8+ What's a Turnkey Solution? [Quick Guide]

A ready-to-use, complete product or service that is immediately ready for operation by the purchaser. It represents a fully configured system or solution that addresses a specific need without requiring any further assembly, integration, or configuration by the end-user. For example, a company might purchase a fully equipped and operational manufacturing facility, ready to begin production from day one; this exemplifies such an offering.

The value of such an offering lies in its ability to save time, resources, and expertise for the buyer. It eliminates the complexities and risks associated with designing, building, and integrating separate components. Historically, such approaches became popular as businesses sought to rapidly deploy new capabilities and focus on core competencies rather than on the technical details of implementation. This approach accelerates project timelines and reduces the potential for errors and delays.

6+ PBS Solution in Flow Cytometry: What Is It?

A phosphate-buffered saline solution serves as a fundamental component in flow cytometry. This isotonic solution, typically composed of sodium chloride, sodium phosphate, and, in some formulations, potassium chloride and potassium phosphate, maintains a stable pH and osmolarity, mimicking physiological conditions. Its primary role is to suspend cells or other biological samples during the analysis process, ensuring that cells remain viable and retain their native properties. For instance, cells stained with fluorescent antibodies are often washed and resuspended within this solution prior to their introduction into the flow cytometer.

The significance of this buffered solution stems from its ability to minimize cell damage and aggregation, both of which can negatively impact the accuracy and reliability of flow cytometry data. By providing a stable and compatible environment, it prevents osmotic shock and preserves cellular integrity. Its use dates back to the early development of flow cytometry and has become a standardized practice, contributing substantially to the reproducibility and robustness of experimental results. Its well-defined composition and buffering capacity make it an invaluable reagent in cell-based assays.
