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

Due to C-terminal prenylation of lamin B, 

lamin B dimers remain associated with the nuclear

#Unit 2. Cellular Organization

During telophase, de-phosphorylation by specific phosphatases promotes lamin reassembly, which is critical to re-formation of a nuclear envelope around the daughter chromosomes.
