The Loading Dye * Loading dye is a colored buffer mixed with the DNA prior to loading onto the gel. The loading dye contains a relatively high concentration of either glycerol or sucrose. This makes the solution more dense than the surrounding running buffer so that when a sample is pipetted over top of a well it sinks down into the well.
It can be seen that addition to a cationic dye-dyeable polyester resin of the melt viscosity depressants to be used in the present invention has no adverse influence on dyeability or fastness to sublimation of the polyester resin during storage.atents. A cationic dye-dyeable polyester resin composition comprising a cationic dye-dyeable polyester resin and a melt viscosity depressant. Addition of the melt viscosity depressant to the cationic dye-dyeable polyester resin reduces the melt viscosity of the resin without decreasing the intrinsic viscosity...
