is frequently used as a reporter of expression. Currently, scientists are commonly using the fluorescent microscopes or flow cytometers to analyze the transfection efficiency of mammalian cells. But Flow cytometer requires a high-qualified and experienced operator. While Countstar Rigel S6 enables users to get the result of a transfection efficiency assay quickly and accurately.
