The BD FACSLyric has been designed to achieve a high level of standardization. During assay development, the instrument and assay settings can be precisely defined and maintained. These settings can be easily transferred to another cytometer, thereby substantially reducing instrument to instrument variation. The BD FACSLyric system maximizes repeatability and accuracy of results especially for multi-site studies and simplifies assay transfers. Assay portability, pre-defined assays for clinical and IVD applications and software equipped with 21 CFR part 11 option, facilitate the compliance with regulatory requirements.
