Primary Function: The BD FACSVerse Flow Cytometer is a versatile flow cytometry system engineered for acquiring and analyzing particles or cells in a liquid suspension, primarily for identifying and characterizing different cell populations. It is designed to offer remarkable performance, flexibility, and ease of operation for research applications.

Operational Principle: Antibodies specific to cell proteins are labeled with a fluorescent dye and incubated with the cell suspension. The suspension flows through the cytometer and is interrogated by lasers which excite the fluorescent antibodies. The emitted fluorescence and scattered light are captured, and the resulting data is analyzed by the BD FACSuite software to reveal detailed information about the cells, including their phenotype, size, granularity, and protein expression.

Key Features & Innovations: The BD FACSVerse system incorporates built-in intelligence to reduce errors, increase efficiency, automate processes, and minimize user interaction. Its compact optical system utilizes free-space lasers to concentrate intensity at the flow cell, minimizing light loss and maximizing resolution for multicolor applications. The vacuum-driven fluidics system, combined with a unique Sample Injection Tube (SIT) and a stainless steel flow cell, enhances reliability, signal resolution, and reduces issues like bubbles and thermal expansion.

Workflow & Software: The system is controlled by BD FACSuite software, which streamlines processes from setup through data acquisition, analysis, and shutdown. It guides users through configuration management, performance qualification, fluorescence characterization, and spillover correction. The software supports pre-defined research assays and allows users to create and share customized experiments, ensuring reproducible data across different systems and laboratories.
