CRG/UPF Flow Cytometry Unit

The CRG/UPF FACS Unit hosts six analysers and two sorters. The sorters are operated by the facility personnel as well as by some advanced users. The analysers are operated by the users themselves after they have been trained. The facility personnel help with experimental design and data analysis, as well as supervising and monitoring the experiments when necessary.

High quality control standards, as well as standard QC procedures suggested by the manufacturer, are applied to the instrumentation to avoid unwanted technical errors and achieve maximum instrument performance.

User feedback through an annual satisfaction survey and an advisory committee Ad Hoc discussion is widely appreciated for quality control of the services provided.
