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.

Upon secretion, Wnt proteins associate with glypicans (heparan sulfate proteoglycan) in the ECM, which restricts diffusion and leads to a greater accumulation of Wnt closer to the source of production.

In the case of a DNA helicase that functions on the lagging-strand template of the replication fork, the polarity is 5’->3’ to allow the DNA helicase to proceed toward the duplex region of the replication fork The PhiX system, named originally for phage X174, requires an initiation complex consisting of additional components, called the primosome. This system is used when damage causes the replication fork to collapse and it must be restarted.

CONSTITUTIVE PHOTOMORPHOGENESIS1 (COP1), another negative regulator of photomorphogenesis, is a component of the E3 ubiquitin ligase complex that targets photomorphogenesis-promoting proteins for degradation such as phyA, phyB.
