Why is it important?
Protein aggregation in living systems often occurs at much lower concentrations, even in the nanomolar range, and involves nanoscale clusters that traditional experiments struggle to detect. This study addresses this challenge by using fluorescence correlation spectroscopy (FCS) to identify and analyze protein aggregates at these extremely low concentrations and sizes, bridging a crucial gap between in vitro studies and real cellular conditions.
Perspectives
This work underscores the power of cutting-edge biophysical tools like FCS to bridge gaps in understanding protein behavior. It’s exciting to see how the method's precision reveals the hidden details of protein clumping, opening up new paths for tackling complex diseases.
