Applications 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, theCountstarsystem can be used for every step of the cell manufacturing process.

T/NK cell mediated cytotoxicity

By labeling the target tumor cells with CFSE ortransfectwith GFP. Hoechst 33342 is used for stain all cells (both T cells and tumor cells), alternatively, target tumor cells can be stained with CFSE, PI is used forstainthe dead cells (both T cells and tumor cells). This staining strategy allows for the discriminate of different cells.

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® Rigel S5 offers a visualized image-based solution and analyzes all of these steps with pre-loaded protocols in depth.

Cell Cycle

CountstarRigel S5 enables users to get the result of a cell cycle quickly and accurately.CounstarRigel S5 can analyzeproportionof cell indifferentphase of the cell cycle.

Surface Maker Analysis

A lymphocyte subsets analysis is a typical experiment performed incell relatedresearch fields and various diseases diagnosis. Countstar® Rigel S5 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.TheCountstar® Rigel S5 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 cytometry requires a high-qualified and experienced operator. WhileCountstarRigel S5 enables users to get the result of a transfection efficiency assay quickly and accurately.

Applications 1. Trypan blue cell counting and viability

Countstar is applicable to cells with diameter between 5-180um, like mammalian cell, insect cell, and some planktons.

2. Aggregated Cell Analysis

Some primary cells or subculture cells are prone to aggregate when poor culture state or excessive digestion, thus causing great difficulty in the counting of cells. With the Aggregation Calibration Function, Countstar® can realize a stimulation calculation of aggregations to ensure accurate cell counting and obtain the aggregation rate and the aggregation histogram, thus providing basis for experimenters to judge the state of cells.

Countstar can count the aggregated cells one by one.

3. Cell Size Analysis

The change of cell size is a key feature and is commonly measured in cell research. Normally it will be measured in these experiments: cell transfection, drug test and cell activation assays.

4. Overlay Analysis of the Cell Growth Curve

In cell culture, the study of pharmacology and toxicology often requires the overlay analysis of multiple growth curves in order to find the optimal culture conditions or the best dosage. Countstar® can directly call up multiple growth curves for comparative analysis.
