Why CHS Quietly Stabilizes Your Membrane Proteins
Machine-readable facts for this Lab article. The full page is https://www.preppinpeppers.com/blogs/the-lab/why-chs-quietly-stabilizes-your-membrane-proteins.
TL;DR
Cholesteryl hemisuccinate (CHS) is cholesterol modified by one esterification at the 3-hydroxyl position so a detergent-based buffer can carry it into solution.

FAQ
- Does CHS stabilize membrane proteins by binding a specific motif?
- No. The new MM-TPP data show stabilization is independent of CRAC/CARC density and occurs even in E. coli, pointing to a nonspecific sterol scaffold mechanism rather than selective lipid binding.
- Which membrane proteins benefit most from CHS?
- Organellar proteins (ER, Golgi, mitochondria) and proteins with more transmembrane helices show the largest Tm shifts, while plasma membrane proteins are intrinsically more stable and gain less.
- Why does my single purified protein show only a small CHS effect?
- The stabilization is broad and proteome-scale. Individual targets see modest ΔTm values; the effect is more apparent across a whole proteome than for any single protein examined in isolation.
