Biochemistry at the Single Cell Level

Dataset #811: 090902-PBMC stim with IL6, IL10, LPS (Public Version)

Western blots are great. That is, unless you’re studying signal transduction in a mixed population of primary cells. The amount of material necessary for many biochemical techniques is usually not practical when working with patient samples or rare cell populations.

Flow cytometry to the rescue! Phospho-flow tracks biochemistry at the single cell level. Simultaneous assessment of cell surface markers and signaling events for individual cells enable biologists to profile disease samples or monitor the effects of drugs in clinical samples. More »

Take the U937 Challenge!

Dataset #61: Welcome to Cytobank – U937 dataset

So you want to do phospho-flow? Take the U937 challenge!

What is phospho-flow? It’s a specialized form of flow cytometry that enables biologists to probe signaling activity inside the cell. Flow cytometry has been widely used to analyze cell populations by probing the proteins that are outside on the cell surface. Phospho-flow cytometry includes a few extra steps – stimulation, fixation, and permeabilization – that enable researchers to also probe the transient phosphorylation state of intracellular signaling proteins.
