Count Star
Product feature

The BioApps of the Countstar Rigel S3 System simplify routine cell lab tasks while providing high quality scientific data.
Countstar S3 comes with three BioApps to simplify and automate the routine cell count, viability and cytotoxicity tasks.

AO/PI Viability ProtocolAO/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 AntibodyAffinity of Antibody: This assay run as Green color assays in FITC binding antibody to determine the affinity of the biosimilar drug.
Surface Marker AssaySurface Marker Assay: Quantify specific cell populations based on surface marker expression (CD45+ CD4+, CD8 + MSC, CD56+ NK cells, etc.)
Cell CycleCell 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 ApoptosisCell Apoptosis: Cell Apoptosis assay is a type used for determining the apoptosis percentage of cells by Annexin V-FITC/7-ADD staining method. 
GFP transfectionGFP 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 KillingCelling Killing: Run three fluorescence color assays in disposable consumable to determine the CAR T/NK-Mediated Cytotoxicity using Tracer and Viability Dyes 
Trypan blue ProtocolsTrypan blue Protocols: Obtain cell count, viability and concentration estimations based on trypan blue staining using a disposable consumable.

Three step process

The Countstar S3 System is designed to take you from sample to result in one go, simplifying your work and allowing for increased productivity and efficiency.
