When E2Fs are bound to Rb, not only are they transcriptionally inactive, but they also function to repress transcription by recruiting chromatin-modifying enzymes that promote deacetylation and methylation of specific histone lysines.

Techniques for Measuring Stability

Absorbance (e.g. Trp, Tyr) 

Fluorescence (Trp)-difference in emission max & intensity.

CD (far or near UV) - (2o or 3o) 

NMR 

DSC (calorimetry) 

Urea gradient gels - difference in the migrating rates between F and U.

Catalytic activity 

Chromophoric or fluorophoric probes/FRET

The Cp heat capacity of a defined system is the amount of heat (usually expressed in calories, kilocalories, or joules) needed to raise the system's temperature by one degree (usually expressed in Celsius or Kelvin).
