Critical micelle concentration (CMC) is defined as the concentration of detergents above which micelles are spontaneously formed. The CMC is important in biology because at concentrations above it the detergents form complexes with lipophilic proteins. Below this borderline, detergents merely partition into membranes without solubilising membrane proteins.
| Detergent | CMC (mM) | MW (-H2O) | Type |
|---|---|---|---|
| BRIJ 35 | 0.09 | ~1200 | non-ionic |
| NP-40 | 0.05-0.3 | 603 | non-ionic |
| Triton X-100 | xxx | yyy | non-ionic |
| Tween 20 | 0.059 | - | non-ionic |
| SDS | 7-10 | 288.5 | ionic |
| CHAPS | 6-10 | 614.9 | zwitterionic |
