This talk was given by Faris Naji CEO of Tercen to Cyto Virtual 2020 seminar on August 4th.

He outlines the state of data analysis for Flow Cytometry and how Tercen can provide innovative ways to apply the latest statistical techniques.

Flow Cytometry: The Move To High Dimensional

Flow cytometry is a widely applied approach to exploratory immune profiling and biomarker discovery in healthy or pathological conditions.

Flow cytometry uses antibodies tagged with fluorochromes or fluorescent dyes for which novel methods allow up to 50 detection parameters.

More recently, an innovative technology using stable metal isotopes instead of fluorochromes has emerged. Mass and spectral cytometry has enabled high dimensional analysis and resulted in new research opportunities and challenges.

Scientists can no longer manage with the classical bi-axial gating strategy and they need new algorithms, statistical knowledge, terminology, and tools to develop standard analysis approaches.

Tercen: the New High Dimensional Flow Cytometry Analysis Tool

Tercen tutorial material demonstrates how to use workflows, dimension reduction (e.g. PCA, tSNE, UMAP), clustering (e.g. FlowSOM), and marker metrics (e.g. MEM scores).

In addition, Tercen gives users the opportunity to integrate different types of data to high dimensional flow cytometry and boost biomarker discovery.
