A mobility shift assay is electrophoretic separation of a proteinâDNA or proteinâRNA mixture on a polyacrylamide or agarose gel for a short period (about 1.5-2 hr for a 15- to 20-cm gel).
A series of structurally related molecules in a substitution series can also show a hypsochromic shift. Hypsochromic shift is a phenomenon seen in molecular spectra, not atomic spectra-it is thus more common to speak of the movement of the peaks in the spectrum rather than lines.ecause the blue color in the visible spectrum has a shorter wavelength than most other colors, this effect is also commonly called a blue shift. This can occur because of a change in environmental conditions: for example, a change in solvent polarity will result in solvatochromism.
