Thrilled to share "in situ APEX activation" (iAPEX), a proximity labeling technology for subcellular #proteomics applied to primary #cilia. iAPEX uses an enzymatic cascade, in which a D-amino acid oxidase locally produces H2O2 to activate ascorbate peroxidase.

What looks like art is actually biology — a rat liver cell seen under the microscope.
Those glowing strands are actin and microtubules, the scaffolding that lets the liver filter blood, detoxify chemicals, and even regrow itself.
