Development of a sensitive peptide-based immunoassay: application to detection of the Jun and Fos oncoproteins.

abstract：:The organization principles underlying non-membrane-bound organelles have started to unravel in the past 10 years. A new biophysical model known as biomolecular condensates has been proposed to explain many aspects of membraneless organelle assembly and regulation. Neurons are extremely complex, and each neuron can co...
